SRAM XG-1299 Cassette 12sp 10-52T Rainbow

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.

Featuring the industry’s strongest X-Dome™ architecture and proven XD™ driver body, it’s also backwards compatible to give riders even more Eagle™ upgrade options for their current bikes. With multiple Olympic, World Cup and World Championship titles, it also matches up perfectly to XX1 Eagle AXS™ enabled componentry. The XG-1299 cassette utilizes the full depth of the new Eagle™ Colour system.
