is there any benefits to one gear ratio over another?

commute to work is about 12 km – although i double that a couple of times a week.

recently changed from 70″ fixed, to 63″ free & back to 70″ free.

ignoring the fixed/ free debate i have seen my cadence go up & back down with the gear changes but i’m certainly no faster & possibly slower with the bigger gear. the lower gear feels like a better rhythm; but seems generally low compared to what others run.

It’s a personal thing. What’s a good gear for you is not necessarily a good gear for someone else and vice versa.

If 70″ feels too big and 63″ feels right forget about everyone else…

I choose a gear in which I can maintain a smooth spin – one that’s neither straining to get over teh gear nor one that’s outspinning it.
