Renthal TwinRing Rear Sprocket 50T Black 1120-520-50GPBK

If you're running a 50-tooth rear sprocket on your dirt bike, you need a component that can handle both the demands of aggressive riding and the punishment of off-road terrain. The Renthal TwinRing combines a lightweight aluminum core with a hardened steel outer ring—delivering the durability of a steel sprocket without the weight penalty. You'll get three times the lifespan of standard aluminum sprockets while maintaining the responsiveness your bike needs.

The TwinRing's dual-ring construction uses a permanent thermal bond, eliminating any risk of ring separation under load. Self-cleaning mud grooves between each tooth prevent debris buildup, which means less wear and more consistent chain engagement when conditions get messy. For riders who demand reliability without compromise, this is the sprocket that delivers.
