Dial in your descents.

Ramping up the sensitivity and dialed for smoother descents, the FOX Factory Series 34 Float 27.5 150 3Pos-Adj FIT4 Boost Fork is ready to take on the trail with unbeatable tracking, and power to boot. Last year we saw some reworking on the internals to elevate the quality of your ride by smoothing out trail consistencies, largely thanks to the new damper tune, and reconfigured shim stack that elevated sensitivity when you're picking your way up technical climbs, keeping your tread locked to the ground, and damping vibrations from rough terrain. Following suit, FOX revised the Float air spring with EVOL technology from their rear shocks, making it even more supple and smooth, with less force required to start inching into your suspension.

The 34 Float is an ideal match for 27.5-inch trail bikes with its 34-millimeter stanchions providing just the right amount of stiffness for precise tracking over rough trails—all while maintaining a relatively light feel for conquering brutal climbs and long stretches across the backcountry. This version gets buttery-smooth Kashima stanchions, which is a nice addition for trails with lots of roots and rocks. Boost axle spacing increases wheel stiffness out front when you're plunging into steep descents and rallying over 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. In this 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 feature that prevents damage in case you forget to unlock it on the trail.
