Hey, I just wanted to thank you. In 2018, your review of Marin Four Corners helped me buy that bike and quit smoking for good. I went from 25 ciggies a day to zero and remain smoke free. Now I am getting a custom bike built for endurance rides. Thank you once again. may your channel grow by the thousands. :)
Wow this is amazing! I am so happy for you here and this made me smile so much. I hope the Four Corners treated you well. What have you got planned for the new bike? Well done on the lifestyle change, very impressive 👏💪
@@mammothjourneys I absolutely loved the bike. It is now without its shortcomings, of course, and maybe if i were to buy now I would choose Nicasio. But hell, that bike and thousands of miles covered on it have made me so much more tough. If i can can climb on that bike, every other bike will feel easy. The new bike is a hark back to old school: rim brakes, bar end shifters, all steel build and relatively lightweight (under 10 kilos). The only thing slightly modern would be tyre clearance which is for upto 35mm tires. I have never had a proper road bike so I thought why not start with something basic. Please keep up the good work, and interestingly, I was bout to buy the same effin pump!! glad I didn't, I will go for a Topeak now. :)
@@amitkumar-wj8gn That is very true, any future bike climbs will feel easy! What rides have you got planned with the new bike? Yes I will continue releasing stuff and thank you for the kind words - glad you avoided this pump! I also went for a Topeak - keep it simple.
@@mammothjourneys mostly day long rides in the hills and maybe some randonneuring events. But i made sure there are no multiple mounts n all, wanted a clean-lookin bike. Can always add a frame bag and a handlebar bag if i feel like. Marin FC was a lot of things, but for covering miles in a day, not so much. Hence the decision to get a good ol road bike.
@@amitkumar-wj8gn Nice thinking and this sounds like a great adventure. Remind me again where you are riding? Send over a pic of the new bike to my instagram - interested to see what it looks like
So would you suggest that pump for Schrader valves exclusively? Despite the issue you mentioned, it works good? I'm interested to use it for 650b tires (47-584), Schrader valves, 70 PSI max pressure (I only inflate them up 60 PSI max).
I've used it on Schrader with no issues at all. It being a screw fit means it's secure. So if it's in your price point then go for it! For that PSI you'll probably be able to hit it with this pump. I hope that helps 👍
I've had this issue with mine in the past. I've learned to tighten the valve cores down well, and not overtighten the hose when attaching it to the valve. I still agree with you that you shouldn't have to do this. I've not had the same issue with their Micro Floor drive pump, even though it also screws onto the presta valve. I've wondered if maybe a bit of oil or a thin layer of petroleum jelly on the inside of the pump would help. I assume that the issue is that whatever rubber they are using to seal against the valve is grabbing the valve too tightly
Reassuring to know others have had the same issue. I did try not screwing the hose as much and this certainly helped. I always felt a level of anxiety when I was removing the hose, never fun. I've heard their drive pump is really good, perhaps I just need to try some other pieces of their kit.
Criticism is spot on. I’ve used this pump for years and have a valve core tightener in my Lezyne multi tool unit. The pump is the only one that fits presta short valve stems so I’ve learned to live with it.
As in on the inner tube valve? That hasn't been mentioned and is not a bad suggestion as it's small. Would you still be able to get the pressure you want?
i've tried the SPORT DRIVE HV (base model) but to get 4 bar it's so hard ! .. I don't really know if the other expensive pumps do a better job because are still 6.2bar max..
Afraid I can't help with that one. I never get ones that are too expensive. I concede it'll never get the same pressure as a track pump, although I'm sure there are ones that can.
I haven't tried this but someone else suggested this as well, which seems like it would work. But by the time I got told about this I'd already bought another pump. When you give it a go let me know how you get on.
I've had this same problem with Lezyne when unscrewing the hose, but it happened after not using the pump for a long time and an easy fix was using a bit of Lithium grease on the nosel and it hasn't failed since, "best" mini-pump ever ;)
@@rgpeters that's what you want. Good to hear mate, I'll check it out. Do you apply to grease at home and leave it as is, or take the grease on a ride with you?
Wish I had seen this video a couple of months ago, before buying this piece of 'expensive' junk. My solution is to always carry a presta to schreader adapter, and never mess with the presta core again. Cheers from Argentina!
Sorry to hear you have had the same experience to me here mate. There are a few other suggestions from users here who have found ways to use it which could help. Hopefully you can then get the most out of the expensive junk!
Same happened to me as well. I was just furies. Expensive "high quality" pump failed me in a critical moment. I ditched cheap 3 euro pump because of my vanity. Fortunately I had some zip ties along to attatch the pump hose to the spoke.
Oh no mate that sucks. Sorry to hear you had the same experience. I was so annoyed when it happened and thought how stupid it was. Have you decided on an alternative pump? Where do you do your riding?
No problem at all, glad it was helpful. A few of the comments on here as well show it's not unique to me this experience. Which pump did you end up going with instead?
Here's what I do. 1. Screw hose to valve. 2. Screw pump to hose. 3. Pump up tire. 4. Unscrew pump from hose 5. Unscrew hose from valve. I don't touch the magic button. I use dt swiss valves (dt swiss rims). Not sure if the valve type would make any difference. Gut tells me no. Oh, one thing I do is I practice taking tire off, removing tubeless valve from rim, inserting tube, reinstall tire and pump up. I do this in a nice, dry home setting. Usually sealant takes care of punctures but I have had the situation where I had a sliced tire. So I put a dollar bill into the tire and add the tube. Been lucky with valve cores. Haven't had one unscrew on me yet. But it could happen.
Lost count of how many times I've let my buddies use this exact pump when their crappy blackburns couldn't get the job done or when their CO2 chucks froze open and emptied without seating on the valve, but yeah sure buddy, this is the "worlds worst bike pump"
Good to hear you've had a good experience and you've got to help others out - not all heroes wear capes! Quite a few others having similar experience to me, but equal number have yours, if I made a product I'd want to get higher than a 50% success rate. Anyways, happy riding mate and glad it's all working for you 👍
Happened to me on Saturday on a cold rainy day, pulled the core right out. Also pump threw the o-ring off, so I couldn't even pump it back up! Luckily we have just finished our coffee shop stop and a kind gentleman driving by happened to see us struggling and had a floor pump! So now I'm ordering a new o-ring kit and some silicone grease to hopefully fix the pump. Would not have bought 2 of these pumps if I had known of this issue!
Oh no mate this is an absolute nightmare. Sorry to hear you are experiencing the same as few people on here. Some others users suggested some locktite which may work, perhaps something to try. Best of luck with the fix!
Hi Tekjim, you are the second person to recommend loctite, which would certainly work. Although this is an extra step you don't have to do with other pumps. If you were on a ride with mates or helping a stranger with a puncture, and needed to use your pump, you rely they have used loctite to have that assurance. I did try as well not to tighten too much onto the valve but found this made it less secure - but this did help things. Both are good suggestions but both are steps you don't need to do for other pumps. I presume you have a good experience with this pump which is ace to hear - appreciate the advice it's always helpful 😀
Explain to me how does removing a thorn causing a puncture is going to solve the problem without patching or replacing your inner tire by just pumping some more air in ? you won't get far like this or what am i missing :-) ?
@@Buzze1985 just tried to make the point of removing the thing that caused the puncture to the inner tube. Nothing on the tubeless front on this video. Hope that helps 👍
I have one of this pump, I don't like it either cause it's just too small and too slow. After I tried it once I switched to CO2. Just one thing, why do you use these detarchable valve core inner tube... You can use those non-removable valve inner tube that won't have this stupid problem..
Completely agree it would solve the problem. My tyres already had those types of tubes in, but since this pump when I replace them I choose the ones that can't be removed. CO2 is a great option, so much quicker.
Bought one last month while on vacation. Rubber hose part has has metal fitting which screws into the plastic threads on the pump body. Needless to say I didn't use the pump until we travelled on, only to discover the cheap plastic threads are stripped. Super expensive pump already, but now have to pay for shipping to send it back to where we bought it.
Oh no mate that is some rotten luck. Clearly someone not doing their QC checks! Hope you got your money back alright in the end. What did you go for in the end?
@@mammothjourneys Seems many products are "rotten luck" these days the way they build stuff now. I can name at least 6 overpriced items that were awful quality I purchased/replaced over the last year: that pump, eye glasses after one year the scratch proof coating began to separate from the lens, a short lived dishwasher, an outdoor light that leaks water into it, a very expensive mountain bike with 2 recalls and other horrid cheap parts on it, car tires that took no time to wear out, a rear view mirror for my car that falls off because the windshield replacers didn't use the correct mount. It's not just bad luck; it is modern day get rich quicker engineering scams. Have a good one!
Just had the exact same issue today on my ride. Pouring with rain when my puncture occurred. Left frustrated that i could for some unexplainable reason not get my new tyre pumped up fully as it would release the air. Tried the button and it was hopeless. So just got home and after a shower will order a different pump.
Oh Pala that sucks. I know your pain! What pump have you got in mind? The worst time to get a puncture is in the rain, and it's at that moment you want your kit to perform. Why would they design a pump which doesn't work?!
After the fail I had with this one I went for the Topeak Pocket Rocket mini pump. It seems reasonable so far but ironically since I bought it not had a puncture out on the road - can you believe it! Have you bought the Lezyne pump? If so a few people in the comments have suggested some options to make it work, have a read and I am sure it will help. If not, which pumps were on your shortlist?
@@mammothjourneys Thank you for the reply. I actually tried out Topeak's mountain morph pump at the shop today. I stopped forcing it once there is resistance in the cylinder. Do you force it further to put more air into the tires or is that a bad idea?
@@user-yu4kv4eb9h without a pressure gauge on the pump it's hard to know the true pressure in the tyres. With hand held pumps it's generally tough to over inflate. As they would be mostly used to get you home, simply squeeze the tyre by the side and compare with the other tyre. You don't want to overinflate as that runs the risk of bursting the inner tube. It would be helpful to have one pump at home with a pressure guage to reduce this risk. I'm not too bothered on my small hand held ones as I only use this in emergencies and I know I'll get tired or won't have the strength to over inflate when using it after repairing a puncture. What type of valve and tyre are you using on your bike?
@@user-yu4kv4eb9h I have actually bought this pump years ago. Incredibly practical to use it you have the space to carry it. The little foot stand is so helpful. Schrader generally have a lower pressure than presta, so just keep an eye on things when it becomes tough. Squeeze the tyre wall inwards and compare it to the other tyre. Once you get close to what the other one feels like stop. Hope that helps, happy riding!
You arent alone. I just had this happen in the mountains. Took over 45 min to fix and pumping up the tire 3 times in sub 40 F weather as it was getting dark. Nearly got stranded. Trying to figure out how to make this work. My bike shop mechanic said he has broken a valve a couple with regular hand pumps. So I'm not even sure if there is a good option other than CO2 at this point. Id like to get enough pressure to continue my ride as planned without a concern
Wowsers this is a miserable experience. Sorry to hear mate. When mine failed in the dark and raining all my toys were thrown out of the pram, I'm sure it was the same for you when it was that cold! Where was this? Did the bike shop recommend any suitable hand pump?
@@mammothjourneys Mountains in Southern California. And no unfortunately, the mechanic said he prefers the pumps with a hose attachment. Ones without you have to brace and can snap the valve. So both are flawed. Like someone suggested here Lezyne actually recommends a bit of Loctite on the valve. So I suppose I could add that to my spare tubes and make sure they are nice and tight. Other thought is maybe a small amount of grease to valve stem threads on spare tubes. I've also noticed comments saying 3 or 4 attempts to get it off. Maybe threading the hose off and on a few times may help. In either case I added a couple extra valves and a valve tool to my bag just in case.
@@starlitshadows interesting I've never had an issue with the normal hose attachment. All the suggestions on how to make it work I'm sure are effective, but an extra hassle you don't need with a normal attachment. Very jealous of south California, bet it's some epic riding there! What bike you got?
I totally agree with you that Lezyne, should have done a better job in testing their product. I also had a bad experience with the Lezyne Pocket HP when I had a flat tire towards the end of the ride and a fellow cyclist stopped to help me and you probably guessed he had that pocket pump and it happened as you’ve described in your video, twice .. I own several mini-size and a few floor pumps and I’m on the market for another one, something compact and reliable. That’s how I came across your video. I haven’t read all the comments, so I apologize if someone else has mentioned this or a similar solution. In, fact, I just tried this with a different pump just a few minutes ago, and it seems to work. I have a Schader to Presta valve adapter, which its weight is negligible, and I screw it on my Presta valve and pumped air into the tire effortlessly. So if people don’t mind carrying a small aluminum adapter, that may be the best course of action and you still keep your pump. In fact, you tighten up the inner core of the Presta valve once you are done and you can place the Schrader back on and live it there, so you won't forget it. Not an ideal situation, and does not excuse the manufacturer’s product flows, but you get to use your pump effectively since you have already made the investment. Just a thought..
Sucks to hear you had a bad experience with the pump. Twice is a bit brutal as well! No-one has recommended the adaptor yet which is a good option - how much did that thing cost? At least you don't have to shell out on a new pump which is good.
1) Tighten the valve core. This doesn't have to be super tight, but it should be snug. Even new tubes will likely need this done. You can use the tool on top of the chuck to do this, as your fingers likely do not have enough grip. To use the tool on the ABS-1 Pro, the plunger for the presta valve needs to be completely open, then the tool should be able to reach the flats on the valve core. 2) Do not over tighten the chuck on the tire valve. The chuck only needs the leading o-ring to touch where the valve core and valve stem meet. This will only be a few turns after the threads all engage. Threading the chuck on "until it stops" will possibly jam the valve core or plunger in the body of the chuck. 3) Use the ABS button on the chuck to bleed pressure. This removes the pressure from the hose, which will lower the friction on the valve core threads to make unthreading easier.
I hate this pump because I wasn't paying attention and accidentally bought the HP instead of the HV to pump up 29 x 2.6 tires. I've never used the button and haven't pulled out any cores, but I regularly add tire sealant and probably over tighten the cores, plus the sealant probably works like loctite. The pump gets very hot pumping up a big tire and the handle isn't very comfortable. I like the way the hose attaches to the tire because it provides different ergonomic options for pumping and it doesn't feel like I could accidentally break the valve stem. I just purchased the HV drive, hopefully I don't lose any valve cores, but I'm glad I know this issue exists and might add an extra core to my kit.
What might help is loctite which a few others have suggested in the comments, but not sure what effect adding sealant will have on that. Best of luck with it mate and hope this was helpful 👍
Because people with deep rims use valve extenders and because presto valve cores occasionally break off or suffer irreparable damage, while the rest of the tube remains perfectly intact (so it's thus convenient to just replace the valve core)
You had 5 similar pumps over 6 years? 🤔🤔 What were you doing where you had a turnover of almost 1 pump a year? I'd be questioning the quality. Happy riding mate 😁
Good to hear the other side of experiences here. A few have come up and said they've had no issues with it which is ace. Clearly me being a bit simple!
Just bought the Lezyne Micro Floor Drive HV for my fat bike. I hope it lives up to the positive reviews. It has a longer hose than yours but now I'm starting to worry.
From what others have said I don't think it will. Their floor/track pumps are all good. For what it's worth the craftsmanship of the product is good, so I am sure your pump will be ace. Let us know how you get on.
Yeah this seems the case from a few replies. I'm certainly not on my own with my experiences, but there are a few ways to make it work. Did you stick with it then and happy using it?
Never happened to me. I used to work in a bike shop where I had to pump thousands of bikes with Lezyne floor pump and NEVER remove the inner core of the valve, also my hand pump is Lezyne for more than 10 years. I had tens of flats and my pump was always helpful. I think this is just user error. Here we say "both hands are left".
Hi Nooski, Glad to hear you haven't had the same issues as I did, or some others who have left comments. Was the track pump you use a screw attachment or with the lever? My track pump is a lever and never had this problem. I presume your hand pump is the same model with the screw attachment. Do you get a better performance than a lever attachment type pump? I wonder if you did if it's worth the risk should the valve ever be screwed out? Although I can't deny it's user error! Love the saying as well.
@@mammothjourneys Hello, yes, older gold screw in type on floor pump. I have pocket drive hand pump with the same hose, it's just a bit shorter. It's important to release air from the hose bit you have mentioned this. Also from my tubular experience I have valve core tool in my wallet all the time but never really use it.
@@nooski_Watches-ik9nr It's so interesting how different the experiences people are having with this pump. Certain valves, and using a core tool to tighten them certainly helps, along with the air release from the hose. I did have occasions where it worked drama free, which perhaps made it more annoying and confusing when it didn't work! Glad to hear it worked though for you and the ride carried on!
That was a really interesting review. I didn't realise that was what that button was for. I'd heard of that sort of thing happening so I don't think you're alone. I guess I've been relatively lucky. Mine is old enough to predate the button and I'd never even realised they had a version that had the valve core tool either. The other night I actually managed to do that valve unscrewing trick by taking off a dust cap (no pump attached) and it made me realise I didn't have any useful tightening tools. I personally haven't had any issues with presta valves doing that with my lezyne, but I can't explain why. I don't think you're wrong with your general conclusions, although this is my favourite pump 😂. I suspect with modern materials if you buy a decent pump it ought to be good no matter what it's made of. And there are really good pumps with clamps instead of screw on if you get on better with them. I would definitely stick with a hose. That is definitely the one key feature I'd say everyone should be looking for in their pumps. No hose is my kryptonite when it comes to pumps.
Hi Colin, thanks for your insight here that's really helpful. Interesting you had this happen simply with your dust cap. I presume you're on the hunt now for a tightening tool to keep at home or put in your saddle bag??? I'm glad to hear though you are having a good time with the pump, I really wouldn't want anyone else to have the frustrtion I am having. I do believe this is massively 'user error'!
Thinking about the technique that I'm relatively unconsciously applying I think what I aim to do is ensure that the hose is perpendicular to the valve at the point it contacts the valve. I had lots of experience growing up using those old really long old fashioned type pumps that used to dominate cycling and learned that was ideal back then. Perhaps I had all my failures back then before I even saw a lezyne and so now largely I instinctively have a technique that minimises the chance of failures. Of course perhaps it's something else I'm doing even more unconsciously. I guess the failure modes are the interesting point. With the threaded sort you mostly have unthreading the core on a presta. I guess if you have more angular force on the hose then it might rub that core more and be more likely to undo it. If it's loose you may well catch it anyway. With the clamps the failure modes I've seen with presta are a) failing to get air in because the valve sticks (that seems to be resolvable by tweaking the valve before attaching, letting a little air out, ensuring it's not going to stick - this might happen with a threaded one too? Perhaps I'm mostly only using my threaded one from a flat tire so I notice it less with that? b) not having a secure enough connection to the valve so it blows off under pressure. c) possibly mangling the sticking out part of the valve if you're not careful - this one might be common to both types of attachment? I think bad experiences with clamps on small pumps without hoses may have made me more biased against the clamps. Threads I love the security that once attached it won't come off, and I've generally found it simple to attach and remove. I do use clamps with track stand pumps, and I have over the years learned how to deal with most of the failure modes. Honestly I don't think either way is perfect. I guess it depends on preference. The clamp probably has a less severe failure mode and is more intuitive, but I have had times where I've definitely been very frustrated with a clamped pump at times. I have found some of those tiny valve tools to carry around, but I'm wondering if I should get one of those hoses that came with your pump. My guess is that your problem isn't isolated because it seems that over the years Lezyne have been adding features that help to deal with it. First the button to release pressure, then the core tightening tool. The fact you can get spares for their pumps is one of the reasons I've considered them to be a solid option. Not that I've really needed much. I've replaced a few rubber bits, but honestly I think it's really only the dust covers I've felt like replacing so far. On the subject of valve tools: I discovered that my one multi tool that has a valve tool in the tire lever is problematic. I think it technically works, just not when you try to use it when the tube is attached to a wheel because the spokes obstruct you from turning it. You could rectify the problem by pulling the tube out and dealing with it before putting it back in, but if things have gone that wrong you probably aren't going to be in a good mood about doing that.
@@boredalreadywiththis some great points here Colin I really enjoyed reading it. I know exactly the older pumps you are talking about. I also know the feeling of doing something subconsciously to make it work, we've all been there! You are right about the clamp option limitations. You are certainly deciding which battle to have. For me the high pressure firing off the pump is most frustrating. I'm sure you could buy the new hose and use on your pump. May give you that security you need. One of my frustrations with multi tools for bikes is when they try and squeeze too many into the size of it, and it's not fit for purpose. What model have you got right now??
@@mammothjourneys I have a topeak hexus x. I've had various generations of that tool and they generally do a solid job. The tyre levers mostly work (I generally carry an extra pedros lever too for when you want that extra heft), and they have a good chain tool. I've even used them to true wheels on a ride. Some of the tools are very much a compromise you'd only want to use if you're forced to, but if not on this latest model, I think I've used the majority of the tools in those hexus generation tools. My chain tool pin died from lots of use on my first one. I find them so good I use them as *the* chain tool in all my maintenance. Having the 3 posts seems not to be as common as you'd hope in chain tools. I do carry quick links for anything >8 speed for attaching chains back together.
@@boredalreadywiththis a chain tool is a must on a multi tool I think. I've had to save mine and others with it, and surprised how well it works given the size of it. Happy to spend money on quality tools like this you know will bring you a return. Need to go remind myself what make and model mine is though!
I have the Lezyne grip drive hv which has basically the same design as this and the hose is exactly the same. I use presta valves. I've used the pump dozens of times and have yet to have this issue. 🤷♂
@@mammothjourneys the other thing that can make it less likely to unscrew the valve is to unscrew it from the pump body first. Doing that, there is also no need to press the release button.
@@fordbailey8173 I thought I had tried every permutation of what to take off when, but this makes sense as all the pressure will have released from the screw end of the main body. Do you still use this pump then? Have you lost any inner valve yet to it?
@@fordbailey8173 Do you know if other brands or models that have the hose have the same problem? I agree having the hose is good and if there was an alternative that didn't have the risk I would be really intereseted.
The same happened to me!!!! I felt like an idiot. The valve core always came out (whether I pressed the side button or not). I'm happy to hear it's a design issue.
Sorry to hear mate. Hopefully you weren't too far from home or had someone with you with another pump. You certainly aren't alone with this one! What pump did you go with instead so you don't have to use this one again?
@@mammothjourneys Funnily enough I was in the middle of a forest but there was a cafe which has a bike pump. Re:new pump... I'm cycling w/o backups... XD
@@anibalgonzalez7990 At least you got a bit of luck of where you had your puncture! The puncture Gods must have known I bought a new pump since this one as I haven't had to use it yet!
Hi Sam, sorry to hear you had the same frustrations as me on this. But at the same time reassuring that I'm not alone on this. Hope the next pump you had more luck with! 🤞
I only had the presta core issue once but then I mainly used Schrader valves. HOWEVER . . . . it's almost as annoying with Schrader because I'd frequently assemble it the wrong way around, which is my fault but still annoying. Overall I was never that impressed with this pump (bought it during lock down I think when alternatives were limited) and subsequently swapped it even though it is still in working order.
Richard your not doing anything wrong....however that pump is'nt either,you just need to snug up your tube cores with a valve core tool.I use and also carry on my rides a Park Tool VC-1 valve core tool and when ever I start using a new inner tube the first thing I do is just snug up the valve cores within the tube prior to it's installation.Also try attaching the pump's tube onto the inner tube first and then attach your pump to the tube installed.....just my tips for what they're worth.
Thanks mate some good suggestions here. Will give them a try and see how I get on. Fully expected some user error on this one! Cheers mate and happy riding 😀
In what world do you notice a soft tire, then "You remove the thing that's causing the puncture, such as a thorn, in the, ah, tire. You're pumping your inner tube back up, and when you've finished pumping, the inner tube and tire stays inflated and you're ready to continue on your ride..." Did you miss a critical part about changing the tube? At which point you're whingeing about having to tighten the valve core melts away. You've already pulled out your tube, inflator, tire, levers, and often times a multitool, removed the wheel, use tire levers to unmount the tire, pulled the dead tube out, inflated it until you can locate the puncture, find that same spot on your tire and checked for the embedded thorn, bit of wire, sharp rock, etc. and hopefully removed it, and then you can snug down the valve core on the new tube before slightly inflating that, installing it, re-seating the tire, inflating it, remounting the wheel, and packing everything up. Worst pump in the world? Because you're stroppy for one very easy extra move in, what? a dozen more complicated moves? I might want to take this one down. Also, those instructions: feel a soft tire, remove the offending thorn, pump it up, get back to riding. Those are not only silly instructions, they are worthy of contempt. Makes me wonder just how long you've been riding? The person following those instructions had better have home in sight-- and no steep descents on the path. How about a proper "Here's how to change a tube" video? Or just direct them to the 100's already out there?
Wow, there is a lot of energy here, I love it. This is the second comment to flag up I missed the step about changing the inner tube, simple lapse of concentration, but clearly the gist of my message wasn't lost, reassuring to know people are listening. You are right, there are lots of steps when changing a tyre which makes it frustrating. In my mind adding to that list seems illogical, when there are other options where you don't have to do it. Imagine never owning another bike pump and thinking the risk of removing your inner core was normal, and that you always had to the step of tightening it. Hopefully by flagging this up I can show people there are other options. Check out the other comments, I'm not alone here, which is encouraging. Happy riding Alan and hope it's puncture-free!
I love my Lezyne pump, never unscrewed the valve core. Just stop unscrewing the hose after it is off the valve stem for goodness sake, also nip up the core with the tool provided. The description in the vidoe for fixing a puncture will only work for tyres filled with sealant, otherwise you actually repaor the puncture with a new tube or patch!
Good to hear you aren't having the same luck as me. I presume it's the same model?? When you say stop unscreweing the hose after the valve stem, what's the other option?
@3:52 the hose is unscrewed from the stem but you keep turning it - just pull it off rather then continuing to completely unscrew the valve core! My pump is an more basic plastic handled version to be fair - I didn't see the benefit in paying more for a handle that feels less comfortable, harder to grip, and is more liable to paint scratches etc. But I think the same principle applies, make sure the valve core is torqued up more than the hose, you can also apply a bit of silicone grease to the gasket on the hose.
Oh I also found that the internals of the pump were pretty much unlubricated from the factory - and although it worked ok that way a bit of silicone grease on the o-ring helps it to run cooler and with less pumping force.
Had the exact same problem. In addition, the O ring on the base of the plunger keeps coming off, rendering the pump useless. But now I have no problems, I found the solution - the pump is now in the rubbish bin.
Ha ha this made me laugh a lot, thank you! Sorry to hear you suffered the same fate as many on this. Reassuring that it wasn't just me! What pump did you go for in the end?
Update!!!! Need to tighten with wrench the bottom part of Presto valve. Otherwise it will keep going to come out… After tightening it all worked well 👍
Hi Todd, sorry to hear you have become victim of this pump. I don't understand why they designed a pump where this is a risk. You'll see from some of the other comments people suggest ways to stop it, which is helpful, but as you don't need to do this with other pumps it seems like an unnecessary step to me. Hope you find an alternative that works a little easier!
@@mammothjourneys Yes- I did get a Barbieri - Ultralight Carbon Minipump and it works w/o the hassle of removing the core and is light yet still gets the job done. #pumps
Omg this happened to me on a 1000km Audax ride in middle of nowhere and I thought it was just me. That pump is coming off my bike asap and being replaced.
Ah no that sucks. What a worst time for it to happen. You are not alone, many have suffered the same fate. 100% replace, take away the stress and risk.
It is actually the worst and the best bike pump. I've had this pump for many years now. I upgraded from Lezyne Tech Drive HP which had a plastic (!) thread for attaching the hose that unsurprisingly worn out in no time and I had to bin the pump. Lezyne told me back then that I must have been too aggressive when threading the hose into pump. So I switched to a medium length Pressure Drive which is all metal suitable for aggressive people like me, and also invested in the pen gauge hose. Still had some annoying issues though. My old Tech Drive came with a rubber collar that stopped the handle from rattling and opening but the Pressure Drive didn't have it. Lezyne said they redesigned the handle and the stopper wasn't required any more. Well, I don't know about that, when I shake my Pressure Drive it rattles, when I use it with the recycled stopper from the old pump it is completely silent. Finally the troublesome flip chuck. Mine corroded and I think the o-ring fell out as the chuck would leak air. I wanted to buy another one but they didn't sell replacement chucks. Only after contacting the local distributor they were kind enough to send me a spare. So good luck to you if you need a new one. The replacement has corroded too but so far is still working fine. As for the issues with unscrewing of the valve core, I've been there many times and developed a technique to minimise this, whereby I unscrew the hose from the pump first (you have to do it later anyway) and then pull the chuck as soon as possible watching the core like a hawk making sure it doesn't unscrew first. Why did I say it was the best pump? Because there is no alternative, a hand pump that doesn't look ugly when carried attached to the bottle cage mount, that comes with a hose and a pen gauge, and makes it possible to go up to 100+psi. I thought the design of the horrible chuck was a necessity due to the limited storage space for the hose inside of the pump. Yet, Birzman managed to come up with apparently a much better push-in instead of screw-in design in their Velocity Apogee pump. But the pump sadly got discontinued and the new model comes with neither pressure gauge nor their superior chuck. So that only leaves the Pressure Drive...
This was such a great comment I loved it, thank you for taking the time to send it across. I find it hilarious how Lezyne accused you of being too aggressive with your pumping. For me robustness is key for any kit, so the fact they use that as an excuse is poor. Also with any brand not to offer the after support to help keep products going, and reduce waste, again is poor. Recently I contacted Wahoo for a replacement part, which I was happy to pay for, and they sent it free of charge. I admire your perseverance finding a technique that made this pump work, good on you. I'm sure there are other pumps out there which can get to 100+psi without the pitfalls of this Lezyne. So have you stuck with this pump then?
Well done Wahoo. I had a similar situation with The North Face when I accidentally damaged the belt buckle in my backpack and they just sent me a replacement free of charge. Very reassuring. The gauge in my Pressure Drive hose broke, the outer rubber split and the gauge doesn't work any more so I was looking around for alternatives but the only choice I see is the discontinued after-market Birzman. I'll try to get either that pump, as I'm curious how it performs in comparison, or a replacement pen gauge hose for my Lezyne. Incidentally, the tool that comes with the hose for tightening the core you showed in the video, I don't have it, so it must have been introduced later. I see this as part Lezyne's admission of the design flaw and part defensive move so they can always say it's your fault the core was not tightened enough if it popped out. That tool is better than nothing I guess although it now sticks out like a sore thumb. I'd personally not want to see it hanging on the pump but stashed away in the saddle bag. So yeah, despite the issues and subpar support I'll probably stay with my Pressure Drive in the end, as I like to have both the hose and the gauge, and that's the only product on the market which offers those in a sleek package. Also, now I finally have a spare chuck from that broken hose! But if you don't care about the looks much then check out Topeak Mini or Turbo Morph. I had the latter and found the fold-out stand pretty useless and the skinny handle not that comfortable but they do come with a hose, gauge and a trouble-free lock-on chuck.
@@placebythesea years ago I bought the Turbo Morph and it worked well, but it always seemed a little fragile. It never did break but I wouldn't have been surprised if it had. I've gone for a pocket rocket, it seems to do the job OK but I do miss the hose feature. I loved how analysis of Lezynes guilt in adding that core tightening tool, I never thought of it like that but it completely makes sense. The tightener is one the newer models of this pump. Good to see North Face also looking after their customers. Stuff like this just makes me pick that brand in the future. Why I would never get anything but an Osprey bag. Best of luck fixing the pressure drive, let me know how you get on, and any other cool kit suggestions. You certainly sound like you know how to pick decent products 👍
I'd agree that the removable valve stems have an influence. But if it wasn't the pumps fault, then this would happen with other pumps as well. Which I haven't had.
Good suggestion, hadn't thought of that. Although it's frustrating to have to add an extra element into the routine. But if makes it all work happy to try. Thanks NFC 👍👏
I can confirm that blue loctite solved the problem for me. Exact same pump, exact same problem with valve cores. Now I just dab some thread locker on the core after I add sealant. There is another problem with this pump. After pumping vigorously for several minutes, it can fail to recharge the cylinder on the return stroke. Instead of pulling in fresh air, it will create a vacuum and spring back to the collapsed position. This doesn't always happen. When it does, I stop and wait for the pump to cool off.
@@chrissanders4339 two votes for the loctite then - must be good! Now you mention about the pressure thing this makes complete sense. I have noticed this but couldn't figure out what was happening. Thanks for explaining it. Do you still use this pump then?
Similar experience. I came here to figure out what I was doing wrong. I use the Topeak pump on my dirtbike with schrader valves and never had an issue. Figured my issue was because I'm new to mountain biking and presta valves. I see a commenter suggested blue loctite; I'll try that. Thanks for the video!
I mean, Schrader is better anyway...I have never had any problem with them and if the inner tube has metal valve (or metal tubeless valves, which let more air through than presta), it is bombproof.
Yeah I'll be honest, as time passes I'm not sure the benefits of presta are that great for the vast majority of uses. Only perhaps road bike tyres but for a lot of riding I'm not sure what extra you get for a more complicated system. I could be converted!
@@mammothjourneys With Schrader, you can have rubber valves and those could be problematic. It is easy to cut them with the rim edge when you wiggle it around. Maybe thats why some people dont like them. But with a steel one, it is much better and the cost is almost the same.
I have a Lezyne floor pump and mini pump. Beautifully engineered and thoughtfully designed. If your valve core is coming out: 1. Tighten the valve core a little more than finger tight. There is a tool built into the pump. 2. Don't over tighten the chuck on the valve. Don't tighten until it stops, a few turns is all that is necessary. 3. Use the ABS button to bleed the pressure from hose before unscrewing from the valve. Even if you don't use a screw on chuck, presta valves can be delicate, they're soft and bend easily and therefore can break off if treated roughly.
Thanks Dan these are some good points. Being gentle with the presta valve is important for sure. Good to hear you are having a decent experience, and with the floor pump. 👍
I’m with you, it’s a terrible pump. Here’s how I fixed it though. Remove the hose from the pump and throw both the pump and hose in the bin. Use a Silca Tattico instead. Problem solved. 👍
@@mammothjourneysno worries, glad you got a chuckle out of it. In all seriousness though, no you don't have to tighten the valve core or hold your mouth a particular way with any other pump I've ever used. Period. Its just not a thing. I confess to having a Silca attraction. I bought a Silca track pump in the 80's and its still going strong. In recent years I've added the Hiro pump head and its easily the king of pump heads. Sure it costs as much as a small car (not really) but use it and you'll understand why. And in all those decades, I've never once lost a valve core for any reason or even had to tighten one. So they know a thing or two about inflating tires without removing the valve core. At some point for whatever reason I decided to buy the sexy and petite lezyne pump which worked out like a crazy girlfriend - looked good, caused anguish in use. Replaced it with the Tattico which while a significant investment puts air in the tire without fuss. It easily puts air in big gravel bike tires for extra win although I've bought a Gravelero for that bike now. Anyway the one pump and a handful of brackets means the Tattico is used on the whole fleet other than the gravel bike. The lezyne mini pump is sad and alone in the shed as a reminder of why you should never buy a terrible pump. A further development, I'm using a Ryobi battery powered inflator with the Hiro head now instead of a floor pump. It has a digital readout and is the future I tells you. Takes seconds to top off the tires before heading out without removing the valve cores. We live in amazing times. 😃
@@KeithHeinrich There were many parts of this reply which I loved. Firstly the sarcasm of the effect of what you do with your mouth on the impact of inflation. Secondly how long you have had the initial track pump, huge love of kit that lasts time. I've not heard of Ryobi for inflation before but it makes complete sense - genius! And finally, I hadn't heard of a Hiro pump head but the engineering on it looks immense. You have taught me so much in one comment! I've not got lost down a great rabbit hole on a world I didn't know I loved - thank you!
@@mammothjourneys the Silca Pista has been around since the 1950's. It features a leather plunger washer and parts made of metal including a push on chuck, the check valve and so on. The tube is said to be columbus steel, the same as used to make bicycles at the time. As a result, there's nothing to break or wear out really. Mine was acquired new in the 80's and was passed around before races putting air in countless tires over the years. The brass chuck made sense since stems for tubs were smooth so it slipped right on. Around 2018 maybe I bought back my old race bike and had it restored and had the bike shop refurbish the pump at the same time since you can still buy all the spares for them. As a surprise the bike shop had the pump finished the same as the bike. So now this fine heritage item with sentimental value still works as well as it ever did and looks great while doing it. This is why I think that there are many with a strong attachment to the Silca brand who for sure market on their heritage but take it seriously enough to build new products that are easy to use and perform. Expensive, but tremendous value at the same time. gallery.heinrich.id.au/bike-stuff/cycling-pics#gallery/88aa6a2cbb386d106d54de1c2bd6f966/6512

True, Lezyne design is rubbish. Had to use Lezyne pump on MTB marathon under pouring rain, and was "pleasently" suprised when Lezyne piece of crap did unscrew the valve.
Oh no that is tragic. Couldn't have happened at a worse time. Did you know there was this risk when you bought it? What a horrendous time to find out. Sorry to hear mate - what did you go for instead?
Now it's 2024 and it is still the world's worst and in the same time most expensive bike pump! Think about you are in the mountains and it's getting dark and you have to rely on this pump to get home. It's an absolute shame!
I have the same problem with this pump. No matter how tight you tighten a valve, this stupid pump will unscrew it anyway. This pump should be called “Frustration 3000”
@@mammothjourneys About the same as with the reviewed one. Sleeve not moving or very tight, grip of the chuck on the valve flaky, risk of losing the spring. On average, the whole procedure takes much longer than with a conventional chuck because of the frequent complications.
A bad workman always blames his tools. This is a well known issue which is addressed by countless cyclists over the last several decades, so look in the mirror and aware the person you seem the appropriate dimwit award of your choice.
Hey, I just wanted to thank you. In 2018, your review of Marin Four Corners helped me buy that bike and quit smoking for good. I went from 25 ciggies a day to zero and remain smoke free. Now I am getting a custom bike built for endurance rides. Thank you once again. may your channel grow by the thousands. :)
Wow this is amazing! I am so happy for you here and this made me smile so much. I hope the Four Corners treated you well. What have you got planned for the new bike? Well done on the lifestyle change, very impressive 👏💪
@@mammothjourneys I absolutely loved the bike. It is now without its shortcomings, of course, and maybe if i were to buy now I would choose Nicasio. But hell, that bike and thousands of miles covered on it have made me so much more tough. If i can can climb on that bike, every other bike will feel easy. The new bike is a hark back to old school: rim brakes, bar end shifters, all steel build and relatively lightweight (under 10 kilos). The only thing slightly modern would be tyre clearance which is for upto 35mm tires. I have never had a proper road bike so I thought why not start with something basic. Please keep up the good work, and interestingly, I was bout to buy the same effin pump!! glad I didn't, I will go for a Topeak now. :)
@@amitkumar-wj8gn That is very true, any future bike climbs will feel easy! What rides have you got planned with the new bike?
Yes I will continue releasing stuff and thank you for the kind words - glad you avoided this pump! I also went for a Topeak - keep it simple.
@@mammothjourneys mostly day long rides in the hills and maybe some randonneuring events. But i made sure there are no multiple mounts n all, wanted a clean-lookin bike. Can always add a frame bag and a handlebar bag if i feel like. Marin FC was a lot of things, but for covering miles in a day, not so much. Hence the decision to get a good ol road bike.
@@amitkumar-wj8gn Nice thinking and this sounds like a great adventure. Remind me again where you are riding? Send over a pic of the new bike to my instagram - interested to see what it looks like
So would you suggest that pump for Schrader valves exclusively? Despite the issue you mentioned, it works good?
I'm interested to use it for 650b tires (47-584), Schrader valves, 70 PSI max pressure (I only inflate them up 60 PSI max).
I've used it on Schrader with no issues at all. It being a screw fit means it's secure. So if it's in your price point then go for it!
For that PSI you'll probably be able to hit it with this pump. I hope that helps 👍
@@mammothjourneys Yeah that was helpful, thank you.
I've had this issue with mine in the past. I've learned to tighten the valve cores down well, and not overtighten the hose when attaching it to the valve. I still agree with you that you shouldn't have to do this. I've not had the same issue with their Micro Floor drive pump, even though it also screws onto the presta valve. I've wondered if maybe a bit of oil or a thin layer of petroleum jelly on the inside of the pump would help. I assume that the issue is that whatever rubber they are using to seal against the valve is grabbing the valve too tightly
Reassuring to know others have had the same issue. I did try not screwing the hose as much and this certainly helped. I always felt a level of anxiety when I was removing the hose, never fun.
I've heard their drive pump is really good, perhaps I just need to try some other pieces of their kit.
Criticism is spot on. I’ve used this pump for years and have a valve core tightener in my Lezyne multi tool unit. The pump is the only one that fits presta short valve stems so I’ve learned to live with it.
Thanks for reassurance here. Have you been tempted away from this for one that doesn't hold that risk??
im wondering if an adapter presta to shradder would help solve the issue ?
As in on the inner tube valve? That hasn't been mentioned and is not a bad suggestion as it's small. Would you still be able to get the pressure you want?
i've tried the SPORT DRIVE HV (base model) but to get 4 bar it's so hard ! .. I don't really know if the other expensive pumps do a better job because are still 6.2bar max..
Afraid I can't help with that one. I never get ones that are too expensive. I concede it'll never get the same pressure as a track pump, although I'm sure there are ones that can.
Good info. Thnx
Concur. Many thanks for your honesty and wisdom.
Thanks mate, glad you agree! Happy riding 😁
Did you try using the presta (French valve) to Auto valve adapter and then just use the schrader side of the pump?
I haven't tried this but someone else suggested this as well, which seems like it would work. But by the time I got told about this I'd already bought another pump. When you give it a go let me know how you get on.
I've had this same problem with Lezyne when unscrewing the hose, but it happened after not using the pump for a long time and an easy fix was using a bit of Lithium grease on the nosel and it hasn't failed since, "best" mini-pump ever ;)
That's not a bad idea, do you still get a good fit for the hose to attach? Ha ha nice upgrade in title as well!
@@mammothjourneys still works 2 or 3 summers later
@@rgpeters that's what you want. Good to hear mate, I'll check it out. Do you apply to grease at home and leave it as is, or take the grease on a ride with you?
Wish I had seen this video a couple of months ago, before buying this piece of 'expensive' junk.
My solution is to always carry a presta to schreader adapter, and never mess with the presta core again.
Cheers from Argentina!
Sorry to hear you have had the same experience to me here mate.
There are a few other suggestions from users here who have found ways to use it which could help. Hopefully you can then get the most out of the expensive junk!
Agree with you 100% about the Lezyne being the world’s worst pump. Actually, it’s 200% for me, because I purchased 2 pumps for my 2 bikes 🤪
Ha ha the same model lezyne for both??!
I presume you had a similar experience then. Glad it wasn't just me!
Same happened to me as well. I was just furies. Expensive "high quality" pump failed me in a critical moment. I ditched cheap 3 euro pump because of my vanity. Fortunately I had some zip ties along to attatch the pump hose to the spoke.
Oh no mate that sucks.
Sorry to hear you had the same experience. I was so annoyed when it happened and thought how stupid it was. Have you decided on an alternative pump?
Where do you do your riding?
I was about ready to order one. Thanks. You just help me to saved my hard earned money. 😁
No problem at all, glad it was helpful. A few of the comments on here as well show it's not unique to me this experience. Which pump did you end up going with instead?
Same here, off to look for a different model...any recommendations @mammothjourneys?
I unscrew the flexible hose from the pump before unscrewing the flexible hose from the valve. Seems to work fine.
Nice, will give it a go - cheers for the suggestion. Glad to hear you are having better luck with it as well 👍
Here's what I do. 1. Screw hose to valve. 2. Screw pump to hose. 3. Pump up tire. 4. Unscrew pump from hose 5. Unscrew hose from valve. I don't touch the magic button. I use dt swiss valves (dt swiss rims). Not sure if the valve type would make any difference. Gut tells me no. Oh, one thing I do is I practice taking tire off, removing tubeless valve from rim, inserting tube, reinstall tire and pump up. I do this in a nice, dry home setting. Usually sealant takes care of punctures but I have had the situation where I had a sliced tire. So I put a dollar bill into the tire and add the tube. Been lucky with valve cores. Haven't had one unscrew on me yet. But it could happen.
Lost count of how many times I've let my buddies use this exact pump when their crappy blackburns couldn't get the job done or when their CO2 chucks froze open and emptied without seating on the valve, but yeah sure buddy, this is the "worlds worst bike pump"
Good to hear you've had a good experience and you've got to help others out - not all heroes wear capes! Quite a few others having similar experience to me, but equal number have yours, if I made a product I'd want to get higher than a 50% success rate. Anyways, happy riding mate and glad it's all working for you 👍
Happened to me on Saturday on a cold rainy day, pulled the core right out. Also pump threw the o-ring off, so I couldn't even pump it back up! Luckily we have just finished our coffee shop stop and a kind gentleman driving by happened to see us struggling and had a floor pump! So now I'm ordering a new o-ring kit and some silicone grease to hopefully fix the pump. Would not have bought 2 of these pumps if I had known of this issue!
Oh no mate this is an absolute nightmare. Sorry to hear you are experiencing the same as few people on here. Some others users suggested some locktite which may work, perhaps something to try. Best of luck with the fix!
You're doing it wrong. Blue loctite on the valve core. Only screw on hose enough so air can pass. No problem!
Hi Tekjim, you are the second person to recommend loctite, which would certainly work. Although this is an extra step you don't have to do with other pumps. If you were on a ride with mates or helping a stranger with a puncture, and needed to use your pump, you rely they have used loctite to have that assurance. I did try as well not to tighten too much onto the valve but found this made it less secure - but this did help things. Both are good suggestions but both are steps you don't need to do for other pumps. I presume you have a good experience with this pump which is ace to hear - appreciate the advice it's always helpful 😀
Really? You have to use loctite so you can use this pump 😂 Clearly the pump is not fit for purpose. Get a pump that is fit for purpose.
@@dalj4362 Completely agree, you shouldn't have to do this.
Explain to me how does removing a thorn causing a puncture is going to solve the problem without patching or replacing your inner tire by just pumping some more air in ? you won't get far like this or what am i missing :-) ?
Or is he talking about tubeless tires or tires with sealant inside ?
Ha ha good point, should have said put in a new inner tube or patch up your old one before starting the fun and games of pumping.
@@Buzze1985 just tried to make the point of removing the thing that caused the puncture to the inner tube. Nothing on the tubeless front on this video. Hope that helps 👍
I have one of this pump, I don't like it either cause it's just too small and too slow. After I tried it once I switched to CO2. Just one thing, why do you use these detarchable valve core inner tube... You can use those non-removable valve inner tube that won't have this stupid problem..
Completely agree it would solve the problem. My tyres already had those types of tubes in, but since this pump when I replace them I choose the ones that can't be removed.
CO2 is a great option, so much quicker.
Bought one last month while on vacation. Rubber hose part has has metal fitting which screws into the plastic threads on the pump body. Needless to say I didn't use the pump until we travelled on, only to discover the cheap plastic threads are stripped.
Super expensive pump already, but now have to pay for shipping to send it back to where we bought it.
Oh no mate that is some rotten luck. Clearly someone not doing their QC checks! Hope you got your money back alright in the end. What did you go for in the end?
@@mammothjourneys Seems many products are "rotten luck" these days the way they build stuff now. I can name at least 6 overpriced items that were awful quality I purchased/replaced over the last year: that pump, eye glasses after one year the scratch proof coating began to separate from the lens, a short lived dishwasher, an outdoor light that leaks water into it, a very expensive mountain bike with 2 recalls and other horrid cheap parts on it, car tires that took no time to wear out, a rear view mirror for my car that falls off because the windshield replacers didn't use the correct mount. It's not just bad luck; it is modern day get rich quicker engineering scams. Have a good one!
Just had the exact same issue today on my ride. Pouring with rain when my puncture occurred. Left frustrated that i could for some unexplainable reason not get my new tyre pumped up fully as it would release the air. Tried the button and it was hopeless. So just got home and after a shower will order a different pump.
Oh Pala that sucks. I know your pain! What pump have you got in mind?
The worst time to get a puncture is in the rain, and it's at that moment you want your kit to perform.
Why would they design a pump which doesn't work?!
Which portable bike pump do you recommend then? I haven't used one before so I have no clue.
After the fail I had with this one I went for the Topeak Pocket Rocket mini pump. It seems reasonable so far but ironically since I bought it not had a puncture out on the road - can you believe it! Have you bought the Lezyne pump? If so a few people in the comments have suggested some options to make it work, have a read and I am sure it will help. If not, which pumps were on your shortlist?
@@mammothjourneys Thank you for the reply. I actually tried out Topeak's mountain morph pump at the shop today. I stopped forcing it once there is resistance in the cylinder. Do you force it further to put more air into the tires or is that a bad idea?
@@user-yu4kv4eb9h without a pressure gauge on the pump it's hard to know the true pressure in the tyres. With hand held pumps it's generally tough to over inflate. As they would be mostly used to get you home, simply squeeze the tyre by the side and compare with the other tyre. You don't want to overinflate as that runs the risk of bursting the inner tube. It would be helpful to have one pump at home with a pressure guage to reduce this risk. I'm not too bothered on my small hand held ones as I only use this in emergencies and I know I'll get tired or won't have the strength to over inflate when using it after repairing a puncture. What type of valve and tyre are you using on your bike?
@@mammothjourneysI have Schrader. Not sure about the tyre.
@@user-yu4kv4eb9h I have actually bought this pump years ago. Incredibly practical to use it you have the space to carry it. The little foot stand is so helpful. Schrader generally have a lower pressure than presta, so just keep an eye on things when it becomes tough. Squeeze the tyre wall inwards and compare it to the other tyre. Once you get close to what the other one feels like stop. Hope that helps, happy riding!
You arent alone. I just had this happen in the mountains. Took over 45 min to fix and pumping up the tire 3 times in sub 40 F weather as it was getting dark. Nearly got stranded. Trying to figure out how to make this work. My bike shop mechanic said he has broken a valve a couple with regular hand pumps. So I'm not even sure if there is a good option other than CO2 at this point. Id like to get enough pressure to continue my ride as planned without a concern
Wowsers this is a miserable experience. Sorry to hear mate. When mine failed in the dark and raining all my toys were thrown out of the pram, I'm sure it was the same for you when it was that cold!
Where was this?
Did the bike shop recommend any suitable hand pump?
@@mammothjourneys Mountains in Southern California. And no unfortunately, the mechanic said he prefers the pumps with a hose attachment. Ones without you have to brace and can snap the valve. So both are flawed. Like someone suggested here Lezyne actually recommends a bit of Loctite on the valve. So I suppose I could add that to my spare tubes and make sure they are nice and tight. Other thought is maybe a small amount of grease to valve stem threads on spare tubes. I've also noticed comments saying 3 or 4 attempts to get it off. Maybe threading the hose off and on a few times may help. In either case I added a couple extra valves and a valve tool to my bag just in case.
@@starlitshadows interesting I've never had an issue with the normal hose attachment. All the suggestions on how to make it work I'm sure are effective, but an extra hassle you don't need with a normal attachment. Very jealous of south California, bet it's some epic riding there! What bike you got?
I totally agree with you that Lezyne, should have done a better job in testing their product. I also had a bad experience with the Lezyne Pocket HP when I had a flat tire towards the end of the ride and a fellow cyclist stopped to help me and you probably guessed he had that pocket pump and it happened as you’ve described in your video, twice .. I own several mini-size and a few floor pumps and I’m on the market for another one, something compact and reliable. That’s how I came across your video. I haven’t read all the comments, so I apologize if someone else has mentioned this or a similar solution. In, fact, I just tried this with a different pump just a few minutes ago, and it seems to work. I have a Schader to Presta valve adapter, which its weight is negligible, and I screw it on my Presta valve and pumped air into the tire effortlessly. So if people don’t mind carrying a small aluminum adapter, that may be the best course of action and you still keep your pump. In fact, you tighten up the inner core of the Presta valve once you are done and you can place the Schrader back on and live it there, so you won't forget it. Not an ideal situation, and does not excuse the manufacturer’s product flows, but you get to use your pump effectively since you have already made the investment. Just a thought..
Sucks to hear you had a bad experience with the pump. Twice is a bit brutal as well! No-one has recommended the adaptor yet which is a good option - how much did that thing cost? At least you don't have to shell out on a new pump which is good.
1) Tighten the valve core. This doesn't have to be super tight, but it should be snug. Even new tubes will likely need this done. You can use the tool on top of the chuck to do this, as your fingers likely do not have enough grip. To use the tool on the ABS-1 Pro, the plunger for the presta valve needs to be completely open, then the tool should be able to reach the flats on the valve core.
2) Do not over tighten the chuck on the tire valve. The chuck only needs the leading o-ring to touch where the valve core and valve stem meet. This will only be a few turns after the threads all engage. Threading the chuck on "until it stops" will possibly jam the valve core or plunger in the body of the chuck.
3) Use the ABS button on the chuck to bleed pressure. This removes the pressure from the hose, which will lower the friction on the valve core threads to make unthreading easier.
Thank you Dan. I'll reply to the other comment on this you made so it's one place - cheers mate
I hate this pump because I wasn't paying attention and accidentally bought the HP instead of the HV to pump up 29 x 2.6 tires. I've never used the button and haven't pulled out any cores, but I regularly add tire sealant and probably over tighten the cores, plus the sealant probably works like loctite.
The pump gets very hot pumping up a big tire and the handle isn't very comfortable. I like the way the hose attaches to the tire because it provides different ergonomic options for pumping and it doesn't feel like I could accidentally break the valve stem.
I just purchased the HV drive, hopefully I don't lose any valve cores, but I'm glad I know this issue exists and might add an extra core to my kit.
What might help is loctite which a few others have suggested in the comments, but not sure what effect adding sealant will have on that. Best of luck with it mate and hope this was helpful 👍
Why do we use removable presta valve cores on tubes?
This is something I've learned from buying this pump. I've made sure I don't have this type moving forward - obviously needed one for the video!
Because people with deep rims use valve extenders and because presto valve cores occasionally break off or suffer irreparable damage, while the rest of the tube remains perfectly intact (so it's thus convenient to just replace the valve core)
I had the same issue with the pump pulling out that piece that releases all the air, had to call someone to pick me up lol
Sorry to hear mate, that sucks. If you check out a few comments there are some suggestions which may help.
And which one are you using now
Topeak Pocket Rocket in the end. Since I've bought it, I've had zero punctures! 😂
Damn, I had 5 similar pumps for the last 6+ years. Never had an issue like yours once!
You had 5 similar pumps over 6 years? 🤔🤔 What were you doing where you had a turnover of almost 1 pump a year? I'd be questioning the quality. Happy riding mate 😁
4 kids and a wife. Your mind slipped fast without asking!
@@aaronmosser 😂😂 fair play. Happy riding mate
Always happy riding!
Definitely a no-brainer bike pump--easy to use.
Good to hear the other side of experiences here. A few have come up and said they've had no issues with it which is ace. Clearly me being a bit simple!
Just bought the Lezyne Micro Floor Drive HV for my fat bike. I hope it lives up to the positive reviews. It has a longer hose than yours but now I'm starting to worry.
From what others have said I don't think it will. Their floor/track pumps are all good. For what it's worth the craftsmanship of the product is good, so I am sure your pump will be ace. Let us know how you get on.
Definitely has a learning curve , but once you’ve figured it out it’s bang on
Yeah this seems the case from a few replies. I'm certainly not on my own with my experiences, but there are a few ways to make it work. Did you stick with it then and happy using it?
Never happened to me. I used to work in a bike shop where I had to pump thousands of bikes with Lezyne floor pump and NEVER remove the inner core of the valve, also my hand pump is Lezyne for more than 10 years. I had tens of flats and my pump was always helpful. I think this is just user error. Here we say "both hands are left".
Hi Nooski, Glad to hear you haven't had the same issues as I did, or some others who have left comments. Was the track pump you use a screw attachment or with the lever? My track pump is a lever and never had this problem. I presume your hand pump is the same model with the screw attachment. Do you get a better performance than a lever attachment type pump? I wonder if you did if it's worth the risk should the valve ever be screwed out? Although I can't deny it's user error! Love the saying as well.
@@mammothjourneys Hello, yes, older gold screw in type on floor pump. I have pocket drive hand pump with the same hose, it's just a bit shorter. It's important to release air from the hose bit you have mentioned this. Also from my tubular experience I have valve core tool in my wallet all the time but never really use it.
@@nooski_Watches-ik9nr It's so interesting how different the experiences people are having with this pump. Certain valves, and using a core tool to tighten them certainly helps, along with the air release from the hose. I did have occasions where it worked drama free, which perhaps made it more annoying and confusing when it didn't work! Glad to hear it worked though for you and the ride carried on!
That was a really interesting review. I didn't realise that was what that button was for. I'd heard of that sort of thing happening so I don't think you're alone. I guess I've been relatively lucky. Mine is old enough to predate the button and I'd never even realised they had a version that had the valve core tool either. The other night I actually managed to do that valve unscrewing trick by taking off a dust cap (no pump attached) and it made me realise I didn't have any useful tightening tools. I personally haven't had any issues with presta valves doing that with my lezyne, but I can't explain why.
I don't think you're wrong with your general conclusions, although this is my favourite pump 😂. I suspect with modern materials if you buy a decent pump it ought to be good no matter what it's made of. And there are really good pumps with clamps instead of screw on if you get on better with them. I would definitely stick with a hose. That is definitely the one key feature I'd say everyone should be looking for in their pumps. No hose is my kryptonite when it comes to pumps.
Hi Colin, thanks for your insight here that's really helpful. Interesting you had this happen simply with your dust cap. I presume you're on the hunt now for a tightening tool to keep at home or put in your saddle bag??? I'm glad to hear though you are having a good time with the pump, I really wouldn't want anyone else to have the frustrtion I am having. I do believe this is massively 'user error'!
Thinking about the technique that I'm relatively unconsciously applying I think what I aim to do is ensure that the hose is perpendicular to the valve at the point it contacts the valve. I had lots of experience growing up using those old really long old fashioned type pumps that used to dominate cycling and learned that was ideal back then. Perhaps I had all my failures back then before I even saw a lezyne and so now largely I instinctively have a technique that minimises the chance of failures. Of course perhaps it's something else I'm doing even more unconsciously.
I guess the failure modes are the interesting point. With the threaded sort you mostly have unthreading the core on a presta. I guess if you have more angular force on the hose then it might rub that core more and be more likely to undo it. If it's loose you may well catch it anyway.
With the clamps the failure modes I've seen with presta are
a) failing to get air in because the valve sticks (that seems to be resolvable by tweaking the valve before attaching, letting a little air out, ensuring it's not going to stick - this might happen with a threaded one too? Perhaps I'm mostly only using my threaded one from a flat tire so I notice it less with that?
b) not having a secure enough connection to the valve so it blows off under pressure.
c) possibly mangling the sticking out part of the valve if you're not careful - this one might be common to both types of attachment?
I think bad experiences with clamps on small pumps without hoses may have made me more biased against the clamps. Threads I love the security that once attached it won't come off, and I've generally found it simple to attach and remove.
I do use clamps with track stand pumps, and I have over the years learned how to deal with most of the failure modes. Honestly I don't think either way is perfect. I guess it depends on preference. The clamp probably has a less severe failure mode and is more intuitive, but I have had times where I've definitely been very frustrated with a clamped pump at times.
I have found some of those tiny valve tools to carry around, but I'm wondering if I should get one of those hoses that came with your pump. My guess is that your problem isn't isolated because it seems that over the years Lezyne have been adding features that help to deal with it. First the button to release pressure, then the core tightening tool. The fact you can get spares for their pumps is one of the reasons I've considered them to be a solid option. Not that I've really needed much. I've replaced a few rubber bits, but honestly I think it's really only the dust covers I've felt like replacing so far.
On the subject of valve tools: I discovered that my one multi tool that has a valve tool in the tire lever is problematic. I think it technically works, just not when you try to use it when the tube is attached to a wheel because the spokes obstruct you from turning it. You could rectify the problem by pulling the tube out and dealing with it before putting it back in, but if things have gone that wrong you probably aren't going to be in a good mood about doing that.
@@boredalreadywiththis some great points here Colin I really enjoyed reading it.
I know exactly the older pumps you are talking about. I also know the feeling of doing something subconsciously to make it work, we've all been there!
You are right about the clamp option limitations. You are certainly deciding which battle to have. For me the high pressure firing off the pump is most frustrating.
I'm sure you could buy the new hose and use on your pump. May give you that security you need.
One of my frustrations with multi tools for bikes is when they try and squeeze too many into the size of it, and it's not fit for purpose.
What model have you got right now??
@@mammothjourneys I have a topeak hexus x. I've had various generations of that tool and they generally do a solid job. The tyre levers mostly work (I generally carry an extra pedros lever too for when you want that extra heft), and they have a good chain tool. I've even used them to true wheels on a ride. Some of the tools are very much a compromise you'd only want to use if you're forced to, but if not on this latest model, I think I've used the majority of the tools in those hexus generation tools. My chain tool pin died from lots of use on my first one. I find them so good I use them as *the* chain tool in all my maintenance. Having the 3 posts seems not to be as common as you'd hope in chain tools. I do carry quick links for anything >8 speed for attaching chains back together.
@@boredalreadywiththis a chain tool is a must on a multi tool I think. I've had to save mine and others with it, and surprised how well it works given the size of it. Happy to spend money on quality tools like this you know will bring you a return. Need to go remind myself what make and model mine is though!
I have the Lezyne grip drive hv which has basically the same design as this and the hose is exactly the same. I use presta valves. I've used the pump dozens of times and have yet to have this issue. 🤷♂
That's ace. Clearly more competent than me 😂 Few of the comments have given suggestions which have been helpful. Happy riding 😀
I have that pump. It helps to pull harder as you unscrew the hose.
Interesting, I wouldn't have guessed that. I would have thought that would make it worse....unless this is a windup! 😂😂
@@mammothjourneys the other thing that can make it less likely to unscrew the valve is to unscrew it from the pump body first. Doing that, there is also no need to press the release button.
@@fordbailey8173 I thought I had tried every permutation of what to take off when, but this makes sense as all the pressure will have released from the screw end of the main body. Do you still use this pump then? Have you lost any inner valve yet to it?
@@mammothjourneys I used it yesterday. I had a valve unscrew once, but I saw what was happening. I still like having the hose.
@@fordbailey8173 Do you know if other brands or models that have the hose have the same problem? I agree having the hose is good and if there was an alternative that didn't have the risk I would be really intereseted.
The same happened to me!!!! I felt like an idiot. The valve core always came out (whether I pressed the side button or not).
I'm happy to hear it's a design issue.
Sorry to hear mate. Hopefully you weren't too far from home or had someone with you with another pump. You certainly aren't alone with this one! What pump did you go with instead so you don't have to use this one again?
@@mammothjourneys Funnily enough I was in the middle of a forest but there was a cafe which has a bike pump. Re:new pump... I'm cycling w/o backups... XD
@@anibalgonzalez7990 At least you got a bit of luck of where you had your puncture! The puncture Gods must have known I bought a new pump since this one as I haven't had to use it yet!
@@mammothjourneys hahaha
Same thing happened to me, multiple times, despite doing the fiddly pre-tightening move. Zero stars as a presta pump!
Hi Sam, sorry to hear you had the same frustrations as me on this. But at the same time reassuring that I'm not alone on this. Hope the next pump you had more luck with! 🤞
I only had the presta core issue once but then I mainly used Schrader valves. HOWEVER . . . . it's almost as annoying with Schrader because I'd frequently assemble it the wrong way around, which is my fault but still annoying. Overall I was never that impressed with this pump (bought it during lock down I think when alternatives were limited) and subsequently swapped it even though it is still in working order.
Interesting a Schrader user also didn't like it. Sorry to hear you had the same experience, what did you go for in the end?
I had the same problem but solved it with a different inner tube with a solid core.
Good to hear. Yeah a solid core would solve all this, glad it's working 👍
Well you can still use schreder valve. Btw. I use adapter for my Presta valves. It’s simple and not so heavy solution.
Yeah someone else has gone this route with good effect, clever thinking 💪😁
Richard your not doing anything wrong....however that pump is'nt either,you just need to snug up your tube cores with a valve core tool.I use and also carry on my rides a Park Tool VC-1 valve core tool and when ever I start using a new inner tube the first thing I do is just snug up the valve cores within the tube prior to it's installation.Also try attaching the pump's tube onto the inner tube first and then attach your pump to the tube installed.....just my tips for what they're worth.
Thanks mate some good suggestions here. Will give them a try and see how I get on. Fully expected some user error on this one! Cheers mate and happy riding 😀
In what world do you notice a soft tire, then "You remove the thing that's causing the puncture, such as a thorn, in the, ah, tire. You're pumping your inner tube back up, and when you've finished pumping, the inner tube and tire stays inflated and you're ready to continue on your ride..."
Did you miss a critical part about changing the tube? At which point you're whingeing about having to tighten the valve core melts away. You've already pulled out your tube, inflator, tire, levers, and often times a multitool, removed the wheel, use tire levers to unmount the tire, pulled the dead tube out, inflated it until you can locate the puncture, find that same spot on your tire and checked for the embedded thorn, bit of wire, sharp rock, etc. and hopefully removed it, and then you can snug down the valve core on the new tube before slightly inflating that, installing it, re-seating the tire, inflating it, remounting the wheel, and packing everything up.
Worst pump in the world? Because you're stroppy for one very easy extra move in, what? a dozen more complicated moves? I might want to take this one down.
Also, those instructions: feel a soft tire, remove the offending thorn, pump it up, get back to riding. Those are not only silly instructions, they are worthy of contempt. Makes me wonder just how long you've been riding? The person following those instructions had better have home in sight-- and no steep descents on the path.
How about a proper "Here's how to change a tube" video? Or just direct them to the 100's already out there?
Wow, there is a lot of energy here, I love it.
This is the second comment to flag up I missed the step about changing the inner tube, simple lapse of concentration, but clearly the gist of my message wasn't lost, reassuring to know people are listening.
You are right, there are lots of steps when changing a tyre which makes it frustrating. In my mind adding to that list seems illogical, when there are other options where you don't have to do it. Imagine never owning another bike pump and thinking the risk of removing your inner core was normal, and that you always had to the step of tightening it. Hopefully by flagging this up I can show people there are other options. Check out the other comments, I'm not alone here, which is encouraging.
Happy riding Alan and hope it's puncture-free!
I love my Lezyne pump, never unscrewed the valve core. Just stop unscrewing the hose after it is off the valve stem for goodness sake, also nip up the core with the tool provided.
The description in the vidoe for fixing a puncture will only work for tyres filled with sealant, otherwise you actually repaor the puncture with a new tube or patch!
Good to hear you aren't having the same luck as me. I presume it's the same model??
When you say stop unscreweing the hose after the valve stem, what's the other option?
@3:52 the hose is unscrewed from the stem but you keep turning it - just pull it off rather then continuing to completely unscrew the valve core!
My pump is an more basic plastic handled version to be fair - I didn't see the benefit in paying more for a handle that feels less comfortable, harder to grip, and is more liable to paint scratches etc. But I think the same principle applies, make sure the valve core is torqued up more than the hose, you can also apply a bit of silicone grease to the gasket on the hose.
Oh I also found that the internals of the pump were pretty much unlubricated from the factory - and although it worked ok that way a bit of silicone grease on the o-ring helps it to run cooler and with less pumping force.
@@Twisty1024 ah OK I'll give that a go thanks for the suggestion. Makes sense and hopefully it sorts the problem. Cheers mate 👍
@@Twisty1024 the lubrication is a great idea for all pumps, nice thinking!
Had the exact same problem. In addition, the O ring on the base of the plunger keeps coming off, rendering the pump useless. But now I have no problems, I found the solution - the pump is now in the rubbish bin.
Ha ha this made me laugh a lot, thank you! Sorry to hear you suffered the same fate as many on this. Reassuring that it wasn't just me! What pump did you go for in the end?
Topeak race rocket - not used it yet, but it has to be better than the Lezyne.@@mammothjourneys
Woke up at 5am for a ride now is 9am still trying to understand how it works 🤦
7 times already getting start from beginning 😭
Oh no that is not a good start 😩 Hopefully you figured it out, or have bought a replacement pump! 😂
Update!!!! Need to tighten with wrench the bottom part of Presto valve. Otherwise it will keep going to come out…
After tightening it all worked well 👍
@@Dan_Jaden good to hear you got it sorted in the end. Some others here have commented about locktite which may help as well. Happy riding 😀
I’ve never had a pump do this before but first time I used this pump, it pulled the core out. So stupid. It happened multiple times
Hi Todd, sorry to hear you have become victim of this pump. I don't understand why they designed a pump where this is a risk. You'll see from some of the other comments people suggest ways to stop it, which is helpful, but as you don't need to do this with other pumps it seems like an unnecessary step to me. Hope you find an alternative that works a little easier!
Same thing happened to me! Got stranded since I didn't have a valve core tool and had to call for a lift :- (
Sorry to hear mate that sucks. Have you replaced the pump with another one yet?
@@mammothjourneys Yes- I did get a Barbieri - Ultralight Carbon Minipump and it works w/o the hassle of removing the core and is light yet still gets the job done.

@@davepenegar8789 ah nice choice. Will check it out. Can you get good pressure with it?
@@mammothjourneys Good enough to finish a ride-80psi is doable. I think they company calls them the NUDA or Nana now and have seem em on sale.
Omg this happened to me on a 1000km Audax ride in middle of nowhere and I thought it was just me. That pump is coming off my bike asap and being replaced.
Ah no that sucks. What a worst time for it to happen. You are not alone, many have suffered the same fate. 100% replace, take away the stress and risk.
Im having no issues with the 4 different ones that I own. Gotta hold your tongue just right😊
Ha ha this made me laugh, I like it! 😂
It is actually the worst and the best bike pump. I've had this pump for many years now. I upgraded from Lezyne Tech Drive HP which had a plastic (!) thread for attaching the hose that unsurprisingly worn out in no time and I had to bin the pump. Lezyne told me back then that I must have been too aggressive when threading the hose into pump.
So I switched to a medium length Pressure Drive which is all metal suitable for aggressive people like me, and also invested in the pen gauge hose. Still had some annoying issues though. My old Tech Drive came with a rubber collar that stopped the handle from rattling and opening but the Pressure Drive didn't have it. Lezyne said they redesigned the handle and the stopper wasn't required any more. Well, I don't know about that, when I shake my Pressure Drive it rattles, when I use it with the recycled stopper from the old pump it is completely silent.
Finally the troublesome flip chuck. Mine corroded and I think the o-ring fell out as the chuck would leak air. I wanted to buy another one but they didn't sell replacement chucks. Only after contacting the local distributor they were kind enough to send me a spare. So good luck to you if you need a new one. The replacement has corroded too but so far is still working fine.
As for the issues with unscrewing of the valve core, I've been there many times and developed a technique to minimise this, whereby I unscrew the hose from the pump first (you have to do it later anyway) and then pull the chuck as soon as possible watching the core like a hawk making sure it doesn't unscrew first.
Why did I say it was the best pump? Because there is no alternative, a hand pump that doesn't look ugly when carried attached to the bottle cage mount, that comes with a hose and a pen gauge, and makes it possible to go up to 100+psi.
I thought the design of the horrible chuck was a necessity due to the limited storage space for the hose inside of the pump. Yet, Birzman managed to come up with apparently a much better push-in instead of screw-in design in their Velocity Apogee pump. But the pump sadly got discontinued and the new model comes with neither pressure gauge nor their superior chuck. So that only leaves the Pressure Drive...
This was such a great comment I loved it, thank you for taking the time to send it across. I find it hilarious how Lezyne accused you of being too aggressive with your pumping. For me robustness is key for any kit, so the fact they use that as an excuse is poor. Also with any brand not to offer the after support to help keep products going, and reduce waste, again is poor. Recently I contacted Wahoo for a replacement part, which I was happy to pay for, and they sent it free of charge. I admire your perseverance finding a technique that made this pump work, good on you. I'm sure there are other pumps out there which can get to 100+psi without the pitfalls of this Lezyne.
So have you stuck with this pump then?
Well done Wahoo. I had a similar situation with The North Face when I accidentally damaged the belt buckle in my backpack and they just sent me a replacement free of charge. Very reassuring.
The gauge in my Pressure Drive hose broke, the outer rubber split and the gauge doesn't work any more so I was looking around for alternatives but the only choice I see is the discontinued after-market Birzman. I'll try to get either that pump, as I'm curious how it performs in comparison, or a replacement pen gauge hose for my Lezyne.
Incidentally, the tool that comes with the hose for tightening the core you showed in the video, I don't have it, so it must have been introduced later. I see this as part Lezyne's admission of the design flaw and part defensive move so they can always say it's your fault the core was not tightened enough if it popped out. That tool is better than nothing I guess although it now sticks out like a sore thumb. I'd personally not want to see it hanging on the pump but stashed away in the saddle bag.
So yeah, despite the issues and subpar support I'll probably stay with my Pressure Drive in the end, as I like to have both the hose and the gauge, and that's the only product on the market which offers those in a sleek package. Also, now I finally have a spare chuck from that broken hose!
But if you don't care about the looks much then check out Topeak Mini or Turbo Morph. I had the latter and found the fold-out stand pretty useless and the skinny handle not that comfortable but they do come with a hose, gauge and a trouble-free lock-on chuck.
@@placebythesea years ago I bought the Turbo Morph and it worked well, but it always seemed a little fragile. It never did break but I wouldn't have been surprised if it had.
I've gone for a pocket rocket, it seems to do the job OK but I do miss the hose feature.
I loved how analysis of Lezynes guilt in adding that core tightening tool, I never thought of it like that but it completely makes sense. The tightener is one the newer models of this pump.
Good to see North Face also looking after their customers. Stuff like this just makes me pick that brand in the future. Why I would never get anything but an Osprey bag.
Best of luck fixing the pressure drive, let me know how you get on, and any other cool kit suggestions. You certainly sound like you know how to pick decent products 👍
I'd say it's not the pump but the removable valve stem.
I'd agree that the removable valve stems have an influence. But if it wasn't the pumps fault, then this would happen with other pumps as well. Which I haven't had.
Use locktite in the valve threat. That would solve the problem
Good suggestion, hadn't thought of that. Although it's frustrating to have to add an extra element into the routine. But if makes it all work happy to try. Thanks NFC 👍👏
I can confirm that blue loctite solved the problem for me. Exact same pump, exact same problem with valve cores. Now I just dab some thread locker on the core after I add sealant. There is another problem with this pump. After pumping vigorously for several minutes, it can fail to recharge the cylinder on the return stroke. Instead of pulling in fresh air, it will create a vacuum and spring back to the collapsed position. This doesn't always happen. When it does, I stop and wait for the pump to cool off.
@@chrissanders4339 two votes for the loctite then - must be good!
Now you mention about the pressure thing this makes complete sense. I have noticed this but couldn't figure out what was happening. Thanks for explaining it. Do you still use this pump then?
Similar experience. I came here to figure out what I was doing wrong. I use the Topeak pump on my dirtbike with schrader valves and never had an issue. Figured my issue was because I'm new to mountain biking and presta valves. I see a commenter suggested blue loctite; I'll try that. Thanks for the video!
Hey mate, glad you found it helpful and it's definitely reassuring to know you aren't the only one. Hope the loctite works for you. Happy riding!
Sounds like your just tighten it to much on the valve end it doesn't need to be as tight as a plastic one
Yeah perhaps. I did try it looser but struggled to get a solid connection. Guess it's a fine line. Did you have a better experience with this pump?
I mean, Schrader is better anyway...I have never had any problem with them and if the inner tube has metal valve (or metal tubeless valves, which let more air through than presta), it is bombproof.
Yeah I'll be honest, as time passes I'm not sure the benefits of presta are that great for the vast majority of uses. Only perhaps road bike tyres but for a lot of riding I'm not sure what extra you get for a more complicated system. I could be converted!
@@mammothjourneys With Schrader, you can have rubber valves and those could be problematic. It is easy to cut them with the rim edge when you wiggle it around. Maybe thats why some people dont like them. But with a steel one, it is much better and the cost is almost the same.
@@ondrejmanych5688 I never really thought of that. Will check it out next time I am buying some new ones. Cheers mate 👍
I have a Lezyne floor pump and mini pump. Beautifully engineered and thoughtfully designed.
If your valve core is coming out:
1. Tighten the valve core a little more than finger tight. There is a tool built into the pump.
2. Don't over tighten the chuck on the valve. Don't tighten until it stops, a few turns is all that is necessary.
3. Use the ABS button to bleed the pressure from hose before unscrewing from the valve.
Even if you don't use a screw on chuck, presta valves can be delicate, they're soft and bend easily and therefore can break off if treated roughly.
Thanks Dan these are some good points. Being gentle with the presta valve is important for sure.
Good to hear you are having a decent experience, and with the floor pump. 👍
I’m with you, it’s a terrible pump. Here’s how I fixed it though. Remove the hose from the pump and throw both the pump and hose in the bin. Use a Silca Tattico instead. Problem solved. 👍
😂😂😂 that proper made me giggle. Good to hear I'm not alone here! Happy riding mate 💪
@@mammothjourneysno worries, glad you got a chuckle out of it. In all seriousness though, no you don't have to tighten the valve core or hold your mouth a particular way with any other pump I've ever used. Period. Its just not a thing.
I confess to having a Silca attraction. I bought a Silca track pump in the 80's and its still going strong. In recent years I've added the Hiro pump head and its easily the king of pump heads. Sure it costs as much as a small car (not really) but use it and you'll understand why. And in all those decades, I've never once lost a valve core for any reason or even had to tighten one. So they know a thing or two about inflating tires without removing the valve core.
At some point for whatever reason I decided to buy the sexy and petite lezyne pump which worked out like a crazy girlfriend - looked good, caused anguish in use. Replaced it with the Tattico which while a significant investment puts air in the tire without fuss. It easily puts air in big gravel bike tires for extra win although I've bought a Gravelero for that bike now.
Anyway the one pump and a handful of brackets means the Tattico is used on the whole fleet other than the gravel bike. The lezyne mini pump is sad and alone in the shed as a reminder of why you should never buy a terrible pump.
A further development, I'm using a Ryobi battery powered inflator with the Hiro head now instead of a floor pump. It has a digital readout and is the future I tells you. Takes seconds to top off the tires before heading out without removing the valve cores. We live in amazing times. 😃
@@KeithHeinrich There were many parts of this reply which I loved. Firstly the sarcasm of the effect of what you do with your mouth on the impact of inflation. Secondly how long you have had the initial track pump, huge love of kit that lasts time. I've not heard of Ryobi for inflation before but it makes complete sense - genius! And finally, I hadn't heard of a Hiro pump head but the engineering on it looks immense. You have taught me so much in one comment! I've not got lost down a great rabbit hole on a world I didn't know I loved - thank you!
@@mammothjourneys the Silca Pista has been around since the 1950's. It features a leather plunger washer and parts made of metal including a push on chuck, the check valve and so on. The tube is said to be columbus steel, the same as used to make bicycles at the time. As a result, there's nothing to break or wear out really.
Mine was acquired new in the 80's and was passed around before races putting air in countless tires over the years. The brass chuck made sense since stems for tubs were smooth so it slipped right on.
Around 2018 maybe I bought back my old race bike and had it restored and had the bike shop refurbish the pump at the same time since you can still buy all the spares for them.
As a surprise the bike shop had the pump finished the same as the bike. So now this fine heritage item with sentimental value still works as well as it ever did and looks great while doing it. This is why I think that there are many with a strong attachment to the Silca brand who for sure market on their heritage but take it seriously enough to build new products that are easy to use and perform.
Expensive, but tremendous value at the same time.

@@KeithHeinrich Wow that is a cool back story to it all. You can't beat quality and especially when something has that sentimental value as well. Also a lot of respect and love for a person who can build this sort of stuff, it's very inspiring. Love the link you sent through as well, some epic pics on there thanks for sharing. I presume you are over in Australia? Bet you have some epic riding down there!
just don't use replacement valves
Yeah this is something I have learnt from this pump, pick my inner tubes different!
same experience you demonstrated! with Leyzyne Road Drive an Leyzyne Pressure Over Drive
Oh no sorry mate. Don't worry, you aren't alone on this! Gutting it was on both though. What did you go for after these then?
That's THE WORST pump indeed! Whoever designed this crap should be in jail. Failed me twice...pulled out my inner core every time.
Oh no mate I am sorry to hear. You aren't alone on this one don't worry! Were you far from home?
Get the Tattico. Best of the rest.
You hero! Not heard of this one before but looking at the reviews it looks ideal. I presume you've got one. What's your experience with it?
@@mammothjourneys it's perfect. Used it a few times, I have one pump and 2 mounts. I had the same experience as you with the Lezyne.
@@rayF4rio Reassuring to know thanks mate. Will check this pump out potentially add it to the kit list!
True, Lezyne design is rubbish. Had to use Lezyne pump on MTB marathon under pouring rain, and was "pleasently" suprised when Lezyne piece of crap did unscrew the valve.
Oh no that is tragic. Couldn't have happened at a worse time. Did you know there was this risk when you bought it? What a horrendous time to find out. Sorry to hear mate - what did you go for instead?
Now it's 2024 and it is still the world's worst and in the same time most expensive bike pump! Think about you are in the mountains and it's getting dark and you have to rely on this pump to get home. It's an absolute shame!
Oh no! Welcome to the club noone wants to be part of. Have you got an idea of what alternatives you will look at instead?
Silca Tattico mini
@@randolfrothfuss8012 nice choice. No doubt you'll have a better experience, happy riding mate 👍
Tighten all of your valves properly. Problem solved. You're welcome.
Yeah I could have probably done a better job on this, next time 👍
I have the same problem with this pump. No matter how tight you tighten a valve, this stupid pump will unscrew it anyway. This pump should be called “Frustration 3000”
@@dmytromeleshko5796 Oh no I am sorry to hear. You are not alone I can assure you. What did you go for instead? Any better luck?
Try their ABS-2 chuck, if you want to experience another braindead contraption. Perhaps they should just stop "innovating".
Ha ha I genuinely thought at the start this was an actual recommendation. What's the issue with this one then??
@@mammothjourneys About the same as with the reviewed one. Sleeve not moving or very tight, grip of the chuck on the valve flaky, risk of losing the spring. On average, the whole procedure takes much longer than with a conventional chuck because of the frequent complications.
@@whukriede That sucks. I now get your comment about trying to reinvent the wheel here. Best of luck to them!
A bad workman always blames his tools. This is a well known issue which is addressed by countless cyclists over the last several decades, so look in the mirror and aware the person you seem the appropriate dimwit award of your choice.
Exactly. Which is why at 3 min 13 I call myself a moron. Happy riding mate 😁👍
I bet I could find a worse pump.
There may well be, what did you have in mind? 🤔
Simply did/does not work. Too much tech and no results. £40 for nothing... £40 wasted.
Sorry to hear mate. You aren't alone on this one. Have you found an alternative which performs better?
Skill issue.
😂😂😂 I like that. No debating that at all!
I can’t pump my tires no higher that 25psi with one of these!
That's strange. Is the hose connected right and checked the screw if you are using presta is fully released?
