The SRAM XPLR XG-1251 is a 12-speed gravel cassette in the XPLR drivetrain range — wide-range gearing with ratio spread optimised for gravel and mixed-terrain riding. Individual cog construction on an aluminium carrier reduces weight, and XDR road driver compatibility makes it the correct cassette for XPLR AXS and mechanical gravel builds.
