My commuter (on old Huffy) has an annoying click that happens with every revolution of my crank arms. It always happens when the right pedal is at the top of it's arc. It seems to be getting worse. What can I do to fix this? I want to do long distance bicycle touring so I would prefer to fix the problem myself rather than go to a LBS.
Please excuse me if this quuestion has already been asked and answered before. John
