The SRAM Rival XG-1250 is a 12-speed road cassette for SRAM Rival AXS wireless drivetrains. X-RANGE gearing gives it a wide ratio spread for road and gravel — a light top-end for climbing without sacrificing a usable large cog. The XDR driver interface is required; this cassette won't fit a standard HG freehub.

Highlights

  • 12-speed road cassette for SRAM Rival AXS drivetrains
  • X-RANGE gearing — wide ratio spread for road and gravel terrain
  • Requires XDR driver freehub (road-specific XD format)
  • Compatible with SRAM Rival AXS rear derailleurs and shifters
  • Available in multiple ratio options

XDR driver

Road-specific Eagle-format cassettes use the XDR driver — an XD-compatible interface with an additional 1.85mm of width to accommodate road chainline standards. XDR is not the same as the MTB XD driver. Confirm your rear hub has an XDR driver before ordering.

Fit and compatibility

12-speed road cassette. Requires XDR driver freehub — not compatible with standard HG or MTB XD drivers. Compatible with SRAM Rival AXS and Red AXS 12-speed systems. Confirm ratio spread before ordering.
