The Air 9 aluminum hardtail blends the agility and efficiency of a pedal-friendly XC bike with the versatility, toughness and capability of a rowdy trail rig. Lightweight and snappy, poppy and peppy, the AIR 9 has plenty of stiffness to get you up to speed when you stomp on the pedals.

Hit the trail big with the 2-Star SRAM SX build, without a big hit to your wallet. Thanks to SRAM's outstanding SX Eagle drivetrain, you can bring every ounce of AIR 9 performance to bear at an affordable price point.
