CMC

KMC is the world’s most widely used bicycle chain brand — a claim backed by Olympic gold medals, Tour de France KOM wins, and a manufacturing footprint spanning 11 plants across five countries. Founded in Taiwan in 1977, KMC pioneered lightweight chains, titanium-coated chains, and the DLC (Diamond-Like Carbon) coating technology that has since become the performance standard across professional cycling.

The RA Cycles KMC collection covers three core lines. The DLC Series sits at the top — a Diamond-Like Carbon coating reduces friction, extends chain life, and cuts maintenance intervals whether you’re chasing a PR or grinding training miles. The X Series adds color options including the Aurora Oil Slick finish, and the dedicated E Series chains are engineered specifically for the higher torque loads of e-bike motors. 21 options spanning 10-, 11-, and 12-speed compatibility.
