Description
Sprocket wear is one of the fastest paths to drivetrain failure, especially under racing conditions or aggressive riding. The Renthal TwinRing 51T combines a lightweight 7075 T-6 aluminum core with a durable nickel-coated steel outer ring to give you three times the lifespan of standard aluminum sprockets—without the weight penalty of going full steel. The self-cleaning mud grooves mean less downtime cleaning drivetrain buildup and more time maximizing performance.
