Niner Air 9 RDO 5 stars - 2019, X-Large

This bike represents everything a top-tier hardtail should be: ultra-lightweight, efficient, and built for pure speed. The Niner AIR 9 RDO frame in carbon delivers incredible stiffness and responsiveness, making every pedal stroke count. Paired with a RockShox SID Ultimate 120mm fork, it handles technical XC trails with precision and confidence.

The drivetrain is Shimano XTR 1x12, the gold standard for performance and reliability, offering flawless shifting even under load. Stopping power comes from Shimano XTR hydraulic brakes, ensuring control in all conditions. The Roval Control SL carbon wheels keep weight low and acceleration snappy, while Schwalbe Racing Ray tires provide the grip and rolling speed you need for competitive XC riding.

Every detail screams premium—from the ENVE carbon cockpit and stem to the OneUp dropper post for added versatility on varied terrain. At 21 lbs, this is a featherweight rocket designed for riders who demand the best.

With an original MSRP of $8,499 and only about 1,000 miles of use, this bike has been well cared for and is 100% tuned and ready for action. It shows a few cosmetic marks from normal riding, but mechanically it’s in excellent shape.

This is your chance to own a race-ready hardtail with a dream build at a fraction of the original cost.
