What to do when pedal started resisting to be attached to COGY
Have you experienced similar situation?
Even though the hexagon shape of crank side and pedal side is matched,
and even you press the black button on the pedal and press it hard towards crank,
pedal won’t go in.
Please look at the small ball on pedal axle.
and compare with the “after” video.
It seems because inner surface of crank side became rough.
Use sand paper to make it smooth.
Do you see,
now the pedal axle goes deeper than before,
bit more than the edge of silver colour ball on the axle.
