I'm a mountain biker but I keep watching GCN because of how well Jeremy presents and explains what he needs to say. I've wanted a gravel bike because of Jeremy!
The easiest way to measure existing clearance is to use allen wrenches and see what you can fit between tire and bike structure or brake parts. This is way easier than trying to measure the openings as the surfaces are rounded and tapered. So mount up your existing wheels and tires and then measure your clearances (write them down!). This should be the first step. Then you can begin to figure out how much bigger you can go. For instance, on my 09 Madone with stock rims and 25c tires, I have 5mm minimum clearance to anything in the back but only 3mm in the front. So a 28c would be sketchy to run in the front. In my case I had to swap out the fork, stock would be a few mm wider and I could then run 28c.
As a recent buyer of a Gravel bike, we need more of Jeremy. It's hard not to get carried away with his presenting style and he's an inclusive as it gets. Bravo JPows !!
I use tubulars on the high profile carbon rims of my racebike to my satisfaction but switched to tubeless tires for my trainingbike some years ago. With the 2 way fit system of Campa Zonda and Fulcrum racing 3 it took me some time and patience. The 25 mm Schwalbe One TLE tires on the Fulcrum racing 4 wheels of my Orbea Orca Aero work very well though! Mounted them without tirelever, got them seated with my trackpump ( after spraying some soapy solution between rim and tire ) and have ridden them for 3 weeks without any sealant inside( at 5 - 6 bar )! The slow loss of pressure seemed to worsen every week so I put a little sealant in the tires and take a little bottle of latex with me on long rides. I had one puncture which sealed put eventually I repaired the tire from the inside. The Schwalbe One tires of 2020 are a lot more supple than the Pro Ones of 2019! Curious how the latest Pro Ones will perform. Thanks for the interesting and entertaining video JP!
Woah! Your comment has all my fav wheels on it: Campy Zonda / Fulcrum Racing 4 (Quattro) mated to Schwalbe One tires. Is the new Racing 4 two way fit as well? If so...How snug does the Schwalbe Pro TLE fit on the rims?
I love seeing someone else using an Empire Caliper! Those things are made in USA and only about 20-25 bucks, super convenient things for bicycle parts or woodworking. Model number is 2787 for anyone wondering. PS: Really old rims are also hookless. They only work safely up to about 60 PSI when using 32mm clincher tires.
Started cycling a month ago and already need a new tyre and tube after running over some glass and slicing the tyre pretty badly. Cycle routes are pretty bad (picking up a fresh puncture every week) so started Investigating Airless solid tyres and Armour inserts and my mind is now pickled. While this video is excellent explaining the complexities it has given me so many things I haven't thought about. Looking at manufacturers spec sheets I can't even find half the information needed to piece this all together. Probably be next spring before I work all this information out!
I very much (super) enjoyed this excellent (super) and informative (super) video as I never quite (super) understood how (super) difficult it can be to choose the right wheel and tire combination. If only the choice of adjectives available to us was as wide.
Thanks Jeremy, good one. One catch with hookless rims is for heavier riders... With max pressure at about 80 PSI on most rim/wheel systems a rider who is say over 85 or 90 kg can run into issues where the pressure is just too low for proper bike handling at say a 25-28mm tire width. Best to stick to hooks if you're a heavier rider IMHO.
This is a conveniently omitted detail on many manufacturer's websites. They'll list max pressure by width, but that crucial bit--max load at a given pressure, isn't there. It can be an issue for anyone that carries cargo on the road.
@@seitenryu6844 Yes. I think so... Especially when even relatively little additional loads like full bidons, tools, or light bike packing bags can add a significant % to the total system weight. Another example of tech for the pros not necessarily being tech for the people!
Having tried to load a couple of tubeless tyres on Mavic krysium elite disc and DT Swiss PR1400 over the last 18 months or so, I am waving goodbye to tubeless, it’s just to much hassle setting up. As I do a lot of solo rides I feel if had a catastrophic Problem out on the road,it would be a nightmare to deal with, so dealing with inner tubes and mounting normal clinchers isn’t such a big deal to me. And to be honest the Conti 4000s 28c I’ve just put back on my DT Swiss wheels rolls so smooth, I’m happy and confident. Manufacturers need to get there heads together and decide on one size for all.
how old are your Mavic Ksyrium elite ? i have 2012 ksyrium elite (rim brake) and i have difficulties to fit new GP5000 25mm instead of GP4000s 23mm. I was ashame when i have to go to my bike shop to ask them "please, save me, install my tires"... and now i have a puncture... i can't even remove the tire from the rim ! am i too weak ?
I've got Cero AR30 Rims with Continental GP5000 Tubeless set up. I tried to fit the tyres without using levers and I ended with sore thumbs and a terrible afternoon haha. Ditched the advice and used tyre levers. The Continentals were still a pain to get onto the rim but got there in the end. Total time to fit the tyres an entire day !!
After 5 years of running tubeless road tyres with sealant I have just given up and am going back to tubes. It's just too much hassle and mess should you encounter a problem. I've tried all the sealants and found the only one that really works is the Orange Seal sealant. Also, I discovered that the sealant gets into the inners of the wheels, as no wheel is completely sealed and it dries out inside the wheel which you can't get to to clean it out! Not something I want on an expensive pair of road wheels.
Same here, pissed about with tubeless when the hype started up. It's just not worth the hassle and nonsense. Tubes are so much easier, and nothing beats the comfort of latex tubes too, tubeless doesn't even come close. Don't even get me started on cleaning out old sealant ...🤢
Yep. Gravel & Cross wheels set up tubeless has been a good idea, due to the larger air volume, but for the road -- latex inner tubes with standard clinchers all the way. I'd way rather slam a new tube in on a group ride than figure out why my tires isn't sealing... While the group stands there shaking their heads!
You should check out wheels that don't have spoke holes, like Yoeleo & Fulcrum Racing Zero. That said, I'm with you on not going tubeless on the road, not worth it for me.
If like me you don't have a compressor or travel with your bike set up tubeless I can strongly recommend the milkIt booster kit. It's the size of a bidon and you can charge it with a bike pump. Easy to mount new tires or reseat ones that have come unseated for any reason. To add to cogged combo of rim/tire I have found that both Schwalbe Pro One and Vittoria Corsa tires seat easily on HED Belgium rims.
I "HAD" a pair of mavic all road elites rrim brake and they were great if you get tires on them! i managed to mount a pair of tires and tubes on them once! let me add that i am a former pro football player at 275 lbs and very strong hands. (trying to be modest, also!!) there was no way in hades that i could mount tubeless tires on these rims no matter what i tried wether it was soapy water, making sure the bead was in the deepest part of the rim or heating them up in the oven!!! so, i no longer own them much to my chagrin, although i no longer have nightmares about hearing a distinct hissing sound out in the middle of nowhere and facing trying to change a flat without the aid of an industrial tire changer!!!
So to optimize performance, what size tire should we use on a rim with a 20 mm internal width? My wheel manufacturer says that The ideal size tire is a 700 x 23 through 38.Or, what rim with should be used with a 700 x 26 tire and a 700 x 28 tire?
Great video cleared some confusion for me! I’ve Giant SLR1 rims which are tubeless ready, and are hooked. I thought you had to use tubeless tyres , which I’ve been doing. Good to know you can also run standard clinchers with a tube too! BTW for info Schwalbe Pro One goes on easy but are difficult to seat. Conti GT 5000 are a bitch to get on but seat really easily!
Clearance on my road bikes is limited by RAM, radius, not WAM, width So this new terminology is helpful, because previously most people just talked about width, which was not the real problem, at least for me
Jeremy, I'm confuzzled. At 2:55 you say you can only run tubeless on hooked rims. Then at 3.04 or thereabouts, you say can run tubeless on hookless rims. You really should correct that with an edit.

Cool vid, but totally confused about rim width. How much variation is there in wheel rims across the industry? What are the standard or "popular" rim widths? And what happens if trying to fit a 23mm tire onto a 22mm rim? Thanks for the content. Love the energy.
Rim widths vary widely, you can use charts to check but they also don't usually agree across the board. Unfortunately there's no clear answers besides "try it or ask your LBS what their experience is".
My rim seems a bit to the bigger size I find it extremely hard to put tire on Doesn't matter if it is stock outer tire that came with my bike or my new Vittoria tire have a high chance of breaking my tire lever caz its too hard to fit I bought a set of 3 levers and now left with 1 Rim: Merida Scultura 5000 2017 Stock Rim
#askgcntech 28mm tyres/17mm inner rim width is what I am used to. Why GCN doesn't make tyres' reviews? GCN in espanol has an episode trying several Vittoria tyres at Vittoria's headquarters test track. Not a proper review but it's something, but at GCN I haven't seen that. I use clinchers and had to resort to Bikeradar and the likes to find the best tyres of 2023 and things like that.
Nothing mounts properly to my WTB rims - personally I would avoid them. (Bike came with WTB tyres and they are also a pain.) To get a clincher to fit i have to pressurise up to about 50% over the max pressure. For tubeless the pressure canister works and helps, but if I get a puncture at the roadside I have no chance.
So, I have an orbea orca that the bike shop installed 28s and the rear barely rubs. another bike shop told me that it should be okay and that there is no problem. Youve mentioned something about frame failure, this is a carbon frame, I'm I looking at frame failure if I only ride road and no gravel? Thanks!
Tried to put continentals on mavic rims and after breaking 4 tire tools I had to cut the tire off the rim. Frustrating and expensive. Oh, and that little exercise took me about 2 hours.
So much good info. What about manufacturers of tires that aren't true to size? As an example: I've noticed that Bontrager measures true whereas Continental measures larger (23c is closer to a 24.5c) where they're compared on the same rim. It's caused me many issues with my Noah (2011) with emergency replacements at shops and my wider rim wheelsets when really putting power down. And also as the frame ages.
Dumb question, my 29er hybrid has 37-622 tyres and I want to replace them with some quality ones, (whole bike cost me €120 brand new) the internal rim width is 21mm so how narrow could I go? I'm guessing a 28c or 32c should be no problem but just want to know before I buy online....cheers
Can @GCN or someone PLEASE clarify something in the video? @2:50 Jeremy says "you can only, only, run tubeless on hooked rims", which is then contradicted by the slide after that says you can run tubeless on hookless rims. I understand not putting clincher tires on hookless. Jeremy is the best presenter on GCN!
I'm not an expert, but I think he misspoke in the first part of these remarks and meant that hookless rims are only appropriate for use with tubeless tyres.
@yo dugldo Two blowouts, and too many punctures which don't seal. I've gone through 7 tyres this year. Gravel Kings were useless, pirelli useless, so gonna try something else.
@@bensaund Not good! I've ridden thousands of miles of gravel on tubeless GravKingSKs without failures. Why not see what the winning riders of Unbound used and go with their success?
I would love to see the bloopers at the end of the video - 3 tyres tried, broken plastic tyre levers, sealant over the floor, repeated (unsuccessful) inflations
Hey J , your using your calliper wrong or should I dare say Vernier ! Those edges you used are for outer diameter and the little ones on the other side are for interior diameter. The way you used it I would say you lost about an inch !
I'm looking for a rim that best suits my 38c gravel tires, what's the widest/best rim I can put the tires in? because I heard that using wider rims for your tires can lessen the contact point of your tires to the road. I'm looking for that flushed aesthetic as well
I Dont know i had a 19 mm rim with a 23 c tires and looked like a bulb but then i got 23mm rims and looks good but i dont notice a differen but that 19 mm rim i put a 35mm tyre and is too much the tyre is too soft needs more support (a wider rim) i think think the best is to use the same size of rim and tyre. But for road depending of the pavement a 23 is not enugh i like 28 in the rear snd 23 up front
presenter challenge: mount new tiers on a rim. new as in take it out of the box and fold it out.. and THEN mount it. it needs to be aligned with he valve as well. tubes or tube less is up to you
The internal rim width to tyre width stuff confuses me a little. I always see people talking about fitting tyres on a wheel that'd a narrower internal. Rim width. Is it possible to do the opposite? For example, I have a hybrid with a 30mm width rim, could I fit a 25 or 23mm tyre on it? If its possible but just not ideal, what would be the problem with doing it?
@@gcntech I feared that was the case. It's super annoying, I wanna put the bike on an indoor trainer but there doesn't seem to be anyone that produces 30mm trainer tyre, everything is either 23 or a mtb tyre
Continental GP5000 TL doesn’t go on a Mavic Cosmic Pro Carbon UST rim.................gone back to Mavic Yuksion UST pro but looking for other suggestions
The bike is solid and my Ebike conversion went great. ruclips.net/user/postUgkxHL1v1R3NE5x4KiYfyt8dnQmyNYz7qi5L Very smooth ride at 30mph with no problems (135 miles ridden so far). The picture is a bit deceiving - there is WAY less space in the center of the frame than it shows. The suspension connection takes up the entire thing. So I needed to attach my battery on the bottom of the frame and my controller on the top. Instructions for assembly were lacking but honestly it wasn't too hard to figure out even though I have very little bike knowledge. Watched some youtube videos on adjusting the disk brakes but that was it. Still, I am loving it and very happy with the purchase.
I was wondering since i'm a newbie on tires, what's the biggest tire i can fit on a pair of CXP 14 Mavic Rims?. I currently use 700x23c. 23-622 from michelin.
I can't help it, did anyone else notice that when he's checking the inside width of the front fork, he's using the wrong set if caliper blades? (He's measuring an inside width with the outside blades!)
Said it before and hope you don't mind me repeating, it is good to hear a presenter from this side of the "pond" presenting GCN information. Thanks for the info, btw, this side its "tires".. not "tyres"...
Gilbert Lopez. There is a very good reason why tyres is spelt with a 'Y'. Have a think about it and see if you can figure it out. Shouldn't be too difficult, even for an American.
@mascara snake Yes, because GCN is a British channel. A quick search tells me the etymology of "tire" is older than "tyre". It comes from how old wooden wheels for carts, wagons, etc. would be "dressed" with a metal band. The band is the wheel's "attire", which later was shortened to just tire. Tyre comes from the 19th century, so it's one of those words that Americans kept the old spelling for.
Didn't know about the hookless rims and tubeless tires only. I've been running 28mm gp5000 regulars on some hookless rims, havent run into any issues yet. Is it really dangerous?
Really old steel and some alloy rims are hookless. You can only really run clincher tires up to about 60PSI on hookless rims without severe risk of them blowing off. The old wheels typically have 27x1-1/4 (630-32 ETRTO, 32mm width equivalent) tires. I'm not sure if carbon is appreciably riskier running pressures that low.
4hours 12 mins to mount Schwalbe ones ( new) on new TR HED jets. Will need a craft knife to get them off. Love the lower pressure comfort but having nightmares about the non sealing puncture! Run tubeless for years. This is the worst fit I’ve ever had
Very fast tire install! I would suggest finish install with snapping the last bit of bead over the rim at the valve stem as this will allow the opposite side tire beads to drop into the rim valley and give less resistance finishing (you may not need a lever).
Mavic rims = great, but Mavic tires are garbage. I made the mistake of trying to ride on the tires that came with my last set of Ksyrium rims, and didn't even get 200 miles out of them before they failed. The sides of the tire were literally disintegrating. It's Continental rubber all the way for me, but those Pirellis in the background at the beginning of the video sure did look sweet.
last week Jeremy you cut steerer tube wrong hight. now in this weeks video you measured front fork internal size with wrong side of caliper what's going down man. not to take the 'p' just an observation. still lovin the vids though. 😊
How fast can you set up a tubeless tyre? Think you can beat Jeremy's time? Let us know in the comments below!
About half an hour with my rims 😂
@Click Bait what about seating? Would the tire become more centred(radially speaking) with no hook?

Can I fit an MTB slick on a roadbike wheel? ( I'm making up a weird hybrid bike for fun🤔🙂)
Great video by Jeremy!
Glad you enjoyed it
#askgcntech 28mm tyres/17mm inner rim width is what I am used to. Why GCN doesn't make tyres' reviews? GCN in espanol has an episode trying several Vittoria tyres at Vittoria's headquarters test track. Not a proper review but it's something, but at GCN I haven't seen that. I use clinchers and had to resort to Bikeradar and the likes to find the best tyres of 2023 and things like that.
hookles tire compatible can be use in the hooked tubeless rim?
I put Conti 5000 Tubeless on my hunt aero 36’s....it took two people to get one of them on the rim.
Nothing mounts properly to my WTB rims - personally I would avoid them. (Bike came with WTB tyres and they are also a pain.)
To get a clincher to fit i have to pressurise up to about 50% over the max pressure.
For tubeless the pressure canister works and helps, but if I get a puncture at the roadside I have no chance.
Hi, Just want to ask 27x1¼ is compatible with 700cx28c?
So, I have an orbea orca that the bike shop installed 28s and the rear barely rubs. another bike shop told me that it should be okay and that there is no problem. Youve mentioned something about frame failure, this is a carbon frame, I'm I looking at frame failure if I only ride road and no gravel? Thanks!
Tried to put continentals on mavic rims and after breaking 4 tire tools I had to cut the tire off the rim. Frustrating and expensive. Oh, and that little exercise took me about 2 hours.
This Subject is never talked about, like it's something that everyone knows about, i need this info so thanks for the video 💜❤
I have a trek grando 520 700x42 and i wonder if i can fit 700 x 22 ? How do i know if i can put a smaller range of tyres on my rims ?
Love this guy
So much good info.
What about manufacturers of tires that aren't true to size? As an example: I've noticed that Bontrager measures true whereas Continental measures larger (23c is closer to a 24.5c) where they're compared on the same rim.
It's caused me many issues with my Noah (2011) with emergency replacements at shops and my wider rim wheelsets when really putting power down. And also as the frame ages.
Dumb question, my 29er hybrid has 37-622 tyres and I want to replace them with some quality ones, (whole bike cost me €120 brand new) the internal rim width is 21mm so how narrow could I go? I'm guessing a 28c or 32c should be no problem but just want to know before I buy online....cheers
Can @GCN or someone PLEASE clarify something in the video? @2:50 Jeremy says "you can only, only, run tubeless on hooked rims", which is then contradicted by the slide after that says you can run tubeless on hookless rims. I understand not putting clincher tires on hookless.
Jeremy is the best presenter on GCN!
I'm not an expert, but I think he misspoke in the first part of these remarks and meant that hookless rims are only appropriate for use with tubeless tyres.
Sticking with tubes on all my bikes, I like the simplicity of tubes.
I used to agree. Now that I can do tubeless, never going back. Tubeless is now my idea of simplicity.
@@dugldoo I've had too many tubeless failures, I'm back on tubes again.
@@bensaund Sorry! What happened?
@yo dugldo Two blowouts, and too many punctures which don't seal. I've gone through 7 tyres this year. Gravel Kings were useless, pirelli useless, so gonna try something else.
@@bensaund Not good! I've ridden thousands of miles of gravel on tubeless GravKingSKs without failures. Why not see what the winning riders of Unbound used and go with their success?
I'd pay good money to watch Jeremy try that with a Conti TL5000 against the clock.....
What would be the widest tire that I can install on a 19mm 700 rim?
So if I got this right, I can use my clincher Zipp 303 Firecrest (Rim brakes) with Tubeless tires? Would you recommend it? #askGCNtech
Martes
Do you think a 43 mm Panaracer Gravel King on a 25mm internal would fit on the Grevil?
I would love to see the bloopers at the end of the video - 3 tyres tried, broken plastic tyre levers, sealant over the floor, repeated (unsuccessful) inflations
Bleeding fingers, remote chucked across the room, swearing constantly. Oh those are my bloopers
Hey Jpow have you ever put GP5000 TL on those mavic wheels? I couldn't do it
Hey J , your using your calliper wrong or should I dare say Vernier ! Those edges you used are for outer diameter and the little ones on the other side are for interior diameter. The way you used it I would say you lost about an inch !
I'm looking for a rim that best suits my 38c gravel tires, what's the widest/best rim I can put the tires in? because I heard that using wider rims for your tires can lessen the contact point of your tires to the road. I'm looking for that flushed aesthetic as well
I Dont know i had a 19 mm rim with a 23 c tires and looked like a bulb but then i got 23mm rims and looks good but i dont notice a differen but that 19 mm rim i put a 35mm tyre and is too much the tyre is too soft needs more support (a wider rim) i think think the best is to use the same size of rim and tyre. But for road depending of the pavement a 23 is not enugh i like 28 in the rear snd 23 up front
I don't see the link for 3T mentioned in the video, in regards to their research on WAM and RAM for tires.... Am I missing something?
Yes I miss the link also.
Is this it? blog.3t.bike/2020/06/14545/gravel-tire-dimensions-explained/ It appears to be only for tires of gravel bikes...
Sorry guys! This is now in the video description!
Nice documentation but that's only for gravel bikes and tires.
I used the link in the video. It went to site that said WAM RAM research would be in part 2. Where's part 2?
Can I fit a 700cX28 Vittoria inner tube & tire on a Roval 23mm rim??
You can but ETRTO standard is a buzzkill and doesn’t recommend it.
Good info if you're an auditory learner... lol I'm off to find a chart I can look at.
Galen, just ask Jeff W, I'm sure he'll have a spreadsheet ;-)
Will 700*23c fit in place of 700*25c?
presenter challenge: mount new tiers on a rim. new as in take it out of the box and fold it out.. and THEN mount it. it needs to be aligned with he valve as well. tubes or tube less is up to you
The internal rim width to tyre width stuff confuses me a little.
I always see people talking about fitting tyres on a wheel that'd a narrower internal. Rim width. Is it possible to do the opposite?
For example, I have a hybrid with a 30mm width rim, could I fit a 25 or 23mm tyre on it? If its possible but just not ideal, what would be the problem with doing it?
It wouldn't be safe as the tyre wouldn't properly cover the rim :)
@@gcntech I feared that was the case. It's super annoying, I wanna put the bike on an indoor trainer but there doesn't seem to be anyone that produces 30mm trainer tyre, everything is either 23 or a mtb tyre
Continental GP5000 TL doesn’t go on a Mavic Cosmic Pro Carbon UST rim.................gone back to Mavic Yuksion UST pro but looking for other suggestions
The bike is solid and my Ebike conversion went great. ruclips.net/user/postUgkxHL1v1R3NE5x4KiYfyt8dnQmyNYz7qi5L Very smooth ride at 30mph with no problems (135 miles ridden so far). The picture is a bit deceiving - there is WAY less space in the center of the frame than it shows. The suspension connection takes up the entire thing. So I needed to attach my battery on the bottom of the frame and my controller on the top. Instructions for assembly were lacking but honestly it wasn't too hard to figure out even though I have very little bike knowledge. Watched some youtube videos on adjusting the disk brakes but that was it. Still, I am loving it and very happy with the purchase.
I have no idea how wide my rims are but I run 25mm tires. What size tape do i need if i want to convert to tubless?
can i put a 23mm on the same rim that is used for a 28mm tyre?
pls help
I was wondering since i'm a newbie on tires, what's the biggest tire i can fit on a pair of CXP 14 Mavic Rims?.
I currently use 700x23c. 23-622 from michelin.
I can't help it, did anyone else notice that when he's checking the inside width of the front fork, he's using the wrong set if caliper blades? (He's measuring an inside width with the outside blades!)
how do i know what size rims my bike can take
Said it before and hope you don't mind me repeating, it is good to hear a presenter from this side of the "pond" presenting GCN information. Thanks for the info, btw, this side its "tires".. not "tyres"...
Standards of the channel set by the studio in Bath for uniformity I guess lol
Gilbert Lopez. There is a very good reason why tyres is spelt with a 'Y'. Have a think about it and see if you can figure it out. Shouldn't be too difficult, even for an American.
@mascara snake
Yes, because GCN is a British channel.
A quick search tells me the etymology of "tire" is older than "tyre". It comes from how old wooden wheels for carts, wagons, etc. would be "dressed" with a metal band. The band is the wheel's "attire", which later was shortened to just tire.
Tyre comes from the 19th century, so it's one of those words that Americans kept the old spelling for.
Didn't know about the hookless rims and tubeless tires only. I've been running 28mm gp5000 regulars on some hookless rims, havent run into any issues yet. Is it really dangerous?
Really old steel and some alloy rims are hookless. You can only really run clincher tires up to about 60PSI on hookless rims without severe risk of them blowing off. The old wheels typically have 27x1-1/4 (630-32 ETRTO, 32mm width equivalent) tires. I'm not sure if carbon is appreciably riskier running pressures that low.
4hours 12 mins to mount Schwalbe ones ( new) on new TR HED jets. Will need a craft knife to get them off. Love the lower pressure comfort but having nightmares about the non sealing puncture! Run tubeless for years. This is the worst fit I’ve ever had
Tooooobless tyres. YEEEEHAH!
4:30 GCN does dubstep.
Very fast tire install! I would suggest finish install with snapping the last bit of bead over the rim at the valve stem as this will allow the opposite side tire beads to drop into the rim valley and give less resistance finishing (you may not need a lever).
Why would you messure that fork in the intro with the wrong side of the vernier? How do I trust anything that this guy say now?
AND HE DOES IT AGAIN DURING THE VIDEO
To messure internal distances or diameters use the back things of the caliper
Wow, if it only takes 38 seconds to mount, I may also go tubeless. I got Mavic
Mavic rims = great, but Mavic tires are garbage. I made the mistake of trying to ride on the tires that came with my last set of Ksyrium rims, and didn't even get 200 miles out of them before they failed. The sides of the tire were literally disintegrating. It's Continental rubber all the way for me, but those Pirellis in the background at the beginning of the video sure did look sweet.
The internet is a magical place. Jeremy records a video about "tires" that is then effortlessly streamed as "tyres."
last week Jeremy you cut steerer tube wrong hight. now in this weeks video you measured front fork internal size with wrong side of caliper what's going down man. not to take the 'p' just an observation. still lovin the vids though. 😊
Too much coffee.
