Description
A lighter rear sprocket directly translates to reduced unsprung weight, sharper acceleration, and improved handling—critical advantages whether you're racing or pushing hard on technical terrain. The Renthal 50-tooth aluminum sprocket replaces wear-prone steel with 7075-T6 aluminum that's 66% lighter while maintaining the durability needed for aggressive off-road riding. Self-cleaning tooth grooves eliminate mud accumulation that degrades performance, so you maintain consistent power transfer lap after lap.
