I have posted here before asking for bike fitting advice. I have then been to two bike fitters. None can solve my problem or even see the problem. Gradually, I found my problem is in the right upper leg and lower leg not aligned. When I bend my knee on one leg (holding the other), left knee and ankle is in a straight line, while the right not in a straight line, the knee tends to go inside of the ankle. If I stand with both legs straight, I can visually see the right knee a little bit to the left of the right lower leg. Not obvious but can be seen. My right leg can't put full strength on the pedal, always slips off (on flat) or twists (with clipless) because the misalignment. I have tried wedges, not much help. My right foot is in a extreme position (only right edge of the right foot can touch the pedal, so wedges are never enough). Strangely, that only affects cycling, I have no problem in walking, running, hiking. I began seriously cycling one year ago and hence noticed the problem. I am thinking if it's a muscle problem may it can be corrected by yoga or something, while if it's the bone problem I will probably give it up. Who should I go next? I think I need to have some x ray photo to reveal what's happening.
