Friendly reminder: 1. Friends who like speed can choose to replace the small tooth sprocket without changing the crankset to achieve the purpose of increasing the gear ratio. Friends who play action can also change to a larger flywheel than the existing car, so that the control is more free and the force is more even. 2. The size of the tooth pattern of the flywheel is different from that of the fixing ring. Only the really dead hub can be installed (the side with 2 tooth patterns). Please confirm whether your hub is really a dead hub, the side that is mounted live cannot be fitted with a fixing ring. This type of flywheel is not suitable for coasting hubs.
