KMC XSL Flat Go Waxed 12/13 Speed Flattop Chain

The KMC XSL Flat Go Waxed 12/13 Speed Flattop Chain takes the proven performance of the X series to the next level with a super lightweight construction and enhanced efficiency for competitive riders. Pre-treated with KMC GO Wax, this premium chain delivers ultra-smooth, quiet, and low-friction performance — ideal for high-end road, gravel, and MTB drivetrains.

Engineered with KMC’s XSL hollow-pin and inner-plate design, the chain reduces weight without sacrificing strength or precision. The distinctive flat-top profile enables a narrower chain while maintaining superior durability and shifting accuracy. Designed exclusively for SRAM 12-/13-speed AXS and Transmission (T-Type) systems, the XSL Flat Go ensures perfect engagement and consistent power delivery across every gear.

With its advanced dry wax technology, the XSL Flat Go repels dirt and moisture more effectively than oil-based lubricants, keeping your drivetrain cleaner and extending component life. The KMC GO Wax microfilm minimizes friction and resists buildup, ensuring faster, smoother shifts and long-lasting performance — even under demanding conditions.

Light, clean, and built for speed, the KMC XSL Flat Go Waxed Chain is the ultimate upgrade for serious cyclists who want the fastest, most efficient connection between power and performance.
