SRAM XX Mountain Group

The 2016 SRAM XX Mountain Group is a top-end cross-country MTB racer's group. Lightweight, tough, and high-performance, with options in shifting, suspension travel, rotor size, cassette and crank gearing, crankarm length, and derailleur cage. XX offers a clean-shifting, reliable under duress, 2x10 drivetrain, with gearing appropriate for 26", 27.5" and 29er wheel sets. Rock Shox' Monarch shock and SID fork provide 100-120mm of very smooth travel with remote lockout. Components are constructed from carbon, aluminum, and magnesium, material purpose-chosen.
A very good racer's off-road group.
