I agree that riding at a higher cadence is learned. At first it does not feel natural. FWIW - I find that I can produce more power (and in my case more is an extremely relative term
) at 94 - 96 rpms on the flats riding solo and my legs fare better if I keep my climbing cadence at least at 80-85 rpm. Getting a compact has helped in the latter category. Finally, I find that the higher cadence is easier on my knees.
