I never raced on a track. We didn't have one. I have now acquired a 70's era Frejus track bike which I'm building up. The chain is much beefier than road chains and the chain ring (Campy) has big teeth that are widely spaced. Is this all about stretch - providing a transmission that does not have any give in it? Or is there some other reason for the big chain and different chain ring?
