Wide, Full Open. That’s what the name means. Let ‘er go, full throttle, don’t slow down for anything, that’s what the name implies. Niner made this bike with 5.5” of plush CVA™ suspension technology underfoot, there’s nothing stopping those 29” wheels except the human instinct to live another day.

The W.F.O. 9 went through exhaustive testing and refining, including a first for a 29er frame: a tapered headtube for increased front end stiffness and strength. Niner thought about all of the ways people might take advantage of having 5.5” of travel coupled with a 29” wheel, and then designed the W.F.O. 9 to handle them all. A custom S-bend hydroformed downtube allows the use of both coil and piggyback shocks, offset bottom linkage makes room for an ISCG mount, making this frame the first 29er to be compatible with the all new SRAM Hammerschmidt system and other chain guide systems and an optional 150mm rear spacing increases rear wheel strength and stiffness. Best of all, build it how you want. Order the W.F.O. 9 with 135 or 150 rear spacing and then choose from our shock options or order without a shock.

Whatever your needs, from aggressive all mountain to big hit, Niner's W.F.O. 9 will keep you pinned all the way down some of the gnarliest terrain you can throw at it.
