Description
A lightweight rear sprocket is essential for competitive performance on the track or trail—it directly reduces unsprung weight, improves throttle response, and extends chain life. The Renthal 50-tooth sprocket delivers all three benefits with CNC-machined 7075-T6 aluminum construction that’s 66% lighter than steel while maintaining the durability demanded by serious riders. Its advanced tooth profile and self-cleaning mud grooves ensure consistent power delivery and reliable performance, whether you’re racing or pushing hard on technical terrain.
