The KMC X Flat 12-Speed Chain (126 links) is engineered for maximum strength, smooth shifting, and long-lasting performance on modern SRAM 12-speed AXS and 13-speed Transmission drivetrains. Featuring SRAM’s innovative Flat-Top chain design, this chain delivers a narrower profile without sacrificing durability, making it perfect for road, gravel, and MTB riders who demand precision and reliability.
With a nickel-plated silver finish for added corrosion resistance and pre-waxed with KMC GO lubrication, the X Flat 12-Speed chain ensures smooth pedalling efficiency and reduced drivetrain wear. The included KMC MissingLink makes installation and maintenance quick and easy.
Compatibility Note: Designed exclusively for SRAM Flat-Top drivetrains (12-speed AXS or T-Type/Transmission). Not compatible with standard 12-speed chains or older SRAM systems.
