Its funny watching my powertap bounce when using the powercranks. The torque of my two legs legs must really be off because the numbers are not steady. I have decided that I need to adjust my cleats to allow for my new motion. I think that before my legs were not doing as much"efficient" work and my cleat position was less obviously wrong. I know cna feel that by moving my cleat I can enjoy more leverage from 6 oclock to 1:00. Good stuff.
