NINER AIR 9 RDO FRAME (SATIN CARBON/SILVER) Taille M

Lighter and brighter

• Niner’s purest expression of light, stiff Race Day Optimized carbon fiber rules the racecourse.
• This efficient yet compliant frame makes the most of carbon’s unique properties to give you the best ride, no matter if you’re gunning for a podium or cruising local singletrack.

Exquisite engineering

• Niner's history is rooted in the evolution of mountain biking.
• From the introduction of our first hardtail more than a decade ago, we've worked tirelessly to push the limits of what people think is possible when it comes to the construction, geometry and handling of premium bicycles.
• The [R]Evolution that began with the RKT 9 RDO continues with the new AIR 9 RDO.
• Your big wheel obsession is now faster and more refined.

Designed for the ride

• The new AIR 9 RDO is our expression of the classic twenty-niner carbon hardtail.
• We've learned so much since the early days and applied that knowledge of geometry and materials to meet the ever-changing demands and riding styles of the modern mountain biker.
• The result? Our best race and high performance hardtail to date.
• The AIR 9 RDO embodies all the versatility, durability and performance you've come to expect from Niner.
• This frame's identity is refreshed with a bold design aesthetic.
• Continuing the lineage that began with RKT 9 RDO, the strong, overbuilt shapes that define the front triangle are made for stiffness and pedaling efficiency.
• But to keep the ride smooth, sleek tubes along the length of the cockpit and seatstays are slender and subtly curved.
• Topping it off, a 27.2mm seatpost offers rearward flex to take the edge of bumps in the trail.

Have it your way

• If ultralight simplicity, clean appearance (and a hard workout) are your jam, set up your AIR 9 RDO as a singlespeed.
• This frame is compatible with our BioCentric 30 bottom bracket system.
• You can set up your bike with a single cog and chainring, then tension the chain easily with our patented eccentric BB insert.
• We’ve been purist mountain bikers from the early days of 29-inch wheels and this frame has been one of our most popular for just this reason.
• The PF30 bottom bracket shell gives us plenty of options with regard to drivetrain, no matter your preference.
• And if you run a geared drivetrain, internal cable routing is super sano and easy to maintain.
• Even better, this frame is ready for the future with ports to use Di2 electronic shifters.

RDO carbon fiber

• Carbon fiber is common, but care, quality and attention to detail are not.
• Niner RDO carbon fiber is a cut above. We start with the best grades of raw carbon layered precisely according to the stress points on the frame structure.
• In construction, our process employs rigid internal molds and results in tighter, more consistent compaction of the carbon fabric.
• The result? Increased precision in wall thickness and reduced resin pooling in the final product.
• We can build more elaborate structures with better ride tuning, increased strength, outstanding durability, and less weight.

Full Sleeve cable guides

• No more fishin’. We built in end-to-end cable guides through the frame for easy installation and maintenance.

Protection where you need it

• Factory installed, integrated frame protection to keep your ride safe from harm, even when you’re in over your head.
