Description
A worn or undersized countershaft sprocket will bleed power through chain drag and compromise acceleration across the entire RPM range. The SUPERSPROX 13-tooth CST-427-13-1 delivers the durability and efficiency demanded by factory racing teams, engineered with advanced steel metallurgy and a friction-reducing surface treatment that keeps your drivetrain responsive and reliable whether you’re pushing on the track or tackling technical terrain.
Built to the same specification as parts running in professional competition, this sprocket won’t let you down when it matters most.
