Can someone help me troubleshoot this?
Whenever i pedal (apply more force, eg climbing hills), there seems to be an intermittent noise coming from the crank/bottom bracket area. Sounds like bird chirping noises, with a light grinding sound and a "clack" sound whenever the crank makes a full rotation. The 'clack" sound always happens at the same spot when i pedal.
Is this due to my bb? Is it busted already? Or is it due to crank? As when i cycle and look down, i can actually see my crank wobble a little. Have already tighten the crank bolt. However, when the bike is stationary, i realised that there is actually some play in the crank (lateral movement).
