SRAM XX1 Eagle 10-52 Cassette Gold

Whether for prized race machines or the build of their dreams, the XG-1299 cassette is the ultimate, giving riders unprecedented 520-percent range thanks to the new 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.
