Description
Rear sprocket selection directly impacts your bike’s acceleration, top speed, and chain longevity—making durability and weight critical factors in performance. The Renthal Twinring 50T combines a lightweight 7075 T-6 aluminum core with a hardened steel outer ring, delivering three times the lifespan of conventional aluminum sprockets without the weight penalty of all-steel alternatives. Self-cleaning mud grooves and reinforced flat socket screws ensure consistent performance in demanding conditions while minimizing maintenance downtime.
