You are looking at my very much loved Niner Air 9 RDO Carbon fibre hardtail frame. Colour: Carbon / Red. Condition: Very good condition.. The odd mark here the there.. Has had helicopter tape on most part which I have now removed (small section near the bottom bracket has pull some of the lacquer but only superficial). No crashes, no cracks. Owned from new but have now gone to full suspension. When built up this was a sub 20lbs hardtail.. Super light and fast! Thank you for looking and please see my other items. Product description Niner AIR 9 RDO. 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. Riders will see the results of a 10 year refinement process in everything from geometry to the carbon frame design to the technical details. 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 (one-quarter of a pound). The shapes of the Air 9 RDO frame draw from our long history in carbon fiber design. The rigid sides of our signature downtube and top tube shapes maximize torsional stiffness, with buttery smooth ride quality achieved via the flat sections on each tube, which act like leaf springs. Chainstay and seatstay shaping also benefits from our years of hardtail expertise they are one hundred percent designed for weight savings and ride quality via a minimalist carbon layup that, because of our RDO carbon Compaction process, still meets the most rigorous standards for mountain bike safety. 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.
