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. 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. We thought about all of the ways people might take advantage of having 5.5” of travel coupled with a 29” wheel, and we 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. Best of all, build it how you want. 

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

CVA™ IS NOW PATENTED (U.S. PATENT NO. 7,934,739) CVA is an award-winning suspension design and now it is recognized with a US Patent. THE ONLY 29ER SPECIFIC SUSPENSION DESIGN CVA is the only suspension designed with 29ers in mind. For those seeking big wheels and CVA performance, Niner is the way to go - you won’t find this design on other bikes. EFFICIENT PEDALING IN ALL 3 CHAINRINGS CVA is designed to be efficient in all chainrings. Because of the location of the lower pivot (under the BB) chain torque effectively isolates and cancels out the forces acting to create inefficiency in pedal stroke. Niner’s own Constantly Varying Arc, or CVA™, suspension design is not just another version of the same old thing. It’s unique to Niner, designed in-house, specifically for 29” wheels. Although CVA does resemble some of the other parallel link bikes, in reality, CVA™ works very differently to isolate pedaling forces and remain fully active under all conditions. Many current suspension designs,

especially some parallel link suspension designs, maximize efficiency by concentrating their ‘instant center’ pivot location at or around the middle chainring. These designs assume that most of your pedaling will be done in the middle chainring and so are designed around this effective pivot location. This also means that there is some compromise to the suspension’s pedalability when NOT in the middle chainring (or when using a 2x10 set up). The better the design, the less noticeable these compromises are.

In order to isolate pedaling forces in a broader range of gearing choices, the CVA’s™ ‘instant center’ location is in front of the drivetrain. With the lower pivot under the bottom bracket, the force at the rear axle resulting from chain tension pulls the two linkages in opposite directions in all gear choices, effectively isolating the drivetrain from the rear triangle. In other words, when a rider cranks on the pedals, the chain is trying to pull the lower link down and away from the bottom bracket, and the upper link in its regular rotational path. Since the rear triangle is one piece, the result of these opposing forces cancels each other out, leaving the only outlet for chain-induced torque being rotation of the rear wheel, where it’s most wanted.

Past the rearward-most position at sag, the axle path

moves in towards the bike at a gradual, constantly varying arc, which insures that there is minimal chain growth throughout the length of travel. This also means minimal pedal feed back in the drivetrain while cycling the suspension, again, essentially isolating it from the fully active movement of the suspension design.

Another key component to CVA™ suspension’s active design is the low leverage ratio of shock stroke to suspension movement. This low leverage ratio decreases the amount of air or spring weight needed for any rider weight, which translates to smoother, more effective damping and less drag on the seals.

Ultimately, there are many variables in suspension – we believe that we have created a strong, 29er specific system, and that the best way to the best test is to go out and ride a Niner full suspension bike and see for yourself.
