More sensitive than ever.

Never content with resting on previous acclaim, FOX redesigned the 34 Float 27.5 140 3Pos-Adj FIT4 Boost Fork with heightened sensitivity levels. This redesign didn't affect the legendary support and stiffness of the previous 34 Float, meaning you'll still love its precise tracking across the rough stuff. Their solution to achieving this lofty engineering feat lies in a new damper tune with a reconfigured shim stack for greater sensitivity and easier integration with add-on volume spacers. Following suit in the sensitivity department, the Float air spring now features EVOL tech (increased negative air spring volume) borrowed from FOX's rear shocks. Ultimately, this reduces the initial force required to initiate travel for a plush feel when you're smashing over small rocks and pedaling over root impediments.

The 34 Float is an ideal match for your mid-travel trail bike with its 34-millimeter stanchions providing just the right amount of stiffness for tracking across rough trails—all while maintaining a relatively light feel for conquering brutal climbs and long backcountry stretches. This version of the 34 Float enjoys the buttery-smooth sensitivity of Kashima-coated stanchions, which is a nice addition for trails with lots of root and rock impediments. Boost axle spacing increases wheel stiffness out front when you're plunging into hairy sections of trail and rallying over gnarly rock gardens.

The big story with the 34 Float lies within the Fit4 damper with 3-position Adjust. The 3-position Adjust quickly changes high and low-speed compression to suit your local terrain and riding style. In the Open setting, fluid freely flows through the low-speed compression circuit and high-speed compression shim stack for a supple, ultra-plush feel that's perfect for wicked descents and technical terrain. In the Open setting, you'll find 22 clicks of additional low-speed compression tuning for getting its feel just right. Turning the knob to Medium firms things up a bit for greater efficiency on long climbs and smooth trails. And for fire roads and asphalt roads, the Firm mode virtually locks it out, complete with a blow-off shim stack that prevents damage in case you forget to unlock it on the trail.
