The KMC X Flat Chain is engineered specifically for modern SRAM 12- and 13-speed drivetrains that use “flat-top” chains. Its slim profile and precision-engineered construction deliver fast, smooth, and ultra-reliable shifting — ideal for road, gravel, MTB or cyclocross setups. Pretreated with KMC’s GO WAX at the factory, this chain runs cleaner, quieter, and more efficiently than standard oil-lubed alternatives. The wax finish repels dirt and water, reducing drivetrain wear and cutting maintenance intervals. With 126 links, 1/2″ x 11/128″ dimensions, and robust nickel-plated (or Ti-N coated) plates, it offers long service life and corrosion resistance ride after ride.

Key Features:

  • Flat-Top design — Narrow, SRAM-specific chain profile for 12/13-speed AXS / Transmission drivetrains.

  • Pre-waxed with GO WAX — Comes ready to ride — no messy chain waxing or prep required. The dry wax layer reduces friction, repels dirt and water, and extends drivetrain longevity.

  • Quiet, smooth shifting — Inner/outer chamfering and ramped plates deliver fast, precise gear engagement under load.

  • Durable materials & corrosion protection — Nickel-plated (or optional Ti-N coating) for enhanced hardness, rust resistance, and long-term performance.

  • Universal 12/13-speed compatibility — Ideal for road, gravel, MTB or cyclocross bikes running SRAM’s flat-top drivetrains.
