I have some conti GP 4000s II tubs to glue to carbon rims. Most sites talk about multiple layers of thin glue, but the conti video and instructions suggest on coat on rim and tyre, leave for 12 hours, then another coat on tyre only and straight on to the rim.

I guess I should follow manuf. instructions over anything else but it seems to go against other advice.

Anyone know why?

For tri I tape. So much cleaner and easier. takes 20 minutes to do both wheels and off you ride! Its better having a pre taped spare also when needing a quick change on the road. Tape is very good these days.

For my track wheels i use a track cement though but the process is basically 2 thin layers on the wheel (wait 12hrs or so to dry between each). then a layer on wheel and tub, then another wait, and finally another thin layer on wheel and tub and fit. so 4 wheel and 2 on tub

Yes, another tape infidel here too. Always have.

I'm currently preparing a spare for another season of longer events; it's sat on a spare Zipp wheel (we've all got those right?) pumped-up, and I'm hoping the tape comes off with the tyre as normal! (Velox #76 tape).

Velox do 2 types of tape now. #14 (clear with a weave in it) & #76 (the white thicker orig version). The 14 is thinner and supposedly will stay on the rim when you remove the tyre as it's really adhesive (not tried). I have my Zipp SLSpeeds on my main race wheels with this stuff, and my spares with the thicker soft white tape. No issues with either tape.

If I was riding supported road or track, I would glue...but I don't.

For some reason I discounted tape, not sure why. Certainly seems easier and quicker. You have all done it and not died so there's that!

Ill get some tape and give it a go. Technique seems to be apply to rim, leave backing on, install tyre then use pencil to lift and peel backing tape?

Thanks

Yes. Just make sure it's properly centred every so often, as it's easy enough to move it back off the tape with the pencil; not so much after you've finished and thrown 140 psi in it to 'set' the tyre.

Glued a 24mm zipp tub on a xentis rear last weekend, it was nearly new so no need to stretch.
Just followed the you tube guide.

Filled with sealant.

Simples.

That was a complete disaster. Despite them being stretched for 4 days I couldn't get the bloody things on. Covered in blisters now.

Gave up and took them to the bike shop. Life's too short for that!

Means I wont have them for next weeks race but such is life.

Conti clinchers can be really tight, I guess their tubs are the same. Never bought Conti tubs, as their reputation isn't as good the clinchers, and they only use butyl tubes too.

Good to know for future. I was given a Evans Gift card from work and they were the best they had in there. Next time will research a bit more and buy something better.

The Vittoria I bought as a spare went on really easy.

At least with the Contis I know they wont roll off as the force required to get them on dry was huge Smile

I use Vitoria Corsa CXIII and no probs fitting. The Sonderklasse on track wheels were a little tight but not too bad. Had bigger probs fitting marathon plus clinchers on my fixie Wink

I would usually stretch two contis on my race wheels over the winter (not having spare carbon just lying about) ready for a new season...the previous seasons become the spares and a really old one is tied under the saddle for emergencies...

Always used glue...a big mess of it usually because I lack the patience required to do thin layers

It also helps if the tub is completely flat/empty when you mount it, as even a little air can make it more difficult (decreasing the internal diameter).
