Description
Countershaft sprockets endure extreme stress and chain drag that drain power and shorten component lifespan—especially in demanding off-road and racing conditions. The SUPERSPROX 15-tooth countershaft sprocket eliminates these performance killers with factory-spec engineering designed for real race teams, delivering measurable gains in durability, efficiency, and reliability. If you’re serious about maximizing drivetrain longevity and minimizing friction losses, this is the upgrade your bike deserves.
