    Your ride has arrived.

    When buttery smooth trails transition to the rough, it's nice to have a little bit of squish up front to soften the ride. For those of us who love the adrenaline rush of deftly navigating rock gardens and live for a big dose of hardtail speed, Niner brings the 2017 Niner Air 9 RDO 5-Star XTR 1x Complete Mountain Bike to the table. With tweaked geometry and boosted axles, this whip is ready to rip. As the name implies, this build sits at the top of the Niner pyramid, kitted out with Shimano's top-end XTR one-by drivetrain and hydraulic brakes, a show-stealing RockShox RS-1 fork, Niner's carbon fiber RDO post, and a set of smooth rolling carbon fiber hoops wrapped in versatile Maxxis Ikon tires.

    The most notable changes to the frame include a lower handlebar height, giving the Air 9 a nudge towards the venerable RKT 9 RDO's aggressive positioning. It has a longer cockpit and slacker head tube, making for a frame that handles deftly on knife-edge lines and jumps the second you need it to. Compared to the previous Air 9, the chainstays scrunched in by 4mm to 435mm for lightning fast acceleration and nimble handing without crossing over into jumpy, squirrely territory.

    The new Air 9 RDO also sizes down its seatpost diameter to 27.2mm to take advantage of that little bit of extra flex and resulting comfort found in a narrower post. Niner pushes this benefit to the max by pairing this frame with its RDO Carbon Fiber Post, which is specifically trail-tuned to provide additional flex to soften the ride.

    Out back, this year's model now boasts a 12 x 148mm Boost axle width, keeping in line with current trends for wider axles and stiffer wheelsets. Niner also tucks the brake caliper mounts on the chainstay, neatly within the rear triangle. This makes sense from a frame building standpoint, as the seatstay is generally the burlier of the two rear stays and the placement protects the caliper somewhat in the event of a crash. We also think that particular placement just looks better than an ungainly bump hovering above a seatstay.

    As with Niner's other RDO offerings, the Air 9 RDO is constructed using Niner's Carbon Compaction System (CCS), which gives Niner complete control over tube wall thickness across the frame. This makes for tube walls that are virtually perfect, reduces the amount of materials required, and eliminates excess resin build-up. The result is a claimed 10% weight reduction, which is a nearly unheard of leap between model years.

    Boosted!

    • Familiarity: I've used it once or twice and have initial impressions

    Niner was the first to the part in putting the new Boost spacing to use on XC race bikes with the RKT, and now they've done it with the brand new Air 9 RDO! Shorter chainstays and wider rear spacing means a more responsive bike under load, especially out of the saddle. A more slack front end provides better handling and a slightly more relaxed feel than the 2016 model.

    If you like the previous Air 9 RDO, you are going to love the new setup. More responsive, easier to handle at high speed, and lighter; what more could you ask for!?

    If you have any questions, please feel free to reach out to me directly.

    You definitely can! It would be easier with the style of the cable outlets to the frame, to use a mechanically actuated post (pretty much anything other than a Reverb). On each side of the frame, there is a cable entry point covered with a piece of rubber, that can be pierced by two different pieces of cable housing, so you could even run a 2x drivetrain, and the dropper!

    Please let me know if you have any additional questions!
