Rock it.

The 2017 FOX Racing Shox 34 Float 27.5 140 3Pos-Adj FIT4 Fork marks the return of 2016's much-loved updates to the trail with 140mm of plush travel for a smooth ride and impeccable control through the rough. As with the 2016 model, the fork's chassis and Float Air spring shed weight while still increasing stiffness. While this looks awesome on paper, it's even better once you get out on the trail.

The Fit4's Damper's puffed out, 10mm shaft 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 the CTD damper in the past.

Perhaps the most welcome change from earlier Fit dampers is that Fit4 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 all-mountain situations, combining better small-bump compliance with more confident tracking through rock gardens and rough terrain. 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 fire 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, a new system of spacers lets you easily temper the air shock's volume for dialing the mid stroke and ramp-up.

Best do it all fork Ever!

My Santa Cruz 5010c had one thing holding it back, the RockShox fork. I never really liked the feel of the RockShox and to add insult was the creaking noise it made as I pound down the rocky abusive trails found in the northeast. From the word go I immediately felt a difference in stiffness. The fork doesn’t bob or dive and I can trust that my front wheel is planted wherever I point it. Going up from 130mm to 140mm was a nice minor change as well. Santa Cruz should spec this fork from factory for the 5010. The fine tuning found on the factory fork is wonderful and didn’t take me long to dial it in. Did I mention the stiffness? If you have questions or want more detail give me shout. Otherwise if you are in the market for a new fork buy this one. If you ride a Pike give it away and step up to a great fork!

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?
