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 and an optional 150mm rear spacing increases rear wheel strength and stiffness. Best of all, build it how you want. Order the W.F.O. 9 with 135 or 150 rear spacing and then choose from our shock options or order without a shock.
Strengths: the frame is stiff as a 20-pound solid-steel tube frame, but without weighing 20 pounds.
a 29er with a 150mm rear spacing option. pfffft, how awesome is that?
slack front end.
certified beefcake suspension linkage.
Weaknesses: this bike should have wolves painted on it.
totally weird that it didn't come that way.
i bought the WFO in late 2011, no major breakages yet. i'm 6'4" 215 pounds -- this is the first bike in 20 years of riding mountain bikes that i haven't bought the largest frame size available. i got a large and i love the way it fits. big bike still, but feels pretty quick for such a big rid. to be sure, it's still a lot of bike to push around in tight trails, but that's the same for any 29er -- and at least this one is slack, and stiff.
The rear suspension is awesome. i had 2 vpp bikes before this one, and this suspension feels distinctly better. i've never felt pedal feedback in climbs and the progressiveness of the rear is great (i run a dhx air 5.0). i could say it climbs well (and i believe it may), but I always find that odd to say about a bike. Bikes don't climb, people do.
The WFO kicks ass. it's a bit spendy, but that just means you'll need to ride it more to get your money's worth.
Strengths: Geometry, Can go anywhere and can do anything!.....From uphill to extreme downhill.
Had the WFO9 for 2 months now. Amazing bike. It is my first 29er and from ride one the feeling was like riding it for months. Rear suspension Monarch Plus is amazing and CVA does the job. Be careful on downhill...it's too fast!!! If you are thinking of it...go for it!

Strengths: Burly and plush with the standard shock. Got mine (the old model frame+shock) from a discount for 1100$, so really worth the cash.
Weaknesses: -Steep head angle and can't fit an angleset (the old model).
-Lower linkage is really vulnerable to rocks. Not sure how many hits the linkage can take before there's any real damage.
-Routing is a bit weird for the der cables.
-Heavy.(not a big deal for me)
Awesome frame for the price I paid... Only real flaw for me is the steep head angle.

Strengths: Strong and burly. Great suspension design. Nearly zero pedal bob. Climbs well. Rolls over everything. Really fast going down. Depending on setup can be a great bike for different types of riding.
Weaknesses: If you're a weight weenie, not the bike for you. I don't care about weight though.
I'm a super clyde at 6'5" and 330lbs. This bike is amazing for a number of reasons. First, you can build it up to be a really rock solid bike so it's a great bike for larger riders. The XL frame is big and it feels like I'm in the bike, not on it. I built it to be a burly trail bike and it is a great bike for a lot of different styles of riding. Climbs well for how big it is. It's really fast going down the mountain and handles really well. I upgraded to the Fox DHX air and I although some people hate it, after I dialed it in I really like it. I can't bottom it out. Feels really buttery going down. And most importantly, there's almost no pedal bob whatsoever. It's pretty amazing as that was my biggest gripe with my old 29" GF and my 26" Stumpy fsr. The suspension design is so good for larger riders once you get the right shock and get that shock dialed in. If you want a really solid 29er trail bike that works for a lot of different conditions this bike is it.
Bike Setup: CK hubs laced to Stan's Flows, Fox 34 140 Talas, Fox DHX air, XO derailleurs, X9 shifters and crankset, 2x10 super granny 22/36 with 12-26 rear. 135 rear w/ 142 maxle kit. Avid CR w/ 203's front and back. Thomson stem and post.

Strengths: Travel, climbing, feels solid under my 250 lb clydeness Just all around fun bike.
Weaknesses: Definetly hit the crank arms more than a 26 but more a function of getting used to a new bike. Chain suck if you miss a shift, but more my fault than anything.
I got this bike as a replacement for my stolen Prophet and my first 29er, I was looking for a RIP 9 but found the WFO on CL for a very nice price, poor guy was buying a house and needed extra $ for closing (gotta love the banks last minute add ons).
Rode this bike for the first time on Kenosha Pass to Breckenridge for its real trail trial run and my first ride of the season ~30 miles. This bike climbed over wet off-camber roots like it was hard pack and flew down the rocky trail like it was on rails. The bike came with X.0 grip shifters, and that was the hardest thing for me to adjust to; I liked how fast you could shift, but it wasn't 2nd nature to me so I had some issues shifting the wrong way. Thus causing the chain suck. I changed over to triggers this winter but have yet to ride it far to see if it solved the problem, but I believe it will. I doubt I would have gotten the WFO if I hadn't gotten such a sweet deal, as it is more bike than I will use, but the weight is good for a clyde like me and the frame felt solid on the long downhills over Georgia pass into Breckenridge.

Strengths: Great climber, even better decender, very stiff frame, super plush, great in the rough technical terrain. This frame lasted a whole season and is still fine, a first for me.
Weaknesses: It is heavy but so am I
If you ride very technical terrain, up and down, and would rather go straight through than around stuff this bike is for you. It is also good if you are a larger rider looking for a AM 29er that won't flex.

This is the single most versatile bike I have ridden. It climbs very well, as good or better than any 5.5 bike I have ridden. Feels lighter than its 32lb weight. The geometry is spot on for trail riding with a 140mm Reba and short stem. I can spend all day on this bike (including epics) and love every minute of it. I may not get to the top first but I am by no means last and once at the top my friends let me go first so I don't have to pass them. I have no problems taking it to North star and keeping up with my friends on DH bikes, as long as I put on a bigger tires. I was going to get a RIP but glad I got the WFO. It is the best quiver of one bike for where I live (near Tahoe & Downieville, tons of variety). I am 6ft and 200lbs and the Lg fit me well

Strengths: Climbs great and descends better. Feels rock solid compared to similar bikes. Being 6'4" and 215lbs this bike fits me perfectly
Weaknesses: Color choices are pretty weak, Bike is not made in USA. Not a light bike and not a good choice for smaller/shorter riders
This is a great bike for tackling just about any kind of trail. It climbs and descends well and is a blast to ride. If your a taller rider I really recommend the 29ers. Overall A great bike, got a killer deal on my frame at speedgoat and if I had to do it again I would not change anything, I love this bike!

Strengths: Where to begin.. amazing climber; super-amazing descender; nimble performer in most areas compared to my 26'er. Three inches makes a HUGE difference(..that's what she said!).
HAMMER-SCHMIDT. WIDE BARS. COMMAND POST. 29" WHEELS. Oh yeah, ..and HAMMER-SCHMIDT.
Weaknesses: Aesthetically, it's not an ugly design - it's just not great-looking either. Only two colors: Vanna White or Milk Dud Brown, seriously.
Tight switchbacks can washout under bigger front wheels. Suspension setup sags under harsh V descents. Moderate chain slap.
Till now, I've never had a brand, new bike. Even as a child, I was given hand-me-downs or horse traded with kids on the block. So at nearly $100 per each year I've lived, I overreached in righting that wrong.
That said,at 6'2 and 240lbs my selection was a bit limited. I love the Ellsworth bikes; they're rolling art! Tried the Epiphany first, then the Evolve 29er. If I were 200-220lbs I'd be an Ellsworth owner today.
Either a very patient salesperson or a very slow sales day allowed me to roll multiple bikes on the streets and hills around my LBS. When I tried the WFO with the HammerSchmidt it was over. It's big and burly, not too heavy and can roll just about anything you're likely to find on the trail.

Strengths: I bought a frameset including fork, shock, front derailleur and headset.
This is a super nice frame with room for any tire and a strong, thick design. The paint resists chips better than other bikes I've had. Can use tapered or straight steer tube forks. Options for rear axle (12mm or QR). Great, great fun.
Weaknesses: This bike flaunts 5.5" of travel. It is true for the Hammerschmidt crank.
When you use the front derailleur and a conventional crank the chain stay can hit the front derailleur cage before the shock bottoms. It may not be an issue as I have yet to bomb that hard to make them touch. I'm not really sure if the entire 5.5" travel can be used with the front derailleur installed. Travel may actually be more than 5.5 with no front derailleur and the hammerschmidt or a single ring crank.
The cable routing is a little strange. It has to do with the lower dual pivot. There's so much movement it requires a bit more slack than I'm used to on a single pivot chain stay. I can deal with it.
Consider the Hammerschmidt crank if you want full use of this bikes capability.
The fat treat this frame allows is fun. This is a downhill, knock around and all mountain bike. There are better options for cross country or racing.
I took one chili because I wrote to the company about my derailleur concerns and they never replied. I would feel better if they at least told me I was nuts. Minus one chili for poor customer service.
Aside from that you'll love this bike.

This 29er is my third and I can't believe how well it handles. I was absolutely shocked at how well it climbs and thrilled with how it rolled through the descents. I was certainly taking things a whole lot faster than I ever have before.
