Niner Air 9 rdo bike review

Niner Air 9 and Air 9 RDO are two fast and capable hardtail bikes made by the famous American bike brand – Niner.

They are considered by many to be the perfect mixture between XC and trail bikes, which makes them incredibly versatile at a certain type of riding.

The Air 9 is the more affordable choice, intended for XC and Trail enthusiasts, who do not plan to enter any pro races, but are just looking to spend as much time in nature as possible and have as much fun as possible on rides and in amateur events.

On the other hand, the Niner Air 9 RDO is a race-ready machine with a slightly different geometry than the Air 9. With the right pair of legs on its pedals, it can win any competition that it finds itself in.
