KMC XSL Flat Go Waxed 12/13 Speed Flattop Chain - Crimson Blaze

The KMC XSL Flat Go Waxed 12/13 Speed Flattop Chain - Crimson Blaze combines elite-level drivetrain performance with a bold, eye-catching finish designed to stand out from the crowd. Developed for riders who demand the lightest and most efficient components, this premium chain arrives pre-treated with KMC GO Wax technology to deliver exceptional pedalling efficiency, reduced friction, and a remarkably clean-running drivetrain.

Built using KMC's advanced XSL architecture, the chain features hollow pins and hollow inner plates to minimise weight while maintaining the strength required for high-performance riding. Its FlatTop profile is specifically engineered for SRAM 12- and 13-speed AXS and Transmission (T-Type) drivetrains, ensuring precise shifting, reliable chain retention, and optimal power transfer under load.

Unlike conventional lubricated chains, the KMC GO Wax treatment creates a dry protective layer that helps repel dirt, dust, and moisture. This reduces contamination build-up, keeps the drivetrain cleaner for longer, and contributes to smoother operation with less maintenance. The result is a quieter, more efficient drivetrain whether you're racing, training, or tackling long-distance adventures.

Finished in the distinctive Crimson Blaze colourway, this chain not only delivers race-ready performance but also adds a unique visual upgrade to any modern drivetrain setup.
