A hardtail with the DNA of a trail bike.

A cross-country race bike hits the trails in the AIR 9. It's lightweight, snappy, and durable. The aluminum frame offers maximum comfort and stiffness, and incredible pedaling power. It comes in single-speed and geared options.

The Air 9 comes in just one build kit, the 2-STAR SRAM SX EAGLE, and in only one color combination (silver + Baja Blue). It's also available as a frame only option and in an RDO version.
