Designed for off-road competition, this RENTHAL Ultralight sprocket is machined from 7075 T6 aluminium, known for its excellent weight/stiffness ratio. Its specific tooth profile promotes mud evacuation and helps reduce friction between the chain and the sprocket, resulting in a cleaner performance on muddy terrains.
