Note: This model comes with a magic buckle, easy to install and easy to remove, no extra price, PPO ending, tension: 950KN I am not afraid of comparison shopping but I am afraid of not knowing the goods.

[ Precautions]
Before replacing the chain, please be sure to confirm the length. Cut as many sections as the length requires and cut to the appropriate length before installing. In addition, check the wear of the flywheel of your car. If the flywheel is severely worn, it is recommended to replace it together with the chain. If the flywheel is not replaced, , the new chain and the old flywheel may not match, and the chain may jump or become empty during riding.
After the new chain is installed, the rear derailleur must be re-adjusted. If chain skipping occurs, please do not suspect that there is a problem with the chain. The probability of a problem with the new chain is almost 0. It is time to debug the rear derailleur and check the flywheel gear wear. The degree of wear is light, just break it in after riding for a while. If the wear is serious, just replace the flywheel with a new one. Please inform me.!
