Thanks for the help guys. Just did a 25 mi ride today with the saddle lowered by 2 mm. The knee is much better. Don't feel much pain at all in the knee. I ordered a leg length kit from speedplay the other day. Should I raise the saddle back up to the original height and add the shim piece to my right cleat so that the right leg is equal with the left leg or just leave the saddle where it is now?
