Renthal Twinring Rear Sprocket 50

The ultimate dirt bike rear sprocket for those looking to ride more and work less, its unique, dual-material design combines a hardened steel outer chain ring that is heated to 200°C before being permanently fitted to our Ultralight aluminium inner, creating a permanent bond for the life of the sprocket. The result is a lightweight, long-wearing rear sprocket fit to tackle any condition without adding unnecessary unsprung weight and compromising power delivery.
