Why We Like The Rival XPLR XG-1251 12-Speed Cassette

With X-range gearing and a 440% range, the Rival XPLR XG-1251 12-Speed Cassette ensures we're always in the right gear and with the amount of coverage we're looking for with a 1x gravel bike. This cassette lets us spice up our ride with a little dirt, a little gravel, and a whole lot more fun. Shift features on each cog are optimized for electronic shifting so we get smooth, quick, and precise shifting no matter what.


  • Smooth gear progression from this gravel-focused cassette
  • 440% range for coverage we want with a 1x gravel grinder
  • X-Range gearing gives us more range and the right gear, always
  • XDR driver body for a lighter and more versatile drivetrain
