Smoother. Stiffer. More tunable than ever before
Completely redesigned for 2021, this World Cup weapon has its sights set on the top step. Equipped with an updated version of Fox's award-winning GRIP2 damper, an updated EVOL air spring, and a host of other radical new performance-driven features, the all-new 40 is ready to attack the track with ferocity. “Factory” says it all – feature-packed and designed to exceed the demands of Fox's Factory-level riders. What we sell is what they race. Factory Series products feature slippery smooth, ultra-durable Genuine Kashima Coat.
FLOATING AXLEFloating 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 CHANNELSAs 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. The new 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.
BLEEDERSFox's 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 ARCHStiffness-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 gravity style riding.
Modern frame designs and geometry trends require modern suspension design solutions. The arch design of the all-new 40 is designed to pair perfectly with modern Downhill bikes. Head tube profiles have grown larger and larger, and fork offsets shorter and shorter. Our new arch shape takes this need into account by jutting forward to provide ample headtube clearance at full compression. State-of-the-art computer modeling techniques helped Fox to create an organic lower leg shape that optimizes stiffness with the absolute minimal amount of material.
GRIP2A Stif Favourite, the GRIP2 damper has set the benchmark for unparalleled ride quality and ultra-precise on-the-fly adjustability. For 2021, Fox have taken 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 EVOLEVOL 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 Fox's 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.
