Features: Long-term use without inspection and adjustment will cause the chain to loosen. If the chain is too loose, it will cause jitter, chain jam or even drop during driving. If the chain is too tight, it will increase friction and component wear, or there may be abnormal transmission noise or even chain breakage faults, which will also cause excessive power consumption. Therefore, it is necessary to check and replace your chain adjuster regularly to ensure driving safety
