maybe time to mute the moot point. Or was the statement pointless and the finger speechless? E.E. Cummings
I will say this: back when I was road racing, I did a lot of high cadence training -- mostly because I had a weak sprint and needed to improve it. Learning to spin smoothly at 115-120 rpm is beneficial -- not just in a sprint, but when bridging up to a group, closing a gap after railing around a corner, etc. It's worth doing, if you're planning to race or just want to keep up on a fast group ride.
Beyond that, anyone who recalls watching Lance Armstrong and Jan Ullrich riding side-by-side will easily recognize that difference cyclists ride well at very different cadences, in normal circumstances.
