I'm just getting back into riding after decades off the bike. I've adjusted my bike fit to my current shape and flexibility. It's been comfortable so far. However, the last couple of rides have had my right hip wanting to keep contracting at the top of the pedal stroke. This has been continuing eve off the bike, when I am sitting at the dinner table, any time my hip to upper body angle seems to be less than 90 degrees. Does anyone have any suggestions?
