Twelve Smooth Steps

What could you possibly want from a gravel cassette? Lightweight, big range, and clean shifting. The SRAM XG-1251 XPLR 10-44 12-Speed Cassette does this, and more.

The 440% range of the XPLR 10-44T cassette provides smooth gear progression when you're sweating up gravel climbs, and tight jumps on the high end for when it's time to drill it on asphalt.

Shift features on each cog are optimized for electronic shifting, so you'll get fast, smooth, and precise shifts every time.

Weighing only 412g the XG-1251 model is the second lightest cassette in the XPLR lineup. Nevertheless, it is still significantly lighter than its competitors while offering more range. Weight savings in rotating areas of the bicycle significantly increase its overall efficiency.


  • X-Range gearing gives you more range and a smoother gear progression, so you're always in the right gear
  • 440% range gives the coverage 1x gravel riders want
  • For use with XPLR 1x rear derailleurs
  • SRAM 12-speed cassette
  • Compatible with Flattop chains
  • Compatible with XDR driver body
  • Mini Cluster technology for lightweight and durability

Smooth, fast, simple. But not lightweight...
by jakecalderburby
Competitive Racer

So far a fantastic piece of kit, perfect for my cyclocross/gravel build and combined with Red and Sram Force AXS xplr. While it's 10-44 cassette range is great for nearly every condition, it's not light, and I probably could have saved some weight going with a slight smaller range for cyclocross and road use, but the 44t does allow the use of the standard Sram AXS XPLR rear derailure rather than adding in anythign from the Sram MTB line for a "mullet build." The finish and weight of the Force is worth the extra over the rival, but as of yet, Sram does not have a Red XPLR cassette, hopefully on the schedule from sram if it will shave some weight.

Best value AXS cassette
by Anonymous
Cycling Enthusiast

I have a couple of the original Force AXS 12 speed cassettes and I actually like the Rival better. It may be heavier, but it shifts smoothly and crisply and, in my opinion is much quieter than the Force cassettes I have. In fairness, those cassettes are a couple of years old and Sram may have engineered them better by now. In any case, I don't see a reason to spend more money on something that does the same job. Weigh difference per dollar paid for Force or Red does not make sense to me.

Good Value vs Force Cassette
by trailrunz
Cycling Enthusiast

Works great and I feel like it is a great value compared to the very few grams you save upgrading to Force.
