Niner showed Pinkbike its prototype WFO 9 a while back at the Enduro World Series in Winter Park, Colorado. The real deal was unveiled at Eurobike, and it looks to be a winner. The WFO-9 follows the profile of Niner's recent mid-travel 29ers like the Jet and RDO, but there have been significant improvements and changes throughout the new chassis in order to stretch the suspension travel of the welded aluminum frame to 150 millimeters. The WFO 9's top tube has been shortened 20 millimeters to help center the rider between the wheels, and 20 millimeters has been shaved from the head tube to lower the handlebars. With a 160 millimeter stroke RockShox Pike RCT3 fork, the WFO's basic geometry lends itself well for gravity-oriented riders. The head angle is 67 degrees, while the calculated seat angle is around 75 degrees, depending upon the saddle height. Niner proudly states that the new WFO 9 is intended to be a gravity bike for bike park senders, but with effective pedaling action from its CVA dual-link suspension and a claimed weight of 28.7 pounds, Niner adds that is an near- perfect choice for European-style enduro racing. WFO 9s will arrive at dealers around December '13, with the price as-shown pegged at $4999, and the frame and Monarch RC3 reservoir shock set at $2099 USD. Colors are Atomic Blue or Racer Red.
ConstructionNiner claims that the WFO 9's stand-over height is only 27.5 inches
(40cm), which is low for a short-travel XC bike. Even if it were only close to that number, that is outstanding stand-over clearance for a 29er of any type. The chassis is intended to fit tires up to 2.5 inches, although the use of the largest DH carcasses will eat up most of the bike's mud clearance in the rear, where much engineering was done to keep the WFO 9's chainstays short, while guiding its massive 29-inch tire away from the rider's bum at full compression. Shod with Schwalbe 2.35-inch Nobby Nic tires, which is one of the largest in its class, there is barely one centimeter of air between the rubber and the frame in all directions. Niner's designers wanted the WFO 9's rear end as short as possible to give the bike an agile feel in the turns. Niner's choice of the travel-adjustable Pike RCT3 fork allows riders to drop the fork 35 millimeters, steepening the steering geometry by over one degree and lowering the handlebar by about one and a half inches. Future enduro racers can use the feature to transform the WFO into a better climber for transfer stages.
The chassis is designed exclusively for a single-chainring drivetrain and thus, there is no provision for a front changer. The seat tube is rectangular where a band clamp would normally sit. Niner provisions the WFO with an ISCG-05 chainguide mount and cable routing for an internal-style dropper seatpost. Why Niner does not furnish dropper posts on its technical trailbike models is a mystery to us. Be sure to calculate the price of a dropper post into the final purchase price of this
otherwise perfectly spec'ed machine. Looking at the frame's curving tubes, there is evidence everywhere on the chassis of Niner's air-form process which uses heat and pressure to shape its aluminum pipes to better handle the various stresses that ravage the chassis in the downhill environment. To maximize the welding area of the shortened head tube, Niner uses internal head set cups. Cane Creek AngleSet headsets will fit the WFO 9 should you decide on a custom steering angle.
Standout ComponentsNiner will offer the WFO at two price points and as a frame and shock. The top, Four-Star build shown here is quite affordable considering its direct competition in the AM/enduro segment. The bike is built around SRAM's X01 transmission with the X1 aluminum crank option and a 32-tooth chainring, and as we documented, the bike rides on the best mid-travel suspension items to come out of RockShox in two decades. It rolls on a 29-millimeter-wide Stan's ZR Flow EX tubeless wheelset, which provide excellent torsional stability for large-volume tires. The seatpost is a Niner item, topped by a comfortable Niner-logo WTB Volt Race saddle. Brakes are Avid's X9 Trails, with powerful four-piston calipers squeezing 160 rear and a 180-millimeter front rotors. Beyond the missing dropper seatpost, there is little if anything left to want from the WFO 9's build. All accounted for, Niner's new WFO 9 looks to be a winner.

I'll be in the cue..
are ha getting slacker and slacker or is it only my brain??
"Rather, I’ll let the W.F.O. stand on its own merits as the fastest All Mountain bike that I’ve had the pleasure of riding down a proper DH line."
"...the WFO became my go-to ride when I wanted to get sideways on rowdy trails."
"In fact, flying the big 29′er felt totally natural back to back with my DH rig"
"The speed, stability, and traction of the W.F.O. had me feeling rather invincible and honestly, the bike handled every crazy line I had the balls to try without complaint."
Seems like a little more than sugar coating a negative review. Not sure what article you were reading...they must teach reading comprehension differently up there to the north.
"There are so many data points that are much different than any 26″ bike that I’ve ridden that it would be pointless to try and draw a simple parallel between them. Rather, I’ll let the W.F.O. stand on its own merits as the fastest All Mountain bike that I’ve had the pleasure of riding down a proper DH line."
I am more than sure that the other stuff you pulled from the article talks in generalisations about all mountain riding.
either that, or he's contradicting himself. In that case, a poor article then.
That's exactly what you got and you're still arguing?
You clearly already know what your conclusion on 29ers is, but your trying to argue an invalid argument from a flawed, indefensible position.
As all you, 26" For Life", morons continue to try to make this argument, you just sound more and more like guys living in your parents basements as the world passes you by.
At some point you just have to realize, you can't argue with stupid.
Anyone who posts on this website clearly has issues...you just also happen to be a moron.
The old one ripped...the new one will surely be a ripper too.

A friend of mine here had a 2-step until last year he loved it so much; great platform.
So, their design was nothing revolutionary and just a reworking of an existing design like the DW link. Patentable - well yes, because nobody challenged it at the time, but actually not unique or new, really.
Look at the linkage, rear triangle and wheel. Where are you gonna chop an inch off? if you can do all that AND keep the the handling the same (for a AM bike), you can have my inheritance.
Go!
Oh and DH bikes and wheelbase? Chainstay has an incredibly miniscule impact on wheelbase compared to virtually anything else. The only thing it really affects is the difference between the BB and the rear wheel, which affects the handling of the bike and its ability to change direction easily. Top tube length/reach, head tube angle, fork a2c, and fork offset, all have a larger effect on wheelbase, which is a better reflection of the "overall" handling of the bike, vs. low speed handling.
FWIW, I run my DH bike with a 63* head angle and the longest top tube I can find, but I still like my trail bikes to have ~17" chainstays.
The cost factor is basically 4-5k for 1-2."
I thought the Enduro 29 was a carbon only s-works because of the seat tube bend.
However the Specialized bike is a tank: 33lbs.
Versus this the niners 28.5lbs.
Which probabley is about 29-30lbs with pedals and a dropper.
I'm sure it's a superb bike for enduro racing and would be like a mini-dh rig. BUT I can't really see how any freeriders and anyone actually sending it would choose this bike?
Care to elaborate? What about our opinion is disagreeable?
"With a 160 millimeter stroke RockShox Pike RCT3 fork, the WFO's basic geometry lends itself well for gravity-oriented riders"
160mm?
What I was actually looking for clarification on Dave was that I didn't think there was a 160mm 29" pike but instead of jumping to conclusions about the man's lack of understanding on the topic, I politely asked him to clarify.
Understand Dave?
5k$ for a generic 150$ frame including the shock?
I pass.
