Anyway, there is an interesting discussion on the impact of crank length on cadence and torque in the Track forum:

My shorter cranks are the result of a fit. It was crazy how much better I felt moving from 172.5 to 165 on my road bike. I wasn't constantly fighting to get my knee/leg out of the way over the top of the pedal stroke. This isn't exactly the way it worked out, but imagine going from a dead spot from 9 to 2 on the clock to 11 to 1. Obviously you're not pulling up much on the upstroke, but instead of my hip/knee shifting out at 9 o'clock, they stay in track and I can get back on the power at 1 o'clock instead of 2.
