I recently put on a cadence bike computer on my bike and the results are higher than I expected. I know the optimum cadence rage is 90-100 rpm, but I saw that I consistently spin between 110-120 rpm. When I do this, I don't feel uncomfortable and I don't feel as if I'm bouncing around in the saddle. I was wondering if there was any advantage to shifting to a larger gear and dropping my cadence down to the 90-100 range, or is cadence just like anything else in cycling..a personal preference?
