Easy, Fast, Straight. How to Mount a Tubular Tyre
Вставка

- A tried and tested method for mounting a tubular tyre that I have been using for over 10 years without any issues at all.
Easier to get the tyre straight if you apply the tyre to damp glue on the rim, and let the pressure do the work.
Tyre = Vittoria CX Corsa Isogrip
Pump = Bontrager Turbocharger HP

A couple of tips to help. I've been on Continental Sprinters for about 15yrs, 5-10k miles.
I take em new and slip them onto an old rim. Keep em till I wear the last one out, then they're a bit easier to mount.
I run a bit of Slime ( car stuff ) in all mine and it's magic for small punctures. Goathead thorns abound in my winter riding area.
Once I've got the tire glued and onto the rim I take a thin tire lever or a smooth round screwdriver and insert it between the tire and the rim, then pull that around the perimeter, letting the tire center itself quite nicely.
I use my old tire as a spare if it's still ok, just worn thin. I found a seat bag ( Tri sports brand) that perfectly holds a tub folded in 3rds and taped tight.
If you ride concealed spokes, true those while you can😊. I find the tape mount to leave a mess and destroy the tire as you remove it. Hope that's constructive advice.
I bomb descending, why I ride tubbies. I've flatted clinchers and ended up on bare rim...not good.
The pro mechanic that I have watched glued the rim first .
Everyone has different ways of doing it. I prefer a damp rim to be able to move the tyre around.
Replacing my first tub at the moment and i've watched a fair share of videos in order to get it right, i would say i like yours the best. Good energy and knowledge! Cheers.
Nice of you to say so, many thanks!
Hi, I just wanted to say that I seriously believe this is one of the best cycling channel available online!
Thanks mate, that's nice of you, but I don't think that's a unanimous decision!
Maybe it is a bias coming from a maths guy who appreciates a scientific engineering approach :-)
Btw, what do you think about training on tubolars? I am an italian living in the UK and wherever I am, roads are not the best. I am a bit worried of going with tubolars and I guess that the repair kit you would have to carry during training would outweigh the weight benefits of tubolars right?
So, would you say: train on clinchers and race on tubs?
Also, what do you think about recent "scientific tests" (such as the bike radar one I think, or maybe it was the cyclingweekly one) that apparently deem clinchers as faster than tubs?
Cheers mate,
Ciao!
Hi Carlo,
I ride tubs all year round, but then we have quite smooth roads. I know the UK has some pretty poor ones, but having said that, tubs (and I quote from Vittoria's website!) are better at absorbing shocks than clinchers.
All I carry is a small foam aerosol which works in most cases and it's very rare I puncture anyway (again road quality, and being careful where you ride). So given that you have to carry a spare tube or puncture kit with clinchers, it's a wash.
I think that BR test was a bit of joke really - just one close car pass would change the results in either direction. The difference they are looking at is like 1 to 3W, which is simply not detectable in open road testing.
But a top clincher will outperform a poor tub, and vice versa, so it's mostly down to which tyre make and model you choose.
Cyclespeed Tours you almost convinced me! which tubs would you reccommend? i have heard tufo are quite good? i mean as a balance of performance and puncture resistance..
Seems Tufo don't do that well in Crr tests, if that's important to you...I really like Vittoria CX Corsa IsoGrip (not the EVO, that's the old model, slippery in the wet).
I can get them for 35 Euros, and they are a great blend of Crr, weight, wear, grip.
Veloflex are nice too, I go for the 'Carbon' model, but more expensive.
I prefer the velox tape, easier to work with and is less subject to going hard with age, + i like the real italian tyres, veloflex. Should give both a try. Works very well. Run tubulars on every bike i have for all rides. Veloflex are the easiest to mount just like a lacky band
I did try tape but didn't really get on with it, although I must admit I didn't persevere too much. I've used a few Veloflex over the years, notably the Carbon, and yes, very good, I like them, but I can get Vittorias way cheaper. Nice to hear from another fully paid up tub user!
do you not stretch the tub overnight before you glue it?
3:31 "for the next part of this video we're back in Britain so we'll carry on here in France." lol.
Well spotted I never noticed that. Must have been high on glue fumes!
He said Brittany!
I got a set of mavic ccu tubulars after seeing your videos! I love the feeling of the ride, they feel so smooth also descending feels much better on them as on my clinchers. There were some mavic tubs fitted with a tubular glue tape, but i want to fit the next wheels with glue. What if some of the glue gets on the breaking surface? How would you remove it? cheers
Acetone. It won’t harm the carbon
Is tape good enough for quick fixes? Otherwise i think ill go with clinchers on grouprides.
Yeah tape works.
Hi, I've a tub that has come unstuck around the valve (I've not ridden it for 18months). Do I have to remove, reglue the whole tub or is there a way to patch the bits that appear to have partially come unstuck (something certainly makes that clicky sound on every revolution you mention) ? Thanks for the video and any reply.
Unfortunately, the only way to do it properly is to remove the tub and re glue. I've had this happen to me before and it's annoying! The way to avoid it is to be extra generous with glue around the valve area and really seat it well there.
@@CyclespeedTours thanks. What's the best way to clean the underside of the tubular before application of glue it do you just reapply over the top. This is all new to me (i ever bought the conti carbon glue but see you use alu. Glue from the comments below). Would one coat on each surface suffice for reapplication? Only asking as time is tight:(
@@tinnitusuk The alu glue is stronger. And you can just reapply over the top yes, no problem, one coat each.
Hows the crosswinds or sidewinds on those lightweight wheelset? Are they really sensitive to wind? Im getting the same wheels maybe next week. Tubular
I don't find it a problem at all. And that's up to about 60km/h wind. Sure the bike can twitch a bit but it's never been a major issue. None of my deepish whelkiest (45 - 50mm) are a problem in the wind, but I guess it depends a bit on how comfortable you are with your bike's handling.
get am external threaded valve extensions and use the bolt and you wont get a lose area where valve is
Agreed, have this on my Campag Bora One with conti and veloflex tubs.
Hi! When mounting the tire, how much time do you have before the glue has dried too much so you can no longer wiggle the tire around to get it straight? Seconds, minutes, or maybe hours?
Hi, not much more than a minute before it starts getting tacky. Of course, it's OK if the glue dries, but I just prefer it when I can move the tyre around.
You can use Tufo glue tape is easier and there is no waiting time.
@@CyclespeedTours this is the bit I found tough to get right. I mounted the tyre immediately but found it really difficult to move and align it as the glue bonded so quickly. Never managed to get it fully straight even after full inflation but it looks reasonably ok. I wonder if the pro mechanics obsess over getting them straight or does it really matter?
@@dickieblench5001 If the glue on the rim is fresh, it should still be able to move. Straight is definitely good from a performance and aesthetic viewpoint. Don't forget to pump as hard as your pump can go.
Any tips on a really tight tubular, I've just bought some Maxxis Relix, it's like they are way too small, pumped the tyre up overnight to stretch for dry mounting, can't get it on. I am physically strong, physical job, lift weights but feel like the wimpy guy from the Mrs muscle adverts 😂
I've never used Maxxis so can't say for sure, but they should go on! You could be an Olympic weightlifter, but that means nothing if you have weak thumbs! Any sort of manual labour helps to build finger strength, keyboards and Iphones don't...! Really pull it hard with both hands when you first apply it, and keep pulling with every new grip, every few cm.
@@CyclespeedTours I kept stretching my tyre around my back, feet everything, it eventually went on dry, really hard to do. Now being glued up with first coat. Thanks for getting back to me. I might actually build I tub stretcher.
@@mickchaganis6607 Good idea! Or just buy Vittoria!
@@CyclespeedTours just letting you know, I put the tyre on the radiator til warm, stretched it by hand, holding it about 6 inches apart and pulling all the way round, warmed again, did it again, then let cool as I was worried the glue would set too quickly and stretched again just before mounting, it worked well.
@@mickchaganis6607 Good thinking!
HI any tips on how do you repair a small leak on tubular tires? i just got new tires less than 50 miles on it.
Ah, that's annoying! I'm pretty sure a foam sealant would do it. You could even just remove the valve core and pour some liquid latex in, swish around, then pump up. As long as the hole's not too big it should be fine. I've ridden tubs for thousands of miles after doing just that.
The bontrager pump =red
What is the silver one?
It's a Leyzne Sport FD, also very good.
I know the video 2 years old I let my stretch out over night on wheel didn't make a difference .man was a freaking bitch but at the end it worth it
It's OK, I'm still here! Was it a Conti? They are tough. You can also manually stretch it by pulling it in your arms if you're strong!
@@CyclespeedTours no actually it was veloflex.
It would be great if the 'dislikers' would explain why or what they dislike - I'm all for an open debate on the different ways to mount tubs.
6 people ride tubeless only.
You own a lightweight wheelset? :o
Er, yeah, but I got a good deal on it! LW's are for life right?! Your Avatar picture had me trying to get a hair off my screen....!!
Worked for me🤘
Nice video. Man, that’s a tiny cassette you have on those Lightweights
Thanks! Yeah it's a 23-11, but I would put a 28-11 for the Alps.
how do you live in a castle? is the tour business that good?
I can assure you, it's definitely NOT down to cycle tours!!
No..Placing your bike up side down??
I know, the things I'll do for my subscribers, right?!!
Hi.
1.Do you use a yellow Conti glue (for an aluminium rim) , which I see in your video, on a carbon rim? There is a black one for carbon rims.
2.How many layers do you apply on a rim and how many on a base tape ?
BTW great video, congrats !!!
Thanx
Thanks Kamil, Yes I do use the yellow one, as I find the black isn't strong enough, and the yellow does not harm the rims.
If tub is new, then 1 layer. If rim is new 2 layers, otherwise, just 1.
So you did not notice any change in base tape position on a carbon rime using the yellow Conti glue ?
I want to switch to Vittoria as well as to using a glue as I have bad experience with rim tapes /TUFO/ - recently my Tufo Elite Pulse tube got displaced on a rim /glued by Tufo rim tape /. I live in Czech Rep. where TUFO is the most common and accessible local brand for tub users.
On the other hand TUFO extreme sealant works well for punctured tubes. Here is my little tip: I tend to apply a sealant using a syringe directly through the puncture hole into the tube, thus avoiding the hassle with undoing a valve core. Just like a nurse in a hospital .
Many thanks for your great tips and tricks!
No, no base tape movement. The yellow glue is the stronger one of the two. Good tip for the sealant - I use foam cans if I puncture.
Hello,
Thanks for the vidéo.
So if i well understand,
1- glue on tube
2- let it overnight before installation
3- glue the rim with one layer and install just After the tube.
3bis- glue the rim twice if it is a new one
How much Time between the 2 layers ?
Is tubular good for hot climate, like 35°Celcius ?
Thanks
@@CyclespeedTours i spent ages prepping my rims, removed old tubs and the tyre tape stuck to the rim, had to buy glue remover and sand it off and scrape it off with a flat head screwdriver for ages. I have literally just put two layers of glue on my rims and one on the tubs and looking to do a 3rd layer tomorrow following advice from other clips, next time i follow your advice and just do one layer on rim and tyre
Great video again... True the Conti tubs are best mounted by a bodybulder and honestly they aren't worth the trouble (but I did later read you are supposed to pre-inflate first). Have you tried Soyo Tyres?
I clicked on the video ( I already know how to mount a tub) because there was "fast" in the title. But fast is far from the reality of your video. Pre-inflating so you don't have to fight the tyre and using tape instead of glue may be the "fast" way. Anyway with the negative stuff out of the way I want to know, can the Lightweight rim handle 8 Bar? Not all carbon rims are capable of high pressures, I don't know Lightweight as I don't have the cash to even consider them as an option. Perhaps a note to the people who are less informed should be "adhere to the rim manufacturers maximum inflation pressures" no pun intended.
Any way chapeau on you cycling channel great topics and great content!
Thanks Simon, yes, as Conti don't seem to do that well in Crr tests, I tend to avoid them anyway, and I can get the Vittorias cheaper. It would help to pre-stretch / pre-inflate the Contis.
I think my method is 'fast' in comparison to other methods which seem to apply countless layers of glue, and leave them to dry for days. Not necessary IMO. But tubs are always going to involve some time investment.
I take my tubs up to 10/11 bar when I mount them and tend to ride at 7 bar. I've never had any issues with my LW's over 5 years or so. I think clincher rims may be more susceptible to pressure limits.
I tried tape once. Never again!
No not tried Soyo tyres - are they good?
The Soyo's are more popular in track racing but they do have some fantastic road tyres too. The main thing they do better is the construction technique. They have a range that are seamless, the casing is woven as a loop and not a tube so there is no join stitching or overlapping. The ride and feedback they give is superb. I have low end carbon tubular rims and when I got them they said not to inflate over 120psi or 8.2bar so I was just curious to know if all rim manufacturers were giving similar pressure limits.
that glue was shot !
Macspud28 he said britanny not Britain
I just use 3M 77, far far faster.
Thanks for the tip
do you not stretch the tub overnight before you glue it?
No need with Vittoria. Continental and others are harder to get on, so maybe some benefit.
Yeah. used to always do it with contis. 3 day job to fit them, day 1 stretch, day 2 coat Base tape, day 3 glue it on day 4 ride.
