I recently went clipless with SPD on my hybrid and I'm delighted with the pedals, so easy to use and so more efficient than flats! I'd like some advices on how to best adjust the cleat position on the shoes. The forward/backward setting has quite a wide range, I tried different positions and found that I'm pushing with a different part of the foot each time. So what is better? I mean what part of the foot should push on the pedal to be the most efficient? I know you will tell me to use the most comfortable position but the problem is I find all positions comfortable... just different. Obviously I had to adjust the saddle height up when pushing with the front of the foot. So what is generally recommended? Thanks!
