Ride it the way you want to with Niner’s proprietary Bio-Centric EBB technology and the CYA bottom bracket system. The Air 9 Carbon SPX can be built geared or singlespeed. Structurally, a full carbon frame, however utilizes alloy interfaces in critical areas, such as in the headtube bearing journals and bottom bracket.

This Niner is purpose-built to be lightening fast linked with keen handling and a frame material that dampens vibrations for a very forgiving ride. Find the fun in customizing this frame to your riding style and preference.


The performance of Niner’s innovative and award winning race geometry is unparalleled and apparent in the numerous World Championship titles Niner has acquired. Niner remains influential in new trends and technologies, refining the geometry where necessary while maintaining the precise handling, steering and stability capabilities that creates a confident rider and what Niner built their brand on.


Once the Bio-Centric EBB is installed into a 68 by 55mm bottom bracket, the result essentially becomes a 73mm bottom bracket width. The eccentric bottom bracket cups slide into an enlarged bottom bracket shell and are secured by 360 degrees of flush metal-on-metal friction. The cups are then tightened onto the frame by a hex bolt on the non-drive side cup that threads into the drive-side cup. The offset center allows you to rotate the cups and the location of the bottom bracket and in-turn chain tension, fine-tuning the bottom bracket.


The Niner crew has created a solution to the excessive standards in bottom brackets by developing the CYA insert adapter technology. This enables you to run multiple standard bottom brackets by using an adapter pressed into the frame’s BB shell. Niner’s ingenuity solution allows the possibilities to run a variety of crank and bottom bracket combinations. No need to conform to just one!

Keep in mind, the different CYA inserts adapters are available for Press Fit 30, BB30, BB92, standard English threaded bottom brackets. CYA inserts do not work with all Niner models. Compatible models are: Air 9 Carbon CYA.


With change comes improvement, tapering the headtube increases steering precision and torsional stiffness in the front of the bike. This not only improves the handling, but also builds the confidence of a rider shredding corners, descending into a finish line or bombing boulders in the woods.

Niner has prided themselves on having 100% dedication to the 29” wheel format since 2004 but has recently released (2016) a 27.5+/29er frame into their lineup. Their commitment goes beyond the bicycle product, founder Chris Sugai has made it a mission to continuously support the International Mountain Biking Association, also known as IMBA. Knowing that the mountain biking community needs places to ride, if there wasn’t there would be no Niner.

Their main headquarters are found in Fort Collins, CO where daily magic and mojo shine through. Assembly and shipping of complete bikes for resale are done in California, showing a real commitment to the American based cycling industry.

We are excited to carry the Niner brand not only because they are some of the highest quality rigs on the market but also because of the beautiful mountain biking community they have helped mold. Starting with their in-house crew and kick-ass work surroundings in their Colorado location. Become a Ninerd by riding and supporting your passionate brand by yelling it from the mountain tops as you cascade downhill. New to the Niner brand or not you can visit any of their bike demos. You don’t have to just drool over their bikes, throw a leg over them and “PEDAL DAMN IT!”
