devils haircut--take steroids.
if you don't have a body that builds muscle easily, you're going to have a hard time at track racing. just saying...you will not win many races when you are going up against people who are jacked.
Also, just b/c you ride a fixed gear bike on the road doesn't mean your technique is good...at all. I recently went to a velodrome in Dallas (after riding a fixed gear bike in the street) and was surprised by how bad my technique was according to the coach and some olympians.
