Tubs not gluing – Any tips?
Yeah its only a fine coating on each pass, no huge lumps or anything, balls! just looks like crap glue, should have researched a bit more but thought non-carbon glue might do something daft to the rims or something.
Being CX tyres I wanted to run them pretty low, at the mo’ they look like they’ll just rip straight off the rim on a grassy corner.
Back to clinchers for Sunday, I’ll get some Vittoria on order for the next go.
Any tips as a cleaning agent?Posted 4 years ago
1. New rims new CX tyres
2. Inflate tyres and stretch for 24hrs
3. Even spread of glue around rim + tyre – left for 24hrs
4. Even spread of glue around rim + tyre – left for 24hrs
5. Glue around rims, mount tyres as soon as glued, inflate to 40psi leave for 24hrs
Came home tonight and pulled the straight off the rim as if they’d not been glued…
Carbon rims and tub glue FWIW.
Should I remove all glue on the rims and start again or redo the laying process?Posted 4 years agoMulletus MaximusMemberBlazin-saddlesMember
You can use a half round file to get the thick off the rims, the Conti carbon stuff just peals off anyway, I think it’s designed to not stick very well to save damaging rims when taking tubs off, I want them stuck on TIGHT for cross and crits!
I’ve been using the non carbon Conti glue on cross and road tubs for 10 years and like I say, use the method you did before and they’ll not come off without a fight.Posted 4 years agocrispycrossMember
You may well need lots more glue. When you pulled the tyre off, did it look like it was stuck across the full width of the rim or just at the edges? Check the fit of tub on rim. If the rim’s too deep and it didn’t touch in the middle, you need to fill this gap with a 1/2 width old basetape or similar. Not rim tape because you’ll never get the original glue off it.Posted 4 years ago
When you’ve mounted the tyre, put 1 bar in or so to give it shape, wrestle it straight then let all the air our and roll the wheel over a broomstick or dowel, 2 or 3 cm diameter, putting your weight on it to really push the tub onto the rim, especially in the middle. Put a bar or two in to get the shape back and leave overnight.
