During the shifting process, these impurities may interfere with the normal operation of the transmission, causing abnormal noise. In order to solve this problem, the transmission can be cleaned regularly and special cleaning agents can be used to remove oil stains and impurities. At the same time, keeping the transmission dry to prevent moisture from entering can also effectively reduce the occurrence of abnormal noise.
Secondly, worn or damaged parts inside the transmission may also be the source of abnormal noise. For example, wear or damage to parts such as chains, gears, and derailleur paddles may cause abnormal noise during shifting. In this case, it is necessary to check the wear of these parts and replace the severely worn parts in time. In addition, regular maintenance of the bicycle and timely replacement of worn parts can also effectively prevent the occurrence of abnormal noise.
In addition, the installation and adjustment of the transmission may also affect its normal operation. If the transmission is improperly installed or adjusted incorrectly, it may cause increased friction between the chain and gears, resulting in abnormal noise.
