What's the optimum ratio for preventing knee injury whilst still maintaining a decent average speed.

big gears are fine as long as you can actually pedal them.if you are reving them at 80+ most of the time,it shouldn't be a problem.however if you are doing 20 revs a minute and nearly bending the cranks to do it your knees are going to hurt.
