Hey Bob, I've sourced 160mm cranks. I'll test these on the M510 vs 150mm cranks when the motor arrives.

Got me thinking that I know there has to be a limit to how short cranks can still be efficient at over the power band and think I might take my stock 170's and shorten them to 140's just to see? I have no other use for them.

I think that on technical descents, the shorter cranks will start to feel unstable, as the you're standing on a narrower platform

Moto guys do pretty well on pegs eh? I am more concerned with how they react with a torque sensor tuned to them and getting the most efficiency possible out of each revolution. Of course there are other factors in play especially gearing and mode selection vs. terrain.
