I have a CT1 B-stay (2003). Will a 25c tire fit? I'm considering a Conti Ultra Gatorskin. Thanks.
yes; I've done it (size 54 C40, at least) nmDougSloan

I can kinda see a 200+ pounder using a 25c for comfort and the ability to run slightly lower pressure, but a guy on a 54cm frame isn't gonna generally be that heavy. Unless you were doing loaded touring (unlikely with a C-40) I'd think a 23 would be more than fine.

I always run 700 x 25 (Contis) and I weigh 145. Fewer flats, more comfy, more durable, easier on your wheels, better on rough roads or dirt. I think they are ideal for recreational riding and training.

I bought a C40 frame with HP stay about two months ago. When I switched my wheels from my old bike to this frame, I had 25C tires on the Ksyrium rims. I usually ride 23C but I mail-ordered these tires by accident. It was no problem when the tires were on my Trek, but when I put them on the C40, there were very little clearance between the tire and the seat tube. There was also very little clearance between the tire and the top of the front fork.

First time I went out on a club ride with the Colnago, the bike rode OK until on the way back. We went through a newly resurfaced road where there were a lot of left-over resurfacing gravel with the sticky black tar. Well, these gravel got stuck on the wheel, and they didn't make the clearances. Oh no ... the paint on my brand new frame!!!

I don't know about the profile of the Conti Ultra Gatorskin, but my Vittoria 25C was just too high.

thanks. i've come to realize i'd rather have bigger tires on the rough pavement than continue to change flats, esp. since i don't race.
