SRAM XX1 Eagle XG-1299 12-Speed MTB Cassette 10-52T Gold — X-DOME, XD Driver, 520% Range

The SRAM XX1 Eagle XG-1299 is the flagship of the Eagle drivetrain, and this 10-52T version stretches the spread to a full 520% — enough to clear pitches that would stall a 10-50T setup. Eleven cogs are machined from a single piece of chromoly steel using SRAM's X-DOME architecture and capped with an aluminum 52T finishing cog, while X-GLIDE 2 tooth profiling keeps shifts crisp under power. The gold anodized finish matches SRAM's Gold XX1 Eagle chains and chainrings.
