I'm curious on this one, would you go longer or shorter when converting to a triple from a double? I mean crank arm length is dictated by your leg length. But when you goto a triple, your rpm (in theroy) can speed up which means a shorter length will get you the same amount of torque from the increased rpms. But, you typically goto a triple to make climbing walls easier which a longer crank arm will also help. Gimme some logic behind this madness... :mumble:
