Don't worry TOO much about exact cadence numbers though. The ideal cadence varies for everyone. I'd try something between 80-110 and see what feels good to you. Some people are natural spinners and some are not. You can train yourself to spin higher cadences, but there is only one ideal power transfer cadence for your particular body.

MOST people are somewhere around 90-100. But it depends and you shouldn't kill yourself trying to stay in that range.
