KMC X Flat Waxed Chain

The KMC X Series chains are developed on decades of drivetrain R&D expertise, integrating advanced engineering and manufacturing innovations. Designed specifically for SRAM T-TYPE / Flattop 12/13 speed drivetrain systems, the X-Bridge structure features optimized chamfering and a widened inner bridge to ensure precise, stable shifting across a wide range of gear combinations and chainline conditions. This design enhances overall drivetrain compatibility while improving shifting efficiency and reliability. Combined with KMC’s GO innovative wax-based formula and a specialized wax treatment process, the chain delivers low-friction performance straight out of the box. This treatment significantly improves pedaling efficiency while doubling durability compared to conventional lubrication methods. Unlike oil-lubricated chains, wax-treated chains resist dirt and debris adhesion, reducing abrasive wear, simplifying maintenance, and extending the service life of both the chain and the entire drivetrain—ultimately lowering long-term maintenance costs.
