Whether for the build of their dreams or getting the bike ready for the next race season, the XG-1299 cassette gives riders a 520% range and a unique finish. 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 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.
