Conventional wisdom suggests 29ers are only viable at high speed on smooth hardpack. FOX Racing Shox doesn’t give a damn. The brand's 34 Float 29 140 3Pos-Adj FIT4 Fork with 51mm Rake combines five inches of generous travel, a high-riding tendency, and an offset axle to aid in low-speed maneuvers — in short, all of the benefits of wagon wheels' high angle of attack and none of the downsides that relegated earlier generations to the XC life.

A fork with 51mm of rake decreases the bike's trail, which results in less "dead" space between the steering axis and the hub. The design is an attempt to offset the floppy, low-speed steering issues that arise from the longer trails produced by taller wheels and slack geometries, so handling stays 26er-sharp at all speeds, whether climbing, ripping, or navigating switchbacks and tricky terrain.

The Fit4 returns unchanged for 2017, so it still toggles between a menu of Firm, Medium, and Open settings. The Open setting encompasses the range that FOX's old model, CTD, divided between Descend and Trail. We tend to spend most of our time in Open in order to take full advantage of the fork's high-riding tendencies, combining better small-bump compliance with more confident tracking across successive impacts and rough terrain. The Medium setting is much firmer now, handling duties ranging from rooty trails to climbing, and the Firm setting is now largely relegated to fast hardpack and fire road transitions.

FOX's tinkering wasn't just confined to the damper, though, as the Float air spring now omits the negative coil in favor of a self-equalizing air assembly. This is similar to the air spring chamber system that made the re-worked 36 series such a success, and its omission of a steel coil is a key contributor to the overall claimed weight loss of 297 grams — quite a feat when you consider that the latest 34 Float 29 also retains the 2016 model's gains in stiffness.

Light Strong, and PLUSH

    I love this fork. Fox hits it out of the ballpark on plushness, and it is very smooth over small bumps. Plus, I love the Orange stickers.

    Will a Minion DHF 2.5 fit? Cant find max tire size here on on Fox

    • Familiarity: I've used it once or twice and have initial impressions

    Very light, strong, i think its durability is the key I purchased it. I have it for a few weeks only. But i could feel the big difference over my old forks rockshox revelation. Easy to adjust. The rake they mean here is turning, and it did feel easy to turn your wheels on tight turns. Feels like 650b. Great!!!

    Foxin' Awesome

    • Familiarity: I've put it through the wringer

    This fork… holy cow. It belongs on every mid travel bike. I know, I know, blanket statement, but I think the fork is THAT good. I used to be nervous of square edges, rock gardens, roots, ruts, and plain old crap, this thing just soaks it up. “Confidence inspiring” doesn’t do it justice.

    This fork tracks where I want it to go, doesn’t feel like dead weight, and is supple. I truly feel that at every moment, this fork is setting me up to literally overcome my obstacle.

    It's also so light for how capable it is! Performance/weight ratio is spot on with this guy, it doesn't mind big climbs.

    With the new FIT4 damper, this fork has truly useful Compression modes and is simple an intuitive to adjust and tune. Unless you really like to geek out on suspension (I’m guilty!) the LSC, Rebound, and Air Volume adjustments are all you’ll need and are super easy to get dialed in.

    And yes, I’ve ridden on a Pike. And yes I’d take the Fox. Every time.

    Building a new bike? Upgrading the current whip? Give me a shout and I’ll make sure you get the perfect build.

    Even if you’re not ready to pull the trigger, reach out if you have questions like:
    - What do all the knobs and dials do?
    - How do I set my suspension for me?
    - Which fork is right for my bike?

    Ben, thanks for taking the call and reviewing this fork with me!
