SUPERSPROX Countershaft Sprocket - 17-Tooth CST-1579-17-2

A countershaft sprocket is your direct link between engine power and wheel traction—cheap out here, and you're risking premature wear, power loss, and catastrophic failure at the worst moment. The SUPERSPROX 17-Tooth CST-1579-17-2 is engineered with the same specifications trusted by factory racing teams, delivering the durability and precision needed to survive aggressive riding while maintaining efficiency across both off-road and street applications.

Built from SCM-435 carbon-free steel with a proprietary impregnation process, this sprocket eliminates the brittleness that causes teeth to shear under load. The ultra-hard surface layer reduces friction and chain drag, meaning more of your engine's power reaches the ground instead of being wasted through drivetrain resistance.
