Let's take a proper clincher, Veloflex Master 23....(snipped text). Any thoughts?
I have only just started riding tubular tyres (six months ago) and have mounted no more than 4 sets, on two separarte wheel sets, add/remove etc ...
My first set (Challenge Strada on Nemesis rims), not so good, a small bump (radially out of true, introducing the bump) and slightly twisted (not noticeable). After a handful of rides I removed the tubs, reglued the rims, trimmed around valve hole and replaced. Used a bit more glue and mounting was better, had more time to position the tyre, not perfect but heaps better, tiny hop in rim not noticeable, 1-2mm twist again, nothing to worry about.
The second set (Veloflex Criterium on Enve 6.7 rims) Went like a dream, No hop, 1-2mm twist.
The next set again went well, no hop or twist.
Now, I may be lucky but then I may just think about each stage as I am doing it and work out a way to do it better next time.
I was guilty of using a tiny smearing of glue when mouting and it left me no time to position the tub when trying to move it into final position. Don't get me wrong, I'm not using so much so that it splurges out of the sides when the tyre is inflated but enough for it to smoosh about a bit easier than if I was using a very thin layer to mount.
Had no problems at all.
I'm a tubular convert.
I still keep a set of clinchers for emergencies but I can honestly say they have not emerged from the wheelbag since I started riding on tubular tyres.
There is no comparison to me and I used to ride good clinchers (Vittoria Corsa SC) on (Vittoria) latex tubes.
Tubular tyres may take a bit more work to mount than clinchers but once on take probably less looking after than clinchers. I puncture in 2,500 miles. Swapped out for a spare at the side of the road, took about 5 mins and I was up and going again.
