Singlespeed cyclocross question...(3 posts)

Singlespeed cyclocross question...Colin S.
Aug 22, 2001 11:50 AM
Hi. I'm thinking about building a single-speed 'cross bike with a Surly frame. Anyway, what's a good gear ratio to start with? I was thinking 36x18 or so... Also, should I use 170mm or 175mm cranks? I plan on riding offroad as well as doing a few road rides with the road team. I have a Redline Conquest right now, but I'd like something steel (not so harsh off-road) and a little simpler, since I only use ~ 3 gears on any given ride. Plus I'd like to be able to run 40c's. Anyway, has anyone done anything similar? I'd really appreciate any advice. Thanks!

for what it's worth I used to run a 38-17 last year om my SS CX bike. I found it pretty good for races, not so much for off-road MTB type riding so more of a 2:1 ratio would be better for that. As for cranks, I used 175mm which is what I have on all my bikes. Road riding on a single? You'd need to change out for a big ring I would think, that sounds painful.
