The Centerpiece of the XX1 Eagle Drivetrain
The SRAM X-DOME™ Eagle™ XG-1299 cassette has no peer. Its 10-50 and 10-52 tooth gear range has opened the door for an entire ecosystem of Eagle™ groupsets. Designed for use with SRAM's proven, reliable XD™ driver body, this 12-speed, cassette offers an optimal 500-520% gear range.
X-Dome technology creates an incredibly lightweight, precise, and strong cassette. The Open design aids in mud clearance, giving you cleaner shifting performance and longer component life.
In independent tests the X-Dome™ architecture has proven to yield the strongest cassette on the market. New shifting characteristics improve both inboard and outboard shifting, as well as chain retention. This cassette matches up perfectly in performance and color to XX1 Eagle AXS™ enabled componentry.

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.
