The KMC X Flat 12-Speed Chain is a high-strength chain built for SRAM 12 and 13-speed flat-top drivetrains. Its flat-top profile creates a narrower shape without reducing durability, helping deliver smooth shifting, efficient power transfer, and reliable performance under load. The chain comes waxed with KMC GO to reduce friction from the first ride, while the nickel-plated finish improves resistance to wear and corrosion in wet and muddy conditions. A reusable MissingLink also makes installation and maintenance faster and simpler.Key Features and Benefits:Flat-top chain design: The flat-top profile is designed specifically for SRAM AXS and T-Type drivetrains. This shape allows the chain to run narrower while maintaining high tensile strength and structural rigidity. The result is precise shifting, stable drivetrain performance, and dependable durability across demanding riding conditions.KMC GO wax coating: The factory-applied wax coating reduces friction between the chain, cassette, and chainring from the start. Lower friction helps improve drivetrain efficiency and reduces premature wear on key components. This leads to quieter running, smoother pedalling, and lower long-term maintenance costs.Nickel-plated silver finish: The nickel-plated coating helps protect the chain against corrosion, dirt, and moisture exposure. This improves durability in mixed weather and trail conditions while helping the chain retain smooth movement over time. The outcome is more consistent performance and less risk of rust-related wear.Missing Link connector included: The supplied Missing Link allows quick chain installation and removal without specialist tools. This makes cleaning, maintenance, and replacement work faster and easier. The benefit is reduced workshop time and simpler drivetrain upkeep for regular riding.Reliable shifting and drivetrain efficiency matter most when using modern 12 and 13-speed systems. The KMC X Flat 12-Speed Chain is designed to match the tight tolerances of SRAM flat-top drivetrains, helping maintain accurate gear changes under power. Its waxed finish supports smoother chain movement, while the reinforced flat-top construction helps handle the higher loads created by modern drivetrains and e-bike compatible systems. The 126-link length also gives added flexibility for a wide range of bike setups.The KMC X Flat 12-Speed Chain combines drivetrain compatibility, low-friction performance, and long-term durability in one dependable package. Its flat-top design and waxed finish make it a strong option for riders who want smooth shifting and lower drivetrain wear from every ride.Specification:Compatible with all SRAM 12-/13-speed derailleur systems using flat-top chainsWaxed with KMC GOIncludes a Missing LinkDurability: ***Size: 1/2" X 11/128"Colour: Nickel plated SilverLength: 126 links
