Massive range without the compatibility headache. The SRAM Apex XPLR CS-PG-1231-D1 12-speed 11-44T cassette delivers the 400% coverage of a double chainring in a streamlined 1x package, mounting directly to traditional HG 11-speed driver bodies. The intelligent cog architecture preserves tight steps for high-speed cadence control, while widening the gaps on the low end to help you spin up the steepest walls.
