Our XSL FLAT Flat-Top chains are specifically designed for modern SRAM 12/13-speed drivetrains and are characterized by their distinctive flat top profile. This design allows for a narrower chain while still providing high strength and durability. The XSL FLAT features hollow pins and drilled face plates to shed weight while maintaining unbeatable strength and performance. Flat-Top chains are exclusively compatible with SRAM's 12-/13-speed AXS drivetrains or Transmission/T-Type. They are not compatible with other 12-/13-speed systems or older SRAM groups. Thanks to the innovative formula of KMC GO CHAIN WAX, the premium KMC chains treated with our wax from the factory offer high efficiency and unrivaled durability. Compared to oil-based lubricants, waxed chains are less susceptible to dirt build-up — making them a low maintenance choice that increases drivetrain life and reduces cleaning intervals. Don't spend extra time waxing your new chain at home, buy a KMC pre-waxed chain, skip the mess, and go ride your bike!
