KMC XSL Flat Waxed Chain 12/13s 126L 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.

Super Light (SL) | To save even the last gram, the SL models feature not only perforated inner and outer flanges but also hollow rivets. However, this maximum weight reduction does not come at the expense of performance or shifting characteristics.

GO WAX | A noticeable reduction in friction and a significant improvement in shifting performance. GO WAX’s innovative dry wax formula makes this possible. The advanced KMC chain wax not only ensures optimal efficiency but also extends the drivetrain’s service life by forming a water repellent microfilm on the chain. This permanently prevents both heavy dirt buildup and accelerated chain wear.
