SRAM X0 Mountain Group

The 2016 SRAM X0 Mountain Group is a high-end multi-use off-road group. Available in black or classic silver, construction is primarily carbon and aluminum. X0 can be configured for everything from technical riding to all-stops-out downhilling; choose from single- and multiple-ring cranksets and rotors from light 140mm to stop-the-train 200mm. Build up your ace wheels with the near-indestructible X0 alloy hubs, available in QR or your favorite flavor of through-axle, drivers available for all common cassetttes. Shifters include the light, precise 9-speed trigger shifter, weighing in at 225g of pure mechanism. For a little more luxury, choose one of the twist shifts, one available for every bar configuration.
A very good off-road group.
