SRAM XX1 Eagle XG-1299 12-Speed MTB Cassette 10-50T Rainbow — X-DOME, XD Driver, 500% Range

The SRAM XX1 Eagle XG-1299 is the flagship of the Eagle drivetrain — a 10-50T, 12-speed cassette machined from a single steel billet using SRAM's X-DOME architecture, with an aluminum 50T cog to keep weight at just 355 grams. The head-turning Rainbow finish matches SRAM's Rainbow/oil-slick XX1 components, and the open X-DOME structure sheds mud while delivering race-precise shifts.
