Fox has completely redesigned the 40 series forks for 2021. This World Cup weapon now comes equipped with an updated version of the award-winning GRIP2 damper, an updated EVOL air spring, and a host of other radical new performance-driven features.

Factory
The Genuine Kashima Coat upper tube finish is slippery smooth and ultra-durable.

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.

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.

Bleeders
The 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.

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. Fox's 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.

GRIP2
The GRIP2 damper is the benchmark for unparalleled ride quality and ultra-precise on-the-fly adjustability. For 2021, Fox took GRIP2 to the next level by adding their patented VVC technology to the high-speed compression circuit. VVC is a proprietary variable valve control system that allows for external fine-tuning of suspension performance. GRIP2 achieves, with the twist of a knob, what typically requires the time consuming and complicated task of completely disassembling and reassembling the fork.

Float EVOL
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. The benefits of EVOL are further enhanced by our new Lower Leg channels and Bleeders, which both function to reduce air pressure captured in the lower legs, allowing the EVOL air spring to operate freely without unintended interference.
