This is me at 320 pounds, May 2006. Look at the right leg, if you dare. I can't clip in for any length of time on the right without knee pain. And since my right heel strikes the bike if I pedal properly, I often wind up pedaling with my arch or heel on the right. I know there's a product, Knee Savers, that will extend the crankarm so I don't have heel strike, but is there a clipless system that will allow me a considerable amount of float? I currently use spd multi-release pedals and cleats. An alternative might be to angle the cleat on the right side, but I don't see how to do it without boring more holes on the bottom of my shoe. Anyone have experience making such alterations?
Oh, and the right knock has moderated a little since there's 80 pounds less on it and the muscles are stronger. Still, with a leg like that if I were a horse I would have been put down long ago.
