I am thinking about riding in some criterium (road) races. My road bike has a relaxed geometry -- the write ups and reviews all say "this thing is excellent for long, hilly rides, but just don't take it to your local criterium."
Instead of dropping serious cash on a more race-specific road bike, I'm thinking of riding my cross bike with slicks in the criteriums. I've ridden it on the road with slicks before, and it generally handles well (with a small and occasional fork chatter issue on some big decents if I use the top-mount levers, but there aren't big decents on criteriums). The higher bottom bracket should be good for the tight corners. Tire clearance, cantilevers with top-mount levers, and cable routing all seem to me irrelevant.
Has anyone tried it? Am I setting myself up for a big crash (or poor performance) based on something I'm not seeing here?
