This is because the old parts are worn out during long-term use, and when the new parts are used in combination, the wear of the teeth makes it impossible to effectively engage. Generally, in such a situation, you only need to continue to run for tens of kilometers, and the problem will automatically disappear. If your chain has been used for more than 3,000 kilometers, it is recommended to change the chain at the same time as you change the flywheel.★Quality Service:- We are committed to bringing the latest and most innovative high-quality bicycle accessories to the market.
