Hi bros
Recently I have been hearing the occasional clunk sound coming from my crankset. Today I got home and really tried to find the origin, I've noticed:
- it doesn't happen when the wheels are off the ground and I spin freely
- it only happens when pressing down on the left pedal/crank, then I hear a "clang". It's not every revolution but definitely a lot. It is easy to reproduce by standing still, then pressing down the left pedal.
See picture enclosed, imagine the black is my foot position before the clang and the blue position behind the clang. The sound would happen somewhere between that angle. It's a relatively new bike, 2500km, FSA crankset
