Looking for a real upgrade that actually delivers? The Renthal Ultralight Rear Sprocket (50T) is a game-changer for mini racers and serious riders alike. Precision CNC machined in Manchester, UK from aerospace-grade 7075 T6 aluminum, this sprocket is 66% lighter than steel, giving your bike better acceleration, less unsprung weight, and faster response off the line.
