The FSA chain guard ring is made of lightweight aluminium and is designed for e-bikes with Bosch Gen.4 drive. The chain guard protects against dirt and impurities on the chainring, as well as the rider’s trouser leg. A bead-blasted, black anodised finish completes the FSA chain guard ring so that it fits perfectly on the MTB. In addition to the chain guard ring, the scope of delivery also includes screws and nuts. As matching spacers, we also recommend the 4 mm Yamaha chain guard ring spacers.
