SUPERSPROX Countershaft Sprocket - 15-Tooth CST-4041-15-2

A countershaft sprocket is only as strong as its material composition and surface treatment—and this is where SUPERSPROX separates itself from the competition. The CST-4041-15-2 is engineered with SCM-435 carbon-free steel and a proprietary impregnation process that eliminates the weak points found in standard sprockets, giving you the durability and consistency that factory racing teams demand. The ultra-hard surface layer reduces friction-induced power loss, while the radial lightening holes and grooved tooth design keep you competitive whether you're on asphalt or dirt.
