Designed specifically for weight saving and performance, the Niner
AIR 9 Carbon RDO is the ultimate carbon hardtail race machine. A spin on niner's already light and race dominating AIR 9 Carbon. The RDO Embodies its name, ''Race Day Optimized.'' The similarities between the
AIR 9 Carbon and the AIR 9 Carbon RDO, pretty much stop with the sharing of the name and the fact that they''re both carbon.
The RDO has smaller diameter tubing for serious weight savings. It also uses a PF30 bottom bracket which adds to the weight savings. Niner''s universal CYA bottom bracket system, while being versitile does add additional weight because of the oversized sleeve in which the bottom bracket sits. Niner also chose to use molded bearing races instead of the metal inserts the AIR 9 uses for more weight savings. The PF30 and the Oversized headtube (1.125" - 1.5") to accomodate a tapered fork, add to the stiffness of the bike where its needed.
If you do a side by side comparison of the
AIR 9 Carbon and the RDO, the latter''s geometry looks more organic. Part of the reason for this is that the rear brake mount was moved to the chainstay. This will help evenly distribute force from braking and also save weight with the use of smaller post mounts. This not only makes the bike look cleaner and sleeker, but produces a smoother and quiter ride.
