The SRAM Eagle XG-1299 12-speed Cassette features a 50T - 10T spread for a 500% gear range. This incredibly versatile cassette uses SRAM's X-Dome construction, with the first 11 cogs being machined from a solid block of chromoly steel for excellent durability, mud tolerance, and a low weight. The alloy 50-tooth cog is then pinned to the main body, and they all feature X-Glide 2 cog profiles to improve chain retention and shifting, as well as providing smoother and quieter operation.
Ti-nitride PVD coated main body. Compatible with hubs using SRAM XD freehub bodies. Claimed weight is 355 g. Cog sizes are 10-12-14-16-18-21-24-28-32-36-42-50.

Amazing cassette with amazing range
Recently bought a Jones Plus LWB and decided to try a 1x system. The SRAM Eagle seemed like the way to go. These cassettes are pretty amazing as, aside from the last 50t cog, it is machined from a single piece of metal. For the size of the damn thing the weight isn't bad. The range is great with a 10t small cog and 50t large, my only complaint is that in the sweet spot, for me with a 34t front ring, the % difference between gears is not as finessed as my road double. And, coming from DuraAce DI2, shifting is a little clunky. That is not to say the Eagle system works poorly, just kind of chunky shifting. I would not attribute that to the cassette, but more likely the extra long arm derailleur.
