They are going to start a study, or are talking about starting one, on the position of the clips on your shoes. I was wondering if any of you have moved yours around to see if you can get more power out of having the clips under the ball of your foot, or all the way back as far as they would go. I had my back as far as they would go and they do feel good, but I just moved them to center just to try it out. I have better knee over pedal with the clips in the mid section closer to the ball of the foot and now my knee cap looks like it will be even with the end of the crank arm. I played with the handlebars and saddle and I'm pretty sure I'm where I have to be, but I thought if I could get a little more power to the crank it would help a lot as well. Thanks for any replys.
