Description
If you’re running a 520 chain on your off-road machine, sprocket wear is inevitable—but premature failure isn’t. The Renthal TwinRing 51T combines a lightweight 7075 T-6 aluminum core with a durable electro-less nickel-coated steel ring, delivering three times the lifespan of standard aluminum sprockets without the weight penalty of all-steel alternatives. The self-cleaning mud grooves and permanent bonding process keep your drivetrain performing consistently, lap after lap.
