Renthal TwinRing Rear Sprocket 50T Blue 1500-520-50GPBU

If you're running a 520 chain setup and need a sprocket that won't sacrifice strength for weight, the Renthal TwinRing 50T delivers the durability of steel with the lightweight advantage of aerospace-grade aluminum. The hybrid construction—combined with self-cleaning grooves and permanent thermal bonding—keeps your drivetrain efficient whether you're tackling technical terrain or pushing hard on the track. Built to handle impact loads and mud without premature wear, this is the kind of sprocket that pays for itself through reliability.
