I am trying to determine what adjustment I need to make to resolve the following issue. I seem fairly comfortable on rides, but I noticed that when I am coming back up with my right leg to the 12 o'clock position with the crank, my knee starts going outward towards 1 o'clock or 2 o'clock. My left leg seems fine. Is this a fore aft problem? Or a saddle height problem? Also, if I start going higher, my left leg seems like it is overstretching. At some point I need to get professionally fi, but cannot afford it right now.
