12-speed cassette with a wide range for gravel and road 1x drivetrains.

The SRAM Apex PG-1231 XPLR Cassette offers an impressive 400% gear range, combining the advantages of a 2x drivetrain in a simple 1x setup. Perfect for gravel, bikepacking, and demanding road use.

Thanks to its progressive gearing, the gear steps are particularly fine at high speeds and become larger in the easier gears – ideal for steep climbs and varied terrain.

A major advantage: The cassette fits on a classic 11-speed HG freehub body, meaning no special freehub is required.

Highlights:

• 400% Range: covers fast road sections and steep climbs.
• 1x Setup: simple, low-maintenance shifting without a front derailleur.
• Shimano HG Freehub Compatible: compatible with standard cassette mounts.
• Progressive Gearing: fine gears for speed, large steps uphill.
• Gravel Optimized: ideal for bikepacking and off-road rides.
