Nice bar. Not too flexy, not too stiff. Takes the vibrations out of the ride, and feels nice on your hands. I really like the width and sweep combination. A little expensive considering other bars like Thomson are $50 cheaper.
I bought this to replace the standard Niner carbon flat bar. I have a Air 9 RDO and decided to get the matching RDO handlebar verses the standard Niner flat handlebar. I had them side by side. The only difference beside saying RDO is that the carbon walls are thinner on the RDO than the standard carbon bars. It makes me nervous how much thinner they are. Time will tell if it holds up.
