Description
A countershaft sprocket is only as good as its durability and efficiency—and this SUPERSPROX 17-tooth unit delivers both in spades. Built from SCM-435 carbon-free steel and hardened to factory racing specifications, it resists wear and breakage far longer than standard sprockets while its ultra-hard surface layer cuts friction losses that rob you of power. Whether you’re hammering dirt tracks or pushing asphalt, this fully lightened, grooved-tooth design keeps your drivetrain sharp and responsive.
