New Air 9 RDO from Niner Bikes – A Racing Thoroughbred

29er

New Photos Added (courtesy of ProBikeSupply)

Introduction by Francis Cebedo:

The Niner Air 9 RDO picks up the baton from Air 9 Carbon and delivers a sleeker and lighter bike.  The Air 9 RDO is half a pound lighter and tips the scales at about 2.5 lbs for the frame. The tubes are smaller, suggesting a more comfortable and compliant ride. The frame still has huge tubes compared to the competition and it is one of the best looking frames in the growing field of carbon hardtail 29ers.

At $2099, it is pricey but we have no doubt Niner will have a hard time keeping this exotic bike in stock.

The Air 9 RDO is a thoroughbred – a no-nonsense instrument built for speed and performance. An extension of our form-follows-function philosophy, no curve is out of place on the newest Niner. And while looks are important, true attraction begins as soon as you push on the pedals and the Air 9 RDO goes flat out.

Refined Design

The Air 9 RDO is specifically intended as a geared racing bike. With this in mind we referred to the purposeful lines of the Air 9 Carbon but reduced diameters and trimmed profiles throughout.

  • Compared to the CYA bottom bracket shell of the Air 9 Carbon, the smaller PF30 shell of the Air 9 RDO suggested smaller junctions and negated the need for an alloy insert.
  • The rear brake mount is tucked inside the curving stays to distribute twisting forces evenly, permitting smaller caliper mounts and decreased wall thicknesses.
  • Even the headset races in the headtube are molded carbon – we shaved grams wherever we found them.

The net result? A 1125g Niner frame that is going to knock your socks off.

Tapered Headtube

The benefits of a tapered headtube aren’t just for riders of long travel bikes. XC racers and riders also see significant advantages, which is why we incorporate the technology in all our new frames. By using the newest tapered steerer suspension forks, we create the stiffest front end possible – leading to increased steering precision as you carve a corner and descend toward the finish line.

The integrated headset used in the Air 9 RDO is light and simple. Installation, cleaning and maintenance take seconds rather than minutes, a boon to anyone who queues up at the starting line without a team mechanic.

Internal Shifter Routing

New aluminum headbadge designed for full-length housing simplifies cable changes and protects cables from the elements.

PF30 Bottom Bracket

There are several BB standards to choose from – for our dedicated geared only race bike we like PF30. It’s compatible with any BB30 crankset and the bearing cups are delightfully easy to install. The oversized 30mm spindle is light and resists the torque of even the mightiest Ninerds. Oversized bearings spin longer and smoother between overhauls. The plastic cups of the PF30 BB system don’t require a machined aluminum bottom bracket shell insert, allowing a minimalist carbon construction.

Real World Weight Savings

Is it lighter than the Air 9 Carbon? Yes, quite a bit. The Air 9 RDO averages 1125g for a Medium frame (without seat collar or protective downtube tape). That’s over a half-pound less than its brother. If getting there as quickly as possible is your game, you will want to throw a leg over the Air 9 RDO.

The first 50 frames are available as a special edition XTR bike with matching Sid World Cup fork and components. The Air 9 RDO will later be available with standard Niner buildkits or as a frame only.
