KMC X-FLAT Waxed Flat-Top chains are specifically designed for modern SRAM 12/13-speed AXS or Transmission/T-Type drivetrains and are characterized by their distinctive flat top profile. This design allows for a narrower chain while still providing high strength and durability. Thanks to the innovative formula of KMC GO CHAIN WAX, these premium KMC chains treated with their wax from the factory offer high efficiency and unrivaled durability. Compared to oil-based lubricants, waxed chains are less susceptible to dirt build-up - increasing drivetrain life and reducing cleaning intervals.
