Description
Countershaft sprockets endure extreme stress during acceleration and deceleration—a weak link here means power loss, premature wear, and potential catastrophic failure. The SUPERSPROX CST-423-18-2 is engineered with the same specifications trusted by factory racing teams, delivering the durability and efficiency required for both competitive racing and demanding street use. Its advanced material science and lightweight design eliminate friction-induced power loss while maintaining zero-compromise reliability under sustained load.
