SRAM XPLR PG-1231 Cassette - 12-Speed, 11-44t, Silver, D1

The SRAM XPLR PG-1231 gravel cassette is built for riders running SRAM's 12-speed XPLR drivetrain who need extended climbing range on mixed terrain and loaded routes. The 11-44t spread covers both fast flat sections and steep, sustained climbs without requiring a mountain-spec cassette swap. D1 generation designation confirms compatibility with SRAM XPLR derailleurs and AXS XPLR shifters. Steel construction keeps the build durable across long gravel miles where cassette wear is a real factor.
