Going to race my first season of cyclocross this year. I'm trying to get a bike together to ride SS. I'm thinking of setting up my work bike for it..... Its an urban/light tricking frame, and is pretty sturdy...it has that extra trick lug thing under the downtube/headtube. With the rear wheel pulled far back in the dropouts, it will definitly fit atleast a 35mm tire. With the stock fork it barely fits a 25mm though. Its currently set up fixed/fixed, 46/19&17 brakeless. I run SPD MTB pedals. I have a set of cheap fixed/free wheels laying around....the front is machined.
I plan to put use a C/X fork and cantilever brake up front. But my issue is the rear. I don't really care about messing up the finish on the rear wheel (non machined).....But the frame is drilled for short reach road caliper brakes. Is running just one brake UCI legal? Or even advisable? Will I have issues running a short reach brake? How narrow of a tire will this limit me?
Oh and I can't seem to find anything good on gearing for singlecross. My gearing is already low for the streets, but i imagine it being a bit steep for cross.
