Designed to run up to 20 degrees cooler; proven in washout comparative testing. Engineered with deeper cogs and increased flexibility reducing rigidity while increasing cooling. Manufactured in Japan with high-end rubber components that reduce heat build-up and reduce failure. Rubber compound constructed from high-strength aramid cords and fibers to increase grip. Cut Taper manufacturing process creates a more consistent edge with fewer loose cord fibers vs Ground Taper. Belt performance matches and exceeds OEM.
