I've got a lot of experience using levers, and I always like to use the longest lever I can that will fit within the confines of the job needing doing. Sounds like you need a shorter lever to stay within the confines of the job you need doing, but it'll cost you leverage. Sheldon uses crank arm length in his gear range calculator, so It must be a factor! (however insignificant, depends on your choice of cranks. His calculator goes down to 100mm, that seems too short) Worse case is it expands your LCG? -Kai BK NY
