SUPERSPROX Countershaft Sprocket - 18-Tooth CST-1180-18-2

If you're running a countershaft sprocket that's holding back your power delivery, you're leaving performance on the table. The SUPERSPROX 18-tooth countershaft sprocket eliminates the friction and durability concerns that plague standard sprockets, delivering the same factory-spec reliability trusted by professional racing teams. Built from SCM-435 carbon-free steel with a hardened surface layer, this part is engineered to survive high-load conditions while maintaining precise chain engagement lap after lap.

Whether you're competing off-road or pushing hard on the street, the grooved teeth design sheds dirt and debris instantly, while the radial lightening holes reduce unsprung mass without compromising structural integrity. This is genuine factory team equipment, not a compromise part.
