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.

The all-new 36 and 38 come equipped with a new quick-release lever operated patent-pending floating axle system, combining the benefit of a floating axle with the ease of a tool-free quick-release. With this system, spacing is locked in via a floating sleeve, allowing repeated front wheel removal and reinstallation while maintaining perfect fork alignment. Floating sleeve positioning comes preset from the factory so if you are unsure of how to operate the floating axle system or simply don’t want to bother with it, you can just install the front wheel and get on with your ride. Available optionally is the new Kabolt-X, a lightweight bolt-on floating axle exclusively for the all-new 36 and 38 that not only shaves grams but also increases torsional stiffness via its sleeveless, single-sided pinch bolt design. Chassis alignment must be reset each time the front wheel is removed and reinstalled on both the Kabolt-X and 40 floating axles, but the end result is the same – perfect alignment and perfect performance.

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. Our 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.

BLEEDERS

Our 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. 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. 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. 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 us to create an organic lower leg shape that optimizes stiffness with the absolute minimal amount of material.

GRIP

Grip cartridge, inspired by the hydraulics operating motorcycle forks and based on a FIT sealed cartridge system that’s already been adopted on top end forks for several years and now in its fourth version. Unlike normal FIT cartridges from FOX, the FIT Grip has been simplified with the adoption of a spring to control the internal floating piston in the cartridge which handles compression damping. Inspired by moto fork damping systems, FOX’s new GRIP damper uses our FIT sealed cartridge technology combined with a coil-sprung, internal floating piston. The system allows excess oil to purge through a specially designed port at the top of the damper to maintain consistent damping and increase durability. FIT GRIP dampers are used in Performance and Rhythm Series forks, bringing a new level of ride quality and adjustment to those price points. Performance Series forks provide Open, Medium, and Firm modes with additional micro-adjust between settings, giving riders added control to fine-tune their damping needs. Rhythm Series forks offer 2-position sweep adjust, giving riders a wider range of damping adjustment and performance never seen before at this level.

FIT4 kartuša

For model year 2020, Fox is making an update to their FIT4 Damper by equipping them with an 8mm damper shaft, a new bladder construction, and a reconfigured shim stack. The reason for the damper shaft change is to create a system with a little less damping, allowing the rider to experience a little more sensitivity on the trail. Low speed compression can still be dialed in so that you can maintain an aggressive riding style without getting sucked down into the fork’s travel. As far as rebound goes, the newly reconfigured shim stack fits in line with Fox’s latest tuning improvements. Additionally, the new assembly weighs less, giving you 35 grams of weight savings. This update will apply to all 2020 Fox 32, 34, and 36 non Step-Cast forks sporting FIT4 dampers. Those of you lucky enough to own model year 2019 Step Cast forks already have this sweet upgrade. Just in case you’re unaware, the FIT4 damper system is a closed cartridge with three position damping settings: Open, Medium, and Firm. Factory Series forks allow extra adjustability in the Open position with 22 clicks of low-speed compression, giving you tons of options for varying trail conditions without the millions of knobs that some suspension products come with.

GRIP2

Our GRIP2 damper is the benchmark for unparalleled ride quality and ultra-precise on-the-fly adjustability. For 2021, we’ve taken GRIP2 to the next level by adding our 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.
