SRAM XX1 Eagle XG-1299 12-Speed Cassette

Part of SRAM'S new XX1 Eagle™ drivetrain, built for cross-country performance, the XG-1299 12-Speed Cassette is light and strong. Comprised of a machined cromoly 11t cog cluster and an aluminium 50t cog, this cassette features X-DOME technology, designed to clear mud fast for cleaner and more precise shifting.

This cassette, and the Eagle XX1 drivetrain remove any doubts over the benefits of a 1x system on mountain bikes. With 12-speeds and a 10-50t range, a 500-percent gear range is offered at a significantly reduced weight. Shifting up and down the cassette is smooth and quiet while chain retention is improved so you can focus fully on your performance on the trails.
