Sram Xplr PG1231 D1 Cassette

Maximum Range. Minimum Fuss.

This 12-speed 11–44T cassette delivers the gear range of a traditional 2x drivetrain in a simple, lightweight 1x setup. Compatible with standard 11-speed freehub bodies, it offers broad compatibility without the need for a dedicated driver.

A carefully optimised cog progression keeps gear steps tight where speed matters most, while providing more effective jumps for efficient climbing. The result is smooth, intuitive shifting and the versatility to tackle everything from fast flats to steep ascents.
