The WFO 9 RDO: It's F*cking Back.

Join Kirt Voreis and Kyle Warner for a shred on the new Niner Bikes WFO 9 RDO. Brought to you by the mad mind and virtual reality of our very own cousin Kirt.

More than a decade after the first W.F.O. 9 defined the category and set a benchmark for what a long-travel 29er could do, we’re bringing it back. The 2021 WFO 9 RDO draws on our years of 29er evolution to establish a new paradigm of unbridled, big-wheel domination. Reborn with 170mm of stable CVA suspension, a 180mm-travel fork, adjustable geometry, increased frame stiffness, and our signature RDO carbon fiber, the new generation of WFO 9 RDO is an enduro-ready brawler with the pedaling prowess to get you to the top in style.

Loyal Ninerds feared that it was extinct forever. But the WFO 9 RDO was only dormant, lying in wait, evolving and mutating to reemerge as the apex predator of long-travel 29ers. That first W.F.O. cut fresh 29er tracks in too many ways to count. Technologies that we take for granted today were pioneered in that legendary frame. What a difference a decade can make. The strongest remaining genetic link between our original and this new WFO 9 RDO is simply an unquenchable appetite for wide, full open, edge of control, speed.

All the descending capability of a 170mm travel 29er is fully expressed in this new WFO 9 RDO. Yet any detectable trace of the dreaded “climbing compromises” chromosome is edited out. We all know that modern enduro bikes have to manage descents into madness on the scale of World Cup DH tracks. Yet they also need to get you efficiently back up to the top when pedaling is your only option. Which, let’s be honest, is usually the case.

On the WFO, a trunnion mount shock adds width (and therefore stiffness) to the frame and linkage. The shock bolts directly to the rocker link with bearings at the interface. This allows for extra-smooth articulation through the entire rocker sweep of 40-degrees during suspension travel. Furthermore, trunnion shocks occupy less space, allowing a compact form factor.

In consideration of the dueling demands riders expect from the WFO 9 RDO, subtle refinements to the kinematics give it superior pedaling behavior despite 170mm of travel on tap. The leverage ratio curve starts at 3.0, hits 2.4 at 67% travel, then hits 2.6 at full travel. It’s also tuned for a slightly falling rate (about 6% in the last 33% of travel). If you’re running an air shock as the bike is spec’d, the overall rate in every phase of travel feels consistent and natural in every phase of travel. Even with a coil you won’t feel as though the bike is bottoming out.

From a distance, the new WFO 9 RDO looks like a fraternal twin to the trail bike in our line, the popular and handsome RIP 9 RDO. However, Niner’s characteristic full-suspension frame cosmetics deceive your eyes. A closer look reveals that the new WFO 9 RDO is clearly the bigger, brawnier sibling that got its square-jawed genes from cousin Vinnie’s side of the family.

 I don’t understand the negativity Niner is getting for this release. Bike looks sick. Voreis is a legend, a goofy one at that. They are clearly having fun with it. I’d prefer this bike over a lot of other stuff out there.

Different folks with alllll the same strokes... is how the saying goes or something.

 Pinkbike comment section hive mind. Niner makes a fun bike, they’re priced high which makes everyone with their Bronson Rs feel better about their purchase.

 I think that the owner/founder was a bit of a hard sell at first. I had a change of heart when he literally had a "humble pie" video. Anyone who is able to admit when they made a mistake is worth giving a few chances. Kirt is also worth a watch or 5.

 They kinda just stalled out for a while. For a brand that was pushing boundaries (that's why I bought the 2nd gen WFO), their innovation left the building as they went through a financial struggle. New one looks good, and a million points to Kirt for his acting!

 I would much rather have Kurt screaming in a "this is definitely not serious" accent and shred than watch a 45 minute extraterrestrial themed Spielberg production chock full of lame references and wattz/gainz taking itself waaay to seriously and seemingly aimed squarely at the bro club that produced it/super rich finance bro's with disposable income. The fact that Kyle is in there is just icing on the cake. Such a nice rad shredder.

 I'll bet this bike f'ing out performs most down hill bikes. Niner builds a seriously good mountain bike. My Rip 9RDO with 140mm travel is enduro worthy at any level, solid chassis frames.

 I really loved my WFO (green one) back in 2013 & 2014. Killer trail bike and it really wasn't until I took it to Angel Fire that I felt the head angle might not be slack enough and the seat tube too long to get the seat low enough. Nice to see the WFO is back. Way to go Niner and always good to see another local Colorado company out there.

 nope, it's still ugly as sin and dated. 480 is the max reach. guess they didn't anticipate selling it to anyone over 6ft.
  • 1 2
 Ugly, but that standover height wins me over.

 Please make this in 27.5 like the RIP! I’m too old to go back to 140, too young for wagon wheels
