The Fox 40 Shock Absorber Forks upgrade for a Sur Ron or Talaria is simply the best there is.

Equipped with an updated version of their award-winning GRIP2 damper, an updated EVOL air spring, and a host of other radical new performance-driven features, the all-new Fox 40 Forks are ready to attack the track with ferocity.

The Fox 40 GRIP2 damper is the benchmark for unparalleled ride quality and ultra-precise adjustability. GRIP2 includes the patented Variable Valve Control (VVC) technology which 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.

High-speed compression (w/VVC) 8 clicks
Low-speed compression 16 clicks
High-speed rebound (w/VVC) 8 clicks
Low-speed rebound 16 clicks



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.

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. The 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.

The lower leg bleeders allow for atmospheric pressure equalisation 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.

Stiffness-to-weight is the ultimate metric for bicycle design. Engineers invest countless hours poring over every ounce of material in an effort to optimise this critical ratio. The 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.

Modern frame designs and geometry trends require modern suspension design solutions. The arch design of the all-new 36, 38, and 40 is designed to pair perfectly with modern Enduro and Downhill bikes. Head tube profiles have grown larger and larger, and fork offsets shorter and shorter. The new arch shape takes this need into account by jutting forward to provide ample head-tube clearance at full compression. State-of-the-art computer modelling techniques helped us to create an organic lower leg shape that optimises stiffness with the absolute minimal amount of material.

EVOL technology increases negative air spring volume, optimising small bump sensitivity. EVOL’s linear spring curve delivers plushness off the top, extra mid-stroke support, and more tuneable bottom-out progression.

The benefits of EVOL are further enhanced by the 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.
