Ranging from 10- to 42-tooth, the 11-speed X-Dome delivers an incredibly wide gear range while maintaining even, optimized steps. The single-unit cassette combines with the XD™ Driver Body for a superior connection to the wheel.


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.

XD Driver Body - XD is a new cassette driver body design that allows the use of a 10 tooth small cog and provides an improved interface with the cassette.


This XG-1199 X-Dome cassette is an integral part of the SRAM 1x drivetrain system. No comprimises.

Tested: Ten Months On SRAM XX1

"In conclusion, it’s still the same old drivetrain system we have had since the late 1800s, but XX1 is its biggest evolutionary step forward in a long time.

In short, I would find it hard to go back to anything else now.” View Article
