Construction & Measurements:
1.5" Tapered Aluminum Steerer
Kashima Coated Stanchions: The smoothest of the smooth, plus it looks cooler. The gold Kashima coating has become synonymous with friction-free suspension actuation, and it's only available on Fox Factory components.
New Lower Leg Channels: As a fork compresses, the air volume within the lower legs decreases, increasing air pressure. The more the fork compresses, the more pressure increases. This effect can have the unintended consequence of preventing full travel from being achieved. Fox's lower leg channels help alleviate this issue by dramatically increasing air volume within the lower legs and thereby reducing the amount of additional unintended pressure ramping. Another benefit of these channels is that lower leg bath oil is circulated to the upper reaches of the lower legs, continuously lubricating the foam rings and bushings as the fork compresses and extends through its travel.
New Lower Leg Arch: Stiffness-to-weight is the ultimate metric for bicycle design. Engineers invest countless hours poring over every ounce of material in an effort to optimize this critical ratio. Our all-new lower leg design pulls out all the stops, shaving every possible gram while making sure not to compromise stiffness or strength requirements of modern enduro and gravity style riding.
Features:
Floating Axle: Floating axles might look similar to other axles, but in fact they offer a distinct performance advantage due to their unique ability to match the exact width of the fork’s wheel mounting surface precisely to the front hub flange spacing, thus creating perfect chassis alignment and eliminating unwanted friction between the upper and lower fork legs. Floating axles provide much smoother suspension movement throughout the entire range of the fork’s travel, notably improving sensitivity and overall ride quality.
FLOAT EVOL Air Spring: EVOL technology increases negative air spring volume, optimizing small bump sensitivity. EVOL’s linear spring curve delivers plushness off the top, extra mid-stroke support, and more tunable bottom-out progression.
Rotor Size: 180 Direct Post Mount, Up to 230 Compatible
Adjustments:
FIT4 Damper: In its fourth generation, this patented closed cartridge system provides 3 on-the-fly compression damping positions--open, medium, and firm--to adapt to varying trail conditions. This Factory Series model also has 22 clicks of low-speed compression in Open mode, along with 10 clicks of low-speed rebound, all of this is on top of initial air spring pressure and volume spacer compatibility, making for a very tunable setup.
Pressure Bleeders: Lower leg bleeders allow for atmospheric pressure equalization at the simple press of a button. Pressure build-up in the lower legs dramatically decreases fork performance, preventing full travel from being achieved, and diminishing small bump sensitivity and responsiveness.
