An aluminum hardtail with the DNA of a trail bike. If a cross-country race bike met a rugged trail bike in the woods, their love child might look a lot like our AIR 9 aluminum hardtail. This bike blends the agility and efficiency of a pedal-friendly XC bike with the versatility, toughness, and capability of a rowdy trail rig.

Build it your way with the AIR 9 frame-only option. The aluminum frame is ready for the best parts you can hang on it. Nearly any drivetrain you can imagine is within reach, and Boost hub spacing gives you freedom for all the wheel and tire options you could want.
