Niner Air 9 Carbon Frame

The Niner Air 9 Carbon is Niner's latest iteration of the renowned Air 9 frame. Niner has proven year after year that they've got the 29er hardtail geometry down to a science, which they are demonstrating yet again with the new Air 9 Carbon. Although it's technically not an RDO, it borrows the mold and several other features previously only seen on the Air 9 RDO frame.

The Air 9 Carbon features internal cable routing (the frame is Di2 ready and side swing front derailleur compatible), thinner tube profiles, smaller junctions, carbon molded headset races, a low profile disc brake mount, and a PF30 carbon bottom bracket shell. Niner decided to go with a PF30 bottom bracket shell for the Air 9 Carbon geared-only carbon hardtail. The PF30 bottom bracket shell allows for 24mm or 30mm spindle cranks to be installed, however this frame is not compatible with an EBB (hence €˜geared-only').

To keep this horse tame, Niner continues to use tapered headtubes in order to maintain a stiffer front end to drastically improve the overall handling and control. Additionally, Niner also decided to go with a very sleek integrated headset that is lightweight, easy to install and maintain.

This version of the Air 9 Carbon is the first to feature a 12 x 142 rear hub spacing allowing a thru axle to be used as an added measure to increase the overall stiffness of the ride while shedding roughly 50 grams. Other improvements making their debut on the Air 9 Carbon include its 2.4" tire clearance versus its previous 2.35" clearance, as well as the lighter headbadge that sheds valuable grams without expensing the Niner charm.

The new Air 9 Carbon is a stellar frame that anyone can and will enjoy. Although it's technically not €˜Race Day Optimized', this bike is as much at home on the XC course as it is enjoying the scenery on your weekend loop. By providing their proven hardtail geometry in a lightweight carbon frame, Niner definitely knew what they were doing when they designed the new Air 9 Carbon.

budget racer
I'm a high school league racer who doesn't have the means to ride the latest and greatest S-works, but I can tell you i've beat people on shiny new $10k+ bikes on multiple occasions. The frame is bulletproof, it't not nearly the lightest but neither am i, nor do i really care considering how cheap it was to purchase. It's responsive, fast, and Niner really worked their magic on this bike, the geometry is flawless.

Great frame at awesome price
Love my new Air9 Carbon . Been contemplating buying this bike for a while. A few years back I ordered the same frame to be built by another online bike company. Excited about new purchase then I started to notice some issues with what I thought I was getting and what the order said I was going to get. I cancelled the order. With many plea's from the other online dealer to make the purchase at even more of a discounted price. They lost my trust. It's taken me a while to pull the trigger. Thank you Jenson USA for your help in purchasing the right bike for me.

Stepping up from aluminum!
Even though I only been on a few rides on this frame, the comfort level has drastically improved from the aluminum frame that I was riding. I can tell that there will be many more enjoyable mile to be had on this frame.

I want to set this frame as 1x. Looking at shimano XT group set and the cassette is 11-42. Will this work on this frame?
Ryan on Oct 4, 2016
BEST ANSWER: That is my plan exactly! But I will build this bike over the winter as deals become available and at this point I only have the frame. If I remember correctly the description of the frame on the website had detailed info on compatible drivetrains.

What is the difference between this frame and the Air 9, and what size would I run if I'm 6 feet tall with an inseam of 30 (I'm a 56-57 in a road bike)? Thanks.

BEST ANSWER: Hi there, Niner sent us their flagship feather-weight Air 9 RDO (Race Day Optimized for those not in the know), stacked with some of their house components, XTR drivetrain, and RockShox’s RS-1 carbon inverted fork. The RDO definitely puts the purpose of this bike into perspective when it comes to “Race Day Optimized”. Check out what made me grin… and what made me cringe riding this race machine…

Can I use a 1 1/8" straight fork steerer tube on this frame?
JerJer on Aug 23, 2016
BEST ANSWER: Non-tapered fork for a tapered head tube can be used with an adapter. Just make sure you get one from your headsets manufacturer. Crown races usually aren't cross compatible.
