Tubs

Well, it's OLD and has kind of peeled away at the edges a bit so I'm sticking it back down with Copydex.

FUN!! 🤗

Tub n00b question #94

Been Copydexing the base tape back on my tubs. Just the very edges where it was peeling away. What do people use to hold the tape onto the rubber while the glue is drying? I turned the tyre inside out which seemed to do something, but I've also read pumping them up on an old rim helps...

Glued a tub on last night and it's gone down overnight. I'm 99% sure it's down to a poorly installed valve extender (by me), because it was hissing a bit at the valve when pumped up to high pressure.

The question is: if I rip it off again tonight and fix the problem, do I just need a quick layer of wet glue on the tyre before refitting? Please don't make me strip it and start again.

Is there a forum recommendation for under 23 width tan walled tubs? I've got a 23 Vittoria rally glued on the rear of some new (to me) deep carbon wheels that just about binds on the non drive chainstay of my beautiful TT frame on the rear. I was thinking about getting the same in 21 as it is cheap, but open to suggestions.

PS. Dbad

Rallys are fairly terrible tyres. Almost anything else will be better.

For aluminium rims, Conti recommends four coats on the rim and two on the tyre. Seems like a lot? I'm not sure my tube of glue will stretch that far...

I've always gone with three on the rim and one on the tyre - use Vittoria Mastik #fuckconti

Why am I supposed to be fucking conti? I've got the actual glue now anyway so...will go with 3 and 1

You wait until you need to take a tyre off the rim......

Because it'll be difficult? I'm sure I'll live tho.

removing tub glue from carbon rims. I've tried white spirit and acetone and it's just too thick and stubborn.

Effetto Mariposa make this http://www.wiggle.co.uk/effetto-mariposa-carogna-tubular-tape-remover-150ml has anyone ever used it?

I've also seen reference to epoxy remover http://tfalin.blogspot.co.uk/2009/08/how-to-remove-tubular-glue-from-carbon.html - has anyone tried that with any success and can recommend a brand?

Schwalbe makes something (dunno the name) worked wonders for me

That Mariposa stuff is ace, but I needed at least two goes of it on very old/thick glue.

thanks, so for two wheels I'd need two tubs of it?

Nah, I found one coat was about 30ml or something. I actually noted it on my bottle. Let me see...

thank you

I have. It was the only thing I've found that has ever worked. Let it soak into the glue for a good long time, but don't let it dry out.

New to this thread. I now own a track bike with tubs.

Is there a beginner's guide to this? I have no tape, no glue, no brush, no clue and no spare tubs.

Also, thankfully, no puncture, but unlike the above matters, that could spontaneously change.

I have all of the above, and more spare tubs than I know what to do with - you could always pop round.

Warning: I will fill your pockets with parquet when you are not looking.

Used vintage Continental Special Rim Cement to put a tub on the alu rim of the HED Pro-Am. now my hands are stuck together.

Is this stuff safe for carbon? Got the zipp and the corima needing a tub too.

If it's only a matter of heat, I doubt I will be descending or braking at high speed. This is poseur kit.

That's true,

"consumer tubulars" have butyl tubes.

Team issue race tubulars, Competition, tempo, Sonderclass have latex tubes.

There is a difference in the ride and also unsurprisingly in the air retention time .

Cheers Neil, I shall do so!

This is, at best, a half-truth. Most of the team issue Continental tubular tyres ("Pro Limited" and friends) habe butyl tubes. These tyres are finely tuned to special applications. Continental's researchers believe that (their) properly formulated butyl tubes are superior to latex. The standard competitions (and ProLtd) get a very thin buytl inner-tube ( 0.4 mm).

In order to, however, meet the wishes of some riders (and their mechanics) Continental also make some of these tyres with latex.

Have you really compared ProLtd latex with ProLtd (non-latex) designed for the same event?

Forgot about this, but I just saw the bottle which reminded me that I used about 5-10g of remover per "go" on each rim. And a heavily glued rim needed 2-3 goes.
