ROSE Bikes E-bike Chainwheel for Bosch Gen 2| Chainrings|Drive Unit

KMC sprocket for Bosch drivetrains are specially designed for use on e-bikes. With e-bikes, chain, chainring and pinions transfer the high driving forces on the rear wheel and are therefore subjected to high stress and excessive wear. The higher weight of bikes with electric assistance also contributes to this. Even with good maintenance of all components, they need to be replaced after a certain period of time.
