Hi all I'm looking to change my 52/39 chain set to a compact. Can I just buy new chain rings and adjust the front mech accordingly
Chances are your chain set will be a 130BCD which won't take a compact chain ring set. For a compact you need 110BCD.
I ride a bike. Doesn't make me green or a tree hugger. I drive a car too.
Your chain may need shortening too.
Red bikes are the fastest.
