SUMC E-Bike 11/12-Speed Chain

The SUMC E-Bike 11/12-Speed Chain is built with ultra-precise manufacturing, keeping tolerances within 1μm for flawless drivetrain performance. Designed specifically for mid-to-high torque e-bike systems, it delivers unmatched strength and reliability even in rugged conditions.

With a tensile strength exceeding 1060kgf and advanced hardened-steel pin treatment, the chain offers more than 2x the wear resistance of standard models. Its mushroom-riveted pins withstand over 460kgf, ensuring secure performance on tough mountain trails and in extreme environments.

The double X-shaped construction with chamfered inner and outer plates guarantees smooth, fast, and accurate shifting across the cassette. Finished with a Ti-Nitride coating for reduced friction and extended lifespan, the SUMC E-Bike chain is also fully compatible with Shimano, SRAM, Campagnolo, and Bosch 12-speed e-bike systems.
