In pedigree of mountain bikes, the Niner Air 9 RDO is a highly sought out performance machine. Niner has made themselves the 29er expert, as well as mastered the hardtail geometry for this wheel size. Demonstrating their excellence through design.

Featuring a fully internal cable routing system integrated within the head badge, conscious layup of RDO carbon, tapered headtube for front end stiffness and steering confidence, ideally placed rear disc brake mounts, and a PressFit 30 (PF30) carbon bottom bracket shell.

Ultimate weight saver, the PF30 bottom bracket shell eliminates need for an alloy insert still allowing for 24mm or 30mm spindle cranks to be installed. Rocking the rear brake mount inside the chainstay stiffens the whole rear end.

Niner’s Race Day Optimized Carbon Compaction System utilizes a rigid internal mold resulting in a more targeted and consistent compaction of carbon layers allowing an increase in precision for wall thickness and a reduction of resin pooling = reduction in weight, smoothing out the wrinkles and loose fibers toughening up the frame! This process basically makes this their top of the line product. Pedal swiftly up the mountain on RDO carbon and you may not want ride anything else.

Make this bike into your own by outfitting it to suit your riding style.

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!”
