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

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

Thanks to its progressive gearing, gear jumps are particularly small at high speeds and become larger in the easier gears - ideal for steep climbs and changing terrain.

A major advantage: The cassette fits a classic 11-speed HG freehub body, so 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: small gear jumps at speed, larger steps uphill.
• Gravel optimized: ideal for bikepacking and off-road rides.
