2011 niner w f o 9   2011 Niner W.F.O.9

Niner ushers in the first tapered headtube on a 29er with the 2011 W.F.O.9. Wide Full Open comes with a 5.5″ CVA suspension (Constantly Varying Arc), hydroformed tubing and options of 135 or 150mm rear spacing.

The CVA suspension design is to accomplish a bike that has a wheel dialed in on the different arcs it runs with, making it pedal neutral as well as brake neutral. The Niner W.F. O.9 keeps its gear in tune with each other so as not to affect the performance of the suspension.

The downtube’s S-bend gives way to an ISCG mount that makes the W.F.O.9 Hammerschmidt compatible. As for the shock, it is coil or piggyback compatible.

The 2011 W.F. O.9 has two options for build kits. A Shimano XT kit has a MSRP of $2678 while the SLX is priced at $2299. The frame retails for $1899 (135mm) and $2099 (150mm).
