I've been playing around with this knee over pedal thing for quite a while now and I can't seem to get it. I've read Peter White's overview on the subject and I've read Andy Pruitt's as well. Peter says it doesn't make any difference, and Andy says it does. Is it just a starting point and when you find your comfort zone, just stay there? If it's that you need your knee cap over the end off the end of the crankarm I'll have to buy a setback seatpost. It just seems to me, if I can go a pretty good distance, should I change anything or not. I was looking at the point of the power output you can put out with your knee as far back as you can get it as well. Thanks for any replys.
