Trail grail.

FOX Racing Shox has spent the better part of the last three years completely revamping its single-crown forks. So far, this has involved everything from the chassis to the shock leg and the damper's adjustability, but the latest victim of FOX's tinkering is the axle itself. The 34 Float 29 130 3Pos-Adj FIT4 Boost Fork with 51mm of Rake adds the final touch to these upgrades by kicking the axle out by 51mm and brining it in line with the 110mm Boost spacing standard. Given the more dexterity of increased rake and the added stiffness of Boost, this version of the 34 Float comes even closer to being the holy grail of trail.

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 damper returns unchanged from last year. This includes the puffed out, 10mm shaft, which increases oil flow to the base valve, allowing the fork to ride high for quick, controlled recovery during everything from big, square hits to successive, small impacts. The 3-position Fit4 system also takes the reins from the old CTD system, changing the names from the overly-prescriptive categories of Climb, Trail, and Descend to a graduating scale covering Firm, Medium, and Open. While this change may read like an exercise in semantics, it entails a radical realignment of the 34 Float's capabilities that addresses virtually every issue we've had with CTD's damper in the past.

FIT4 also migrates the adjustable sub settings from CTD's median Trail mode to the new Open setting. Open encompasses both Descend and Trail in order to take full advantage of the fork's high ride by handling most compression duties. This makes the fork that much more relevant to five-inch situations, combining better small-bump compliance with more confident tracking across root lattices and rocky moonscapes. It doesn't wallow and handling stays on point.

The Medium setting migrates much deeper into the firm side of compression than the Trail setting did, so it'll suffice in most conditions that don't require use of the big-bottomed Open setting. The Firm setting remains self-explanatory: an XC lock-out for turning on the afterburners when terrain allows. It'll likely see much less use in the new system, but we still appreciate Firm while riding to the trailhead or transitioning on logging roads.

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 weight loss. Finally, its system of spacers lets you easily temper the air shock's volume for dialing the mid stroke.

Foxin' Awesome

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?
