Chris King adds XD driver body for SRAM XX1

Retrofittable to existing hubs, works for XO1, too

Chris King today announced the release of a new XD driver body that enables the use of SRAM XX1 and XO1 cassettes on current ISO and ISO DH disc-compatible rear hubs. The new bodies will start shipping on May 1; pricing is yet to be announced.

Chris King will offer the new XD-compatible bodies in heat treated stainless steel only, although with a claimed weight of 331g for a complete 142x12mm hub, it adds just 6g over a standard ISO model with an aluminum driver. Even better, however, is that the new driver will retain Chris King's proven RingDrive freehub mechanism and can be retrofitted on to current ISO and ISO DH hubs as an aftermarket upgrade.

Chris King will offer complete XD-equipped hubs in nine colors and conversion kits will be available in multiple configurations depending on your DIY comfort level. The new hubs will also be sold as part of complete wheelsets.

Chris king will offer the new xd driver body as complete hubs, built into wheelsets, or as a retrofittable aftermarket upgrade:

James started as a roadie in 1990 with his high school team but switched to dirt in 1994 and has enjoyed both ever since. Anything that comes through his hands is bound to be taken apart, and those hands still sometimes smell like fork oil even though he retired from shop life in 2007. He prefers manual over automatic, fizzy over still, and the right way over the easy way.
  • Discipline: Mountain, road, cyclocross
  • Preferred Terrain: Up in the Colorado high-country where the singletrack is still single, the dirt is still brown, and the aspens are in full bloom. Also, those perfect stretches of pavement where the road snakes across the mountainside like an artist's paintbrush.
  • Beer of Choice: Mexican Coke
  • Location: Boulder, Colorado, USA
