Experience a lighter, faster-feeling drivetrain with the Renthal Ultralight Rear Sprocket. Precision CNC-machined from specially enhanced 7075-T6 aluminum, it’s engineered for riders who want reduced rotating mass while still demanding real off-road durability. The ultralight construction can be up to 66% lighter than steel, helping your bike respond quicker and feel more agile on track or trail.
