2. The original pedal is a spherical pedal, which will make abnormal noise after entering the water.
Solution: A better pedal is not expensive, so you can buy it yourself and change it yourself.
3. Formula The normal sound disappears or is uneven after the quick release aluminum alloy disc brake hub is flooded, and there will be problems in the hub transmission when riding, which may be seriously locked.
