so, why are track bikes fixed gear? is this a rule in track racing? if so, would track racing benefit from the introduction of multiple gear bikes(hypothetically)? would speeds increase and times go down? if not(a rule), it must be advantagous to use a fixed gear b/c that's what track racers use. anyone know why?
as a sidenote, are there any good resources on the internet for either history of track racing or theory and strategy? thanks.
