SRAM XG-1299 Eagle Cassette - 12-Speed, 10-52t, For XD Driver, Rainbow, C1

Whether building the bike of your dreams or preparing for race season, the SRAM XG-1299 Eagle cassette delivers a 520% gear range that empowers stronger riders to choose larger chainrings for top-end speed without sacrificing climbing ability. The X-Dome architecture—a hollow, CNC-machined single steel block—creates a lightweight, stiff drivetrain component with excellent mud clearance and precise shifting. More time spent in the upper cassette range means peak power transfer efficiency and reduced wear. The proven XD driver body is backwards compatible, unlocking additional Eagle upgrade options for your current bike.
