created the thread Crank arm seems to loosen after half hour or so of riding (FSA MegaExo Crank)
" It was installed a few weeks back and it seemed to be fine for first few weeks.
However, now I can feel some vibration (sort of like "clicks") when I pedal. If I tighten the crank with a hex key, it goes away until 20-30 minutes later, when it will start "clicking" again.
Can anyone tell me... "
