Renthal TwinRing Rear Sprocket 50T Black 1500-520-50GPBK

If you're running a demanding off-road program, your rear sprocket takes a beating—mud, impacts, and constant chain stress test durability limits fast. The Renthal TwinRing 50T combines a lightweight aluminum core with a hardened steel outer ring, delivering three times the lifespan of all-aluminum alternatives while staying lighter than all-steel options. That's the engineering advantage you need when every race weekend counts.

The dual-material construction isn't just about strength. Self-cleaning mud grooves between teeth prevent dirt accumulation that causes premature wear, while flat socket head screws resist side-load damage and eliminate chain guide interference. This sprocket is engineered to perform consistently across extended seasons without compromise.
