We Tried To Destroy Tubeless Tires & This Is What Happened!
HTML-код
- Опубликовано: 15 сен 2024
- Tubeless tires are designed to fix punctures on the go, by filling small holes in the tyre with a liquid sealant which then sets to plug the surface wounds. But just how good are they at preventing punctures? How big would a hole have to be for the tubeless system not to work? Can we destroy tubeless tires? There’s only one way to find out…

Do you run tubeless tyres on your bike?
Yes
No because if you picture they don’t seal and you have to put a tube in anyway and just end up getting in a big mess covered in white cream
I never have before, but my new gravel bike that will be in my hands in a few weeks comes tubeless. Looking forward to it.
Yes run Conti GP 5000 & use Dynaplugs that have worked & sealed larger holes have sometimes needed a couple but they've got me to work & back (30 miles) without any problems
I would on a gravel bike but not on 28's.
One thing you missed out of the test was broken glass, everytime I've had a puncture that wasn't sealing was a shard of glass
Sometimes I've found that unlike other picture-creating objects if glass stays in the tyre it can stop it from sealing properly.
Glass fragments are definitely nasty.
i run tubeless and love them, but glass and sharp stones always cause issue, as they stay in and undo the seal created
@@garymiller1216 what else is there really that creates those types of punctures?
Isn’t that the marketed USP for tubeless?
Glass, thorns, random pieces of tire cord. That's what causes my flats, and they're always still stuck in the tire.
I've been running tubeless on my road bike for over a year now and my MTB had tubeless when I got it . I haven't had one puncture that hasn't sealed on either bike. I know of a few big thorns that I've gotten in my MTB that I had to pull out that sealed instantly. I know I've had a few punctures on my road road bike as I've seen small little holes with sealant that has leaked put. I did not even know I had punctured. I ride in South Africa and the roads are terrible in my area and they are littered with broken glass. I will never ever go back to tubes. After having about 10 punctures in 2 months on my road bike, i was ready to give up! with tubeless, going over a year without having one has been amazing!
Really impressed, might switch to tubeless after that, so glad about the small amount of "hissage" :) :) we love you Ollie
More effective than the jibbyjab, that's for sure.
I would like to see the inside of the tires after all those punctures. When removing tires, the sealed holes are very apparent - and satisfying! And in my experience, the clotted sealant holds strong.
I just cleaned out my tyres at the weekend. Removed all the dry sealant, including the clots and they didn’t leak at all on reinflation. Very pleasing.
Good test. Very impressed! I’ve been using tubeless tyres for three years. I’ve not had a puncture or I haven’t noticed because the sealant has been so effective.😊
This was not a test, it was an infomercial/advert for Muc Off. From the numerous fanboy comments of happy surprise and personal support it was an effective production.
@@johnb.8615 Pretty bad advert for them considering Muc off was only mentioned once to let us know the type of sealant used and isn't even linked to or mentioned in the video description.
@@sugonmaballs The minimal specific product reference and absence of obvious brand promotion--the nonadvertisement format--allowed more flexibility in content and contributed to face validity. You don't really believe a 28mm tire can have that many punctures and still hold 70PSI, do you?
What brand of tyres and sealant do you use?
@@sandythemonk I have used Mavic tyres and wheels and Mavic sealant and the Stans sealant.
How does Ollie manage to combine 90s film references into cycling so seamlessly?? Bravo
He practices while he's out riding his bike, obviously.
Alien, Bullet, Terminator and Swordfish were the ones I heard when I was paying attention. Probably others that I missed.
The scene in alien... hahaha
I have been running tubeless for over 2 years now and love them. Especially when folks tell me I’m getting a flat. I think you should keep running those tyres and let us know how long the last and keep pressure
Second this recommendation.
Yes. After 30-ish years of road riding, I recently switched to tubeless. Very happy so far. I've been running tubeless on my mtn bikes for 10+ years and haven't had a flat in all that time.
Thanks for sharing! Whatever works for you is always the best option.
Definitely agree with everyone else. Would love to see glass or thorns. Those are the most common types of puncture debris that I run into.
I’ve had a thorn in my tubeless, pulled it out and it sealed back up no problem. Was quite a big one as well
I like it, I wish it had broken glass as a test, either a freshly broken bottle with larger/sharper pieces, then some more of the smaller/swept aside pieces that are older.
I’m riding 12,000 miles per year and just don’t get many flats. When the tubeless fails, you’ll need tubes or patches and you’ll ride home with a low spot unless you can reseat the tire. You’ll never get the rush of air to refill it on the road. And good luck getting the tire off. I got rid of all my tubeless wheels. Also only riding rim brakes. Discs are a pain in the neck.
Being on a club group ride when the person in front who has tubeless gets a puncture & I'm covered in latex spray is something I've had a few times & I hate it 😡
Yes I’ve seen it happen a few times. It’s always a small cut.
Especially when you're wearing your brand new expensive kit and you can't get the gunk out of it!
A lot less annoying than all standing around, whilst they change a tube!
@@piandbash442 No far more annoying Happy to wait for someone to change a tube Not happy to be covered in gunk !
Just converted to tubeless P zeros 28mm. Not only are the great a sealing punchers but they have made my Focus Izalco max faster and more comfortable. Now my MTB, gravel and road bike are all tubeless.
Wow that's crazy! I can't believe they sealed all of those punctures. I got some wheels that are tubeless compatible but am still running tubes. Might have to give this a try
Same.
A couple weeks ago on a gravel ride I picked out nearly 30 goatheads from both tires and each had sealant squirt out a tiny bit. Only had to add air to the front a bit but so thankful for tubeless tech. That would’ve been a rough and long walk home through the desert if I still used tubes lol.
And so far so good with 30c tubeless road rides with the crappy roads in these here parts.
what a great video, absolutely worth getting tubeless for sure, especially after this video, plus the one you guys made of setting up tubeless, keep the superb work going guys
I'm impressed by the test. It would be interesting to see the outcome riding over glass. My bike shop guy wants me to go tubless and use the foam as well.
the foams are useless. they don't do anything but make a mess. but tubeless and 50psi or something in road tires work splendid.
My first foray into tubeless didn't go well earlier this year when I managed to puncture (sealant everywhere!) on a pothole at speed.
However I'm glad I persevered as I've remained puncture free despite it being hedge cutting season here in Derbyshire!
Ah sounds like you got unlucky, glad to hear the puncture gods have been on your side. 🙏
Great video! I had kind of a sidewall gash a few days ago which took 2 plugs side by side to sort out but after that I was able to finish my ride (which was around 50 miles after plugging) with no issues! The tire is still holding full pressure and I didn’t have to remove wheels and deal with inner tubes in a busy area. Tubeless forever for me!!
Fantastic! Tubeless really can get you out of a sticky situation.
I went tubeless (and hookless) two weeks ago. In the week before that I had a run of 5 punctures in 4 rides! Loving the lower pressure in the tubeless setup and I’m smashing lots of my personal bests on Strava. I’ve bought a small hand pump and a dynaplug thingie and that’s all I carry on a ride now.
I’ve seen a lot of these tests where the sealant works magically but I had many punctures with holes too tiny for a tire plug which still didn’t seal. And when they eventually seal at a very low pressure it rips right open again when you pump the tire back up. Am using Stan’s Race by the way.
Try the Mariposa sealant additive to add a some granularity to the sealant.
i didn't find that stans worked very well on road tyres....better on wider gravel/mountain bike tyres. Continental sealant worked well but I run with Peatys now on road and i've found it works very well. With plugs......they can take some force to push through the tyre but they do work very well, again I use Dynaplug as I found the "bacon strips" just got messy and dynaplug is s neat package.
I use stan’s race too, but it needs masses of shaking (at least 5 minutes) before putting it in the tyre otherwise the granules remain at the bottom of the bottle and don’t mix properly with the sealant.
Have had several of those punctures as well. I’ve only used Stans DART plugs and the trick I’ve found was to just peel off a “leaf” from one of the darts and use the tool to work the leaf into the hole where the full plug wouldn’t get through. It’s frustrating at times but the DART seems the best tool for those punctures rather than “bacon” strips or dynaplugs. Using normal stans in 30c tires and that method has worked 95% of the time and being able to get back up to 50psi
@@JohnnySantoDomingo Haha, I did the exact same thing!
This is very timely for me, I just came back from a metric century during which my tubeless tire completely failed. These tires were somewhat old (a bit over 3000 miles on them) and the last time I inspected them I noticed they were getting soft and thin in a few places but I put them on, added sealant, and was ready to go. I definitely noticed sealant coming out of a bunch of places but it sealed and all was good. About halfway into my ride, it felt as if a spray hose had turned on under my legs, hissing and spraying orange sealant was everywhere. It turns out there was about a 1.5 inch by 1 inch portion of the tire that was popping up like a balloon! As the sealant blocked the small puncture in the middle of that section, the balloon "inflated" and the hole became larger, spraying sealant and losing air. If I tried to put my finger on the hole, the soft portion kept growing to the point it seemed as if it would literally pop like a toy balloon. No repairing that for sure. However, I did finish the ride simply by adding a tube in the tire; I kept the pressure a bit lower to ensure the tube itself would not push through the soft portion of the tire and tried very hard to avoid any gravel or other "danger" zone.
The moral of the story is that indeed, as Ollie mentioned several times, you just don't even realize just how many times tubeless tires save you, and in my case, I just became compliant and kept riding with 3000+ mile tires even though after cleaning and refilling them with sealant they were oozing sealant from a bunch of places. I guess that should have been a sign!
Thoughts and prayers go out to the families and victims of the GCN Stinger Construction Tragedy... We will never forget your sacrifice 🙏
Cool video GCN, for some reason, i like my tubes still.. but nice to know these results.
I have run tubeless for seasons now and had 3 flats which were unfixable. All three were torn open side walls. 2 with Conti GP5000 S TR and 1 with Schwalbe Pro Ones. The best sealant doesn't help if the sidewalls just burst open. Will go back to inner tubes now.
A sidewall tear is pretty catastrophic with tubes as well.
@@andrewmcalister3462 True! However, I can just change the inner tube without much hassle, perhaps with a bar wrapper in between inner tube and tire to prevent the tubes from bulging through the tear. I could do the same with a tubeless setup, but it's a huge mess with the sealant. At this point I don't see the advantages of tubeless anymore if I still have to carry around spare inner tubes. The weight and rolling resistance thing is negligible for a recreational rider.
@@ProfGoodlife True that on the mess. I accept that risk for the benefit of fewer punctures overall, but others may make different trade-offs depending on their local conditions.
Conti sidewalls are rubbish. Tubed or TLR. Try Vittoria.
I've been running tubeless tires for a while now (4-5 yrs with a total three pairs of tires). Although I did enjoy all this time with tubeless tires there is one big caveat which is seating the tires onto the wheels. Honestly, it's a mess and most times you won't manage to get the tire properly in place. Even in bike shops I've seen mechanics struggling to seat the tires. Other than that and occasionally spraying sealant to your friends it is great indeed. While riding on highways in São Paulo I once got home with three or four tiny pieces of metal that would have punctured my tires if it wasn't for the tubeless set up. So my take is, if you ride where punctures are very common I'd recommend going tubeless, if that is not the case in your area sticking to inner tubes might be easier and cheaper.
I have been running tubeless on my mtb and my gravel bike for quite some time now and it's almost a setup and forget type of thing. On MTB's it used to be that every time we would go on a ride someone would get a puncture (snake bite, usually). Thankfully those days are gone!
Ok I'm sold now. After watching countless videos. I'm all in 👍🏽👍🏽
Road Tubeless here (Pirelli P Zero TLR 30mm), no issues with the tire plug I had to use. I run at 4 / 4.5 bar.
An interesting watch! I'm resisting going over to tubeless, for the very simple reason that sooner or later there will be a puncture which won't fix itself. I don't want to be stranded by the roadside trying to get a tight-fitting tyre off the rim. I like my bikes to be easily fixable by the roadside, and in the end it's no trouble to carry a couple of spare tubes and a puncture kit everywhere.
You can always carry tubes if you ride with tubeless tyres. The tyres are easy enough to get off the rims to fit tubes if deflated, they just push off with your thumb. I carry two tubes on my tubeless gravel bike, not needed them though, found two holes in the rear tyre that I didn't know I had, deflated to top up and noticed them as the seal broke when the pressure released. Topped up, pumped the.back up, sealed again.
@@jackothekingUK I bet trying to fit a tube in a flat tyre full of sealant makes a hell of a mess, though! I can't see the point of going tubeless if you still have to carry spare tubes just in case. Admittedly, Ollie's demonstration in the video shows how effective the tubeless system is, but I still can't see enough advantages to outweigh what I perceive as the disadvantages. Mind you, most of my riding is solo and not really time critical, so there is that.
@@ragwort3369 I used to think the same thing, still got to carry tubes and a pump, what's the point? I had a hole on my front tyre just today, it hissed, spat out some sealant (bit messy), stopped hissing, finished the rest of my ride (12 miles), put some air back in when I got back, left it. Ready to ride tomorrow... I can imagine it's messy putting a tube in a tyre that's had sealant in it, but preferable to walking home if the tyre picks up a gash. Ultimately you try it or you don't, it's your choice.
I have done over 20,000 miles on tubeless. Only had to stop to put in a worm 4 times in all those miles and always got home. Putting a worm in the tyre is much easier than changing a tube (especially when you have cold hands in the winter), and you don't need to take it off the rim. Other than those 4 times, I haven't had to stop once for a puncture in all that time.
It's a no-brainer
@@piandbash442 It might be a no brainer if you already have tubeless wheels. Having to shell out for new wheels just in order to go tubeless makes it a slightly different story!
After a few years of resisting the cost and faff of tubeless tires, I'm a complete convert. Yes, they tend to be harder to mount/dismount. Yes, they can be hard to get to seat. But as Ollie's experiment shows, they can almost eliminate those common, small puncture flats.
Also, though maybe just my imagination, they give a certain suppleness and compliance to the tires that improves ride quality.
Yes and the bigger tire size you go the easiest is it to mount. That's why it's hard for road tires and flawless with gravel and MTB.
I run tubeless for my gravel bike (40 mm tires) and still have tubes in for my road bike (28 mm tires). I am tempted to switch my road bike to tubeless. I have only had one tubeless problem so far, when my sealant wasn't good enough to seal a hole because it was about 6 months old. I now try to replace the sealant every 4 months. Your comment about darts not working very well for road bikes was very interesting!
Have a "quick" fix for the glass shard issue (the very big ones never seal and plugs might won't work due to the size of the cut). Commuting in Lndn for many years, conti GP5k TL and TR in the last 3 years.
Move the puncture to the top, no need to remove wheel if not in the mood... Remove shard. Deflate tyre if there is any air left. Grab your tyre leavers and open up that bit, as much as you need to access hole from the inside. Wipe it down thoroughly. Apply a park tool GP-2 "glueless" patch from the inside after a bit of sanding. Pop back tyre, inflate, and good to go. If you don't carry a CO2 inflator or a track pump, it's a good idea to do this near a bike workshop where you can use their track pump. I had to do this maneuver 3 times so far, and those patches hold.
You can use classic cemented patches as well, but it takes a lot more time and they are more rigid so you really want to wait for them to properly bind, otherwise they detach in some parts and you lose pressure again.
MucOff glueless patches unfortunately don't work at all in tubeless in my experience, they detach instantly, but you can use the lovely box to keep the Park Tool ones...
i have had no problems with tubeless road tyres except for a few sidewall punctures which I have had success with plugs that have an end to stop them being blown out by tyre pressure
Tubeless is nice for people that have regular flats. For riding on the road here in the Netherlands they are just overkill. I have a flat maybe once a year and probably less.
Dreading going to work on Monday now… all the cycle lanes are going to be covered with DIY stingers…. Thanks Ollie & GCN!!!
When it comes to plugging road tyres I found that the thicker, usually black "worms" (or using 2 thin ones at the same time) stay in place and seal better than the thinner brown ones, and the thinner ones work fine for off road pressures where the thick ones are overkill. Kind of goes against what you would expect but if you think about it it makes sense, its all about the pressure.
I've had great results with tire plugs, even on a size 28-32mm tubeless tire (as well as Tufos tubulars)... love all this sealant and low pressure tech.
Some of the screws seem to have failed to penetrate the tire because they got either moved to the side or the tire went over it. They are slightly less sharp hence the zone 2 was more efficient at making the holes. Still it's also true for the real world scenario hence the test is perfectly legit. Thanks! I wonder how would be the results with a bit worn out tire.
Ollie gets excite the Yorkshire really comes through!
Tubes: 5 mins to change a tube once or twice a year. Tubeless: giant mess, need to "top-off" sealant. Need to very carefully clean the rim before mounting a new tire or it won't seal, and finally, sealant spraying all over my bike. Gravel, mtn, sure. Road, no, not worth the hassle.
I am very impressed.
If I rode where frequent puncturing is a problem, I would strongly consider a tubeless set-up, but I do not need to.
Yes, I'm a convert; after being a luddite for a fair while. Pirelli tubeless are very good, tho my 90kgs wear out Cinturatos less quickly than P Zeros.
Even thought this is the second of these videos you have done I still enjoyed it. I have done over 13,000 miles on tubeless road tyres and only had 2 known punctures that did re seal, the worst was a packing staple in the rear tyre, me and my buddies got covered in sealant, after a few spins of the rear wheel it sealed and I was on my travels again.
Great to hear! 🙌
Old lady ‘Gerry - quick, take the Mini and get help there is a strange man dressed like a power ranger holding
wood filled with nails’ 😢😂
I'd be curious to see how things go if you kept riding right after the punctures. Would the sealant still manage to dry up and seal the tyres under the pressure of a rider's weight?
It works
The highlight was the lady in the background shushing the person leaving in the mini 😂
The suburban bungalow estate background with the old lady seeing someone off in their mini, halfway through the video, really added to the sense of danger here 😅
What a great review, answers so many questions
Tubeless works really well for me and adds a level of comfort you can't get with tubes. Normally you never even notice you've had a puncture until you get home. Only ever had one puncture that I've actually noticed and that just slowly let air out over the ride although I didn't need to add any air. Only reason I noticed was the wheel jizz all over the bike and you could see it squirtting out when out of the saddle. I tyre patched that one after a few more rides. The ONLY downside of tubeless is setup because it can be really frustrating if you have a rubbish low volume pump. I have a tank and it's now so easy. Originally had pro ones and now on GP5000 TR(?) Which mounted up really easily unlike tubed GP's where you normally need thumbs of steel.
Done 900 km, including 2 century rides, on my road bike since I switched to Vittoria Corsa NXT with inserts. No flats in the whole time. I was getting flats every three rides or so with my Goodyears with tubes. Once in a while I can see a little white juice coming out of a pinhole, but other than that, no issues.
These tires have greatly increased my enjoyment of endurance riding.
Rode across the US in 2016 on a CX bike. Mechanic friend persuaded me to run tubeless and built up the wheels using Stans i23 MTB rims… 5200km later: I wore the rear tyre out and only had one puncture on the rear that wouldn’t seal (turns out it was a cracked rim) popped a tube in and finished the trip. Front wheel had no puncture and no drama. Have run tubeless ever since
I have a feeling that the tire's puncture protection dealt with zone 1. Cool to see the sealant doing its job beyond that.
Let's see the part where you cycle home on them afterwards, to see how well the seals last. In particular get it up to 36km/h for 40mins > I bet the holes come unsealed again.
Also show how you can continue to run the punctured tires longer term rather than just chucking them in the bin (adding to the landfill.) E.G. taking them off and patching them internally with regular inner tube patches.
radial patches a better choice
I ride sealed puncture tires until the tread wear indicators tell me it's time to change the tire. I don't even know they were punctured until the worn out tire is off the rim and the cured latex "plugs" become visible.
Good to see Brian May is looking well at 5:33
Dear GCN,
whatever you do in the future, please get Ollie to do more Schwarzenegger impressions.
Lots of love
So the puncture seals, but will it still seal a week later? I often find that TL seals but the seal keeps braking when I inflate back to higher pressure or after some more riding. Also, fitting tolerances differ, so not all TL tires will work with your rim. Some will just slowly leak air and you’ll end up pumping your tire twice per day. I’m strongly considering going back to tubes as a result.
Great video! I go tubeless on all my bikes now, well except my BMX bikes. In the last 5 years I have gotten a flat once and that was on one of my mountain bikes going downhill and I hit a sharp enough rock to make a hole too big to even plug.
I used to get 2 - 3 or more flats a year when I ran tubes.
Thanks for sharing! Tubeless for the win 💯
Loved the "Tire of Death Board" Ollie. Three things to add next time, broken glass, puncture vine - goatheads and sharp tree branches!!
Been riding tubeless for over a year now without issues. Until a few days ago when I crashed in a roundabout, as it turned out caused by an almost flat front tyre... It did seal itself back home when I refilled some sealant.
Hard lesson learned: keep topping up that sealant regularly, running dry works only as long as you don't puncture!
Thanks Ollie and crew . I use tubeless on my off road bikes , I've tried inserts as well . The stuff works , I use a different brand tho !
Great show Dr Ollie. Added to your ‘ying tong tiddle eye po’ (See The Goon Show) Chinese group set: how about Chinese wheels and tyres ridden over the precision built GCN fuzz-stinger-tyre destroyer thingy? Or, GCN v GMBN v GTN v EMBN over the GCN stinger thingy thing?
I gave the video a “like” purely for the Terminator 2 reference. The rest of the video was just a bonus for me
I've been running tubeless for almost two years on my road bike and have had success with the exception of 1) a small brad nail that punctured the tread and then went on the skewer the sidewall so no help there and 2) caught a horseshoe nail that went in halfway and stayed there while the sealant was spraying all over me and the frame. Overall, they are a keeper!
Great test, I'm using the same tire run tubeless I have experienced a cut and sealant can't fully seal it. I use a tire insert to patch it(similar with car tire repair) and still continue to use it till now without issue.
When you say tire plugs don't work, you should try the Dynaplugs. I've had bad experiences with bacon strips but the Dynaplug work really well on road bike tires (and gravel tires as well)
I run tubeless tires on two of my four bikes (carbon road bike and e-gravel bike) and have ridden both bikes a total of 16,000km with just two flats. Both times, after taking the tire off, I realized that I had waited too long before adding more sealant, because the inside of the tires were 95% dry.
Lesson learned for me-don't wait too long before topping up my tubeless tire with more sealant.
Been riding tubeless for about 4 years now. Last season was the first time I tried Muc-off. Worst season I have had in terms of punctures. Back to Stans for me
Best part of this video is the cameo by your grandma at 5:37
5:35 “George…..George ……. those bloody cyclists are filming again, quick get the tacks out”.
😏😂😂
Congratulations. Your tire sponsor will give you new tires now. Clever👏
all good, but please include in your test some other obstacles that are not so pinchy... i can recommend broken glass bottle pieces, specially with curve near the bottom - in such conditions I've destroyed two tubeless tyres already :(
The only two flats I’ve gotten t the past five years or so were catastrophic slashes. I use puncture-resistant tires and have run over plenty of debris on the road. Seattle roads are also notoriously pot-holed and never had a problem. Still seems like tubeless requires a lot more maintenance that tubes don’t need. Maybe my tires - slicks - are a bit heavier, but I’m also not racing. Still rarely get passed, though. Why deal with the maintenance hassle?
Really good test, really useful. Thank you!
Glad we could help 😀
Hearing that head unit, it sounds like he was tracking even the rides over the board 😂 what a man!
how old is the sealant? will it work after 4 or 5 month or in the winter?
been riding tubeless on my mtbs for around 7 years. Had to use a plug a couple of times, but never had a ‘proper’ puncture in that time.
What sealant did you use?
I have the same tires. Love them. Same sealant too.
I prefer using sealant in a tube, when it does fail you can stick a new tube in by the road instead of being screwed.
I love the way Ollie gets more "Biker Grove" when he's talking to himself.
The tests are definitely impressive, but I've had the opposite experience with Pirelli P Zero Race 700x26 tubeless tires and Stans sealant, riding a mix of smooth roads, some chip seal, and an occasional pothole. Had several gashes that would not seal, likely from shards of glass or potholes. Just goes to show that tubeless will not magically make a race tire indestructable.
I run tubeless front and tubed rear - the only flat i had in three years was the tubeless. After WWIII trying to remove the tire i finally manage to stick a tube into the sticky mess and kept riding.
Yes, tubeless bike tires are effective, they are really good indeed. But sooner or later when the ciclyst rides in group or in lonesome, it will arise the need to carro at least two inner tubes and a set of good quality tube patches.
Love his sarcasm
Tyre pressure matters for sure. I had muc off in a set of p-zero tyres, but at 110psi (I'm chunky), and the pressure just pushed all the sealant out. After I dropped down to 80psi, I'd say it performed better.
110 PSI is well above the max recommended pressure for the P-Zero tyres even for a heavy rider. Stick with your 80 PSI, much better all round (so to speak).
Just set up my grail with tubeless, front wheel no probs, back wheel three days of faffing to finally get it to play ball. It’ll be interesting to see how it handles glass shards which seem to be the Bain of my life on my commute.
What sold me was the time I rode to the top of our hill to take a photo, looked down and I was in the midst of a big prickly pear cacti patch.
BEST GCN PRESENTER …. Ever .. someone massage those family jewels
Love tubeless, even the old getto versions when they worked!!..
Ps. You should of ridden the pothole in the other direction!....
"Bye Barbara, see you next week for that coffee" 🤣
70 that's still very high for that meny punctures. I still prefer road cc´s test thy did. The Silka sealent seald a hole from a 7mm screwdriver. that was impressive
Would be interesting to see tubeless against other stuff. A broken bottle was enough to get me an unsealable flat on the way to the start line on the Tour of Germany sportive. Obviously Murphy is only interested in getting you if there is something at stake.
I had the same when my riding buddy had a puncture on the way to a local sportive and I was shouting at him to keep turning the pedals to get it to seal. Once at the start line we got the mechanics to top up the pressure and we managed to complete our ride
That is genuinely impressive, I run tubeless but never have thought they seal THAT well !
It depends on the combination of the tire and sealant brand but most will do the job for small punctures.
I want to know what happens when Granny comes back in the Mini: will her tyres survive the GCN Mega Stinger of Doom - that Ollie helpfully left in the alley - also?!
impressive. might convince me to switch from inner tubes at some point. i just wonder, since this test was run in dry weather, how the sealant would have performed in rainy conditions?
When I was a school back in the early 80's some toerag was putting drawing pins in any bike in the bike racks. I was cycling home and could hear a regular clicking, so as I stopped and took the drawing pin out I immediately had loss of air, never found out who it was.
i am running tubeless on my bike for 3 years now and I have no idea if I ever punctured. I am quite aware of the road so I try to avoid glass/nails and other sharp shit that I can see. Overall I love it especially with the extra comfort from the lower pressure
I don't think there is any denying that sealant works great on uniform round punctures. But any gash or slit seems to be a real struggle for it. Especially at typical road pressures.
Great point. The only flats I've had in the last three years were always gashes - it took a tube to continue.
