KMC X Flat Go Waxed 12/13 Speed Flattop Chain

The KMC X Flat Go Waxed 12/13 Speed Flattop Chain is engineered for riders who demand smooth performance and lasting efficiency. Pre-treated with KMC GO wax, this chain offers cleaner, quieter operation with reduced friction and wear — perfect for high-end road, gravel, and MTB setups.

Its unique flat-top profile allows for a narrower, lightweight design without compromising strength or shifting precision. Exclusively compatible with SRAM 12-/13-speed AXS or Transmission (T-Type) drivetrains, the X Flat Go ensures a precise fit and consistent power transfer across every pedal stroke.

Ideal for cyclists who value performance with minimal maintenance, the KMC X Flat Go combines cutting-edge chain geometry with advanced wax lubrication to deliver top-tier reliability and speed.

Enhanced with KMC’s exclusive GO Wax formula and specialized wax treatment, the chain offers superior pedaling efficiency and exceptional durability. Unlike traditional oil-lubricated chains, the wax coating repels dirt and grime, reducing maintenance needs and extending the lifespan of your drivetrain components.

This dry wax technology significantly lowers friction for smoother, faster shifting and improved power transfer. The durable microfilm created by the KMC GO Wax treatment resists water, dirt, and stickiness, providing a cleaner, longer-lasting chain compared to oil-based alternatives. When maintenance is needed, a simple application of KMC GO Wax quickly refreshes the protective layer for continued high performance.
