RobertWhitehead Posted March 5 Share How many links does your current chain have? You may get away with a 34 without having a longer chain but 36 may cause the rear mech to over extend. Do you need a 96 or 104bcd ring ChrisF 1 Link to comment Share on other sites More sharing options...

Robbie Stewart Posted March 5 Share I learnt that fitting a 2.25" tyre back to front on 36mm inner width rims, and then trying to remove that tyre to fix the rotational direction is a mission. It sticks to the bead like no one's business. I pulled the 2.45" Minion DHR 2 off with my bare hands yet this new Racing Ralph won't let go regardless what I try. I can't even get a tyre lever under the bead. ChrisF 1 Link to comment Share on other sites More sharing options...

Sometimes the feeling is so bad that I pretend to not notice my mistake until the new owner points it out and offers to fix it DieselnDust, Danger Dassie, ChrisF and 1 other 1 3 Link to comment Share on other sites More sharing options...

I can't even get a tyre lever under the bead. I don't even know how many tubeless tires I've fitted ... And I still get it wrong now and then, case in point last week. Front wheel on my gravel bike .... Thought stuff it I'll just ride it like that, rode it once. Yesterday I swopped it around but ... Unlike the first time it didn't just inflate first time 😤 ... Took some effort Lesson learnt, it'll probably happen again AND just because the first go was easy doesn't mean the second time will be!

The front tyre would NOT seat .... I re-did the rim tape twice. Double layered. Eventually gerry-rigged a setup whereby I had a straight pipe from the compressor to the valve. After all this agrivation the rear tyre slipped on like a glove. At least now I have a "jig" to get more air quicker to those troublesome tyres ...

Are you by any chance using gorilla tape instead of proper rim tape? Robbie Stewart 1 Link to comment Share on other sites More sharing options...

Definately not Gorilla tape then, sounds like the normal bog standard plasticky nylon rim tape commonly supplied. Link to comment Share on other sites More sharing options...

I can tell you this about that rim tape though. If you get even a slither of it between the bead and the rim, good luck trying to pressurise the tyre. Discovered as much during a ride at Banhoek. I had to bodge a fix with a plier, a pocket knife and a CO2 bomb. I still managed to finish my ride at least.

I've had to unseat a bead with a block of wood and a hammer before today, so know that you're not alone. Link to comment Share on other sites More sharing options...

Saturday's jobbie went silk smooth, no chance to use my new toys .... if you put a ratchet strap around the circumference of the tyre it limits the tyre expansion a lot and then from there the tyre inflates sideways first pushing the beads outwards. This often helps get tricky tyres to seat. There are youtube videos how. thebob 1 Link to comment Share on other sites More sharing options...

But the new owner is NOW lining up for her first race on the Green machine. All the troubles forgotten, now for the FUN to start.
