SRAM Officially Unveils XO DH
After teasing the market for a while, it’s official. SRAM is now offering a DH specific XO group. Many of the components that have been put through the rigors of the pro downhill circuit as Blackbox components, are now available to the public. The DH XO group is not replacing the standard XO, but adding to the versatility of the group.
Not only does this mark SRAM’s first DH specific rear derailleur, but also their first carbon DH race crank as well. Through the combination of the sub-800g carbon crank and short cage cassette, SRAM claims the XO DH group reaches a new level of stiffness and shifting reliability even under the toughest conditions.

Fortunately for SRAM’s development of XO DH, they have quite the list of sponsored athletes willing to dish out as much punishment as the parts can take. Development of the XO DH group has been ongoing for a while, with Peaty first winning on a prototype 10 speed XO group in 2009. Since then, much more development has passed, resulting in the polished group you see here.

Avid X0 Brakes
Interestingly, the XO brakes didn’t receive the same treatment to the lever that the new Elixir 7, 9, XX, and XXWC all saw. They do get the new HS1 rotor, but the brakes themselves don’t seem all that different save for an apparently new lever blade.
