Niner AIR 9 RDO


Niner’s history is rooted in the evolution of mountain biking. From the introduction of our first hardtail, we’ve worked tirelessly to push the limits of what people think is possible when it comes to the construction, geometry and handling of premium bicycles. The [R]Evolution that began with the RKT 9 RDO continues with the new AIR 9 RDO, Bigger is Still Better, your Big Wheel Crush is now faster and more refined.

We’ve learned so much since the early days and applied that knowledge of geometry and materials to meet the ever-changing demands and riding styles of the modern mountain biker. What we’ve created is undoubtedly the best race and high performance hardtail we’ve made to date, one that will give you all the versatility, durability and performance you’ve come to expect from Niner.
