im actually in the same boat - brand new at track, raced "C" last week, gearing slightly low at 48/15t

im gonna get a 50t ring put on b4 TNR tonight. the officials want me to race "B" already so it should be fun racing in faster more competitive field for a few weeks


i can already see how there is certainly an optimization between having a big and low gear - the lower gear will make it easier to respond to surges and accelerations, but you will be missing out on some top end sprint.
