SRAM XG-1299 XX1 Eagle Cassette (Copper) (12 Speed) (XD) (10-52T)

Whether for prized race machines or the build of their dreams, the XG-1299 12-Speed cassette is the ultimate, giving riders unprecedented 500%/520% range thanks to the 10-50/10-52 tooth-span. Stronger racers are now free to choose larger chainrings for more top-end speed, without sacrificing climbing range. More time is spent higher up in the cassette where athletes’ power transfer is most efficient and wear is minimized.
