The KMC XSL FlatW is a pre-waxed flattop chain made specifically for SRAM 12 and 13 speed AXS, Transmission and T-Type drivetrains. Choose Silver/Black, or the Aurora Blue and Gold versions in a limited edition box.

SRAM flattop drivetrains need a flattop chain, and a regular 12 speed chain will not do. If you run SRAM AXS or Transmission, this chain gives you a correct replacement that also runs cleaner and lasts longer thanks to its wax treatment.

Built for SRAM flattop systems

The flattop plate design matches SRAM’s flattop chain profile and tight sprocket spacing, giving accurate, stable shifting across the range.

Pre-waxed with KMC GO

The chain is factory-treated with KMC GO wax for low friction out of the box. KMC says the wax treatment doubles chain life compared to conventional lubrication.

Stays cleaner for longer

Waxed chains resist dirt and debris far better than oiled chains, which reduces wear on the whole drivetrain and makes maintenance simpler.

Strong and light

Hollow, extra stretch proof pins and KMC’s Double X inner bridge shape keep the chain light and rigid, with excellent pin strength.

Frequently Asked Questions

No. This chain is for SRAM 12 and 13 speed systems that use flattop chains. It is not compatible with other 12 or 13 speed systems or older SRAM groupsets.

Is a connecting link included?
Yes, it comes with a KMC MissingLink for tool-free fitting.

What is the difference between the colours?
Silver/Black is the standard version. Aurora Blue and Gold come in a limited edition box with a striking finish.
