| Competition is your oxygen. The Air 9 RDO is your answer. Niner’s flagship racing hardtail reaches new, ultra-refined heights.
The new Air 9 RDO is a product of almost a decade of refinement and testing, courtesy of Niner’s racing and engineering programs.
RDO CARBON COMPACTION SYSTEM
The Air 9 RDO’s sleek carbon frame design benefits from years of Niner engineering development, process improvement and testing – via both Niner’s in house test lab and independent resources.
The Air 9 RDO is beautiful from the inside out via Niner’s Carbon Compaction System. Now used throughout the Niner RDO lineup, this CCS utilizes rigid internal molds and results in tighter, more consistent compaction of the carbon layers, yielding increased precision in wall thickness and significantly reduced resin pooling in the final product, allowing us to aim for better ride tuning, increased strength and durability along with the significant weight reduction that results from a more efficient and precise process. Even with the addition of a rear maxle, the Air 9 RDO is over 100 grams lighter.
DESIGN
The shapes of our Air 9 RDO frame draw from our long history in carbon fiber design – in particular from our experience in building light, strong hardtails with velvet off road ride-quality.

PERFORMANCE GEOMETRY
Niner’s hardtail racing geometry is one that has has garnered multiple national championships via the original Scandium Air 9, a Singlespeed World Championship via the Air 9 Carbon and World Cup podiums and national series race wins via the Air 9 RDO. Though time tested, Niner’s geometry has not remained stagnant - it has seen continual refinements to account for new technologies and to accommodate new fork travel lengths, while still meeting EN Safety standards for increased forces. The new Air 9 RDO can safely accommodate forks with up to 120mm of travel, while maintaining the stable, precise steering and handling that lets your relax, be confident and focus on being fast.
PRESS FIT 30 BOTTOM BRACKET
The AIR 9 RDO utilizes the Press Fit 30 standard, the larger shell mates beautifully with the larger carbon downtube for elegant looks and efficient power transfer so crucial in a race bike. Additionally, this allows for the use of the stiffer, lighter crankset designs that fit the PF30 standard.
