Niner WFO 9 4 Star X01 Bike

Niner WFO 9 4 Star X01 Bike

If you mentioned the concept of a 29er on big terrain a few years ago, you undoubtedly would’ve been laughed at by riders and industry professionals everywhere. Here we are in 2014, and the Niner WFO 9 is one of the industry’s first long-travel big-wheelers, and boy is it equipped and ready for a great time!

This All-Mountain masher is ready to shed some light on what 29” wheels can do when you give them nearly 6” of travel to play with. The progressive “confidence inspiring” geometry provides slack enough angles that you might find yourself contemplating on racing this beast Downhill, yet not so slack that you’d find it difficult cornering tight turns or climbing. The WFO is constructed with airformed tubing which allows for careful shaping and control over 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 rear axle.

The WFO does not handle like any other long-travel bike you’ve ever ridden before. The 29” wheel platform provides a shallower angle of attack when riding over obstacles, which increases your ability to get down the most rutted sections with ease, while the tapered headtube reduces fork deflection, keeping your line straight and true. The long-travel and big wheels will eat up just about anything that dares to get in your way. You’ll find yourself getting down some seriously sketchy sections quicker and easier than before.

The WFO 9 features Niner’s patented CVA suspension which is the only suspension system 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 crafting an efficient suspension platform for the 29" bike. Due to the location of the lower pivot bolt, chain torque effectively isolates and cancels out the forces that can create inefficiency in pedal stroke. The result is unparalleled pedal efficiency, and remarkable sensitivity. CVA has excellent small bump compliance, to ensure that your ride is as smooth as it is fast.

Outfitting the Niner WFO 9 4 Star is the highly sought after SRAM X01 group. X01 brings SRAM’s 11 speed mountain drivetrain to the masses with a lower price point without sacrificing performance. X01 is slightly heavier than XX1 (the difference is under 100g) but is still much lighter than any 2x10 setup out there while still offering a wide gear range, thanks to the 10-42T X-Dome cassette. The new X01 cranks feature carbon arms and a removable spider (much like the X0 cranks) along with SRAM’s new X-Sync tooth profile which acts as a built in chain guide system. The rear derailleur’s X-Horizon design eliminates any vertical movement, reducing shift forces and preventing “ghost shifting”. The X01 drivetrain brings the latest and greatest SRAM technologies to your beautiful Niner WFO 9 bike, offering a simple, clean, and more importantly, reliable drivetrain.

With its slack headtube, shorter top tube and chainstays, long-travel, and SRAM X01 set-up, after it’s all said and done, the Niner WFO 9 is the closest thing to a downhill 29er. The larger 29” wheel size gobbles up roots, rocks and ruts so much its almost unfair, while the new geometry allows it to still handle with the precision and flickability of its smaller wheeled relatives. The CVA suspension system makes climbing much more efficient, reducing bob and maximizing power transfer. Between the bigger wheel size, the nearly 6” of travel, and the new geometry and suspension system, the WFO 9 is faster and smother, both up hill and downhill; a pure bred Enduro machine!
