Niner WFO 9 Frame

The WFO 9 boldly goes where no 29er has gone before. This All-Mountain masher is ready to shed some light on what 29” wheels can do with 5.5” of travel. The progressive “confidence inspiring” geometry provides slack enough angles to get you comfortably down steep and rocky terrain, yet not so slack that you’d find it hard cornering tight turns or having to climb. The WFO was constructed with hydroformed tubing which allows for careful shaping and control or wall thickness, optimizing strength and stiffness in key areas. These hydroformed tubes paired with the tapered headtube and 12x142mm rear axle ensure the WFO remains stiff and strong from head to toe.

The WFO will not handle like any other long-travel bike you’ve ridden before. The 29” wheel platform provides a lower rolling resistance and the ability to get down the most rutted sections with ease while the tapered headtube reduced fork deflection, keeping your line straight and true. The long-travel and big wheels will eat up just about anything that gets in your way of having a good time. You’ll find yourself getting down some seriously sketchy sections quicker and easier than before.

The WFO 9 features Niner’s patented CVA suspension. This is the only suspension created for the sole purpose to be used on 29” bikes. In other words, they did not modify suspension that was created for a 26” wheel. The CVA suspension was created with the goal of efficiency. Due to the location of the lower pivot bolt, chain torque effectively isolates and cancels out the forces acting to create inefficiency in pedal stroke. The rider will be able to use all three chainrings. CVA has excellent small bump compliance, to ensure that your ride is smooth as well as fast.

Independent Review

"I found myself carrying unprecedented speed through sections of trail that I know well. More impressive, cornering grip in the loose, sandy turns was very predictable. By the end of my first ride out , I was carrying more speed on almost every part of what is a very challenging trail than any other bike I’ve taken down it to date. To say I was impressed is an understatement."
