The suspension elements of Fox Racing Shox are miracles of technology. There is more to them than their chic appearance would suggest. What technology is built into a Fox suspension fork or rear shock and what the technical abbreviations stand for can be found here.
Fox Racing Shox - Technologies
32 SC Chassis Design
The distinctive shape of the dip tube design is not just for looks. The Step Cast (SC) fork chassis of the 32 employs a slim design to save weight. The step in the lower part of the fork creates space for the spokes and the brake rotor at the same time. The 32 SC fork impresses with excellent handling characteristics – 32 mm stanchions and generously overlapping bushings ensure precise implementation of steering impulses.
Air Volume Spacers
The float air spring of the forks and shocks can be fine-tuned by using volume spacers to make the suspension elements more progressive or less progressive. This allows the rider to fine-tune the suspension exactly to their needs.
DPS Dual Piston System
The Float shocks with the Dual Piston System (DPS) feature three compression settings, Open, Medium and Firm, which can be adjusted on the fly. This allows the biker to adapt the chassis to changing terrain. The valve design also allows a complete lock-out - without compromising comfort, wheel control and suspension performance on rough terrain. Factory Series shocks also earn points with a low-speed compression stage in open mode that can be adjusted in 3 clicks.
EVOL (Extra Volume)
The Extra Volume Air Chamber (EVOL) decisively reduces the breakaway torque of the suspension, which guarantees even more sensitive response and maximum comfort for small bumps on the ground. The progression of the spring characteristic can be fine-tuned via air volume spacers - allowing every rider to precisely adjust the characteristics of the air spring.
FIT4 - Fox Isolated Technology
When air and oil mix, damping performance drops significantly. The insulation technology uses a membrane system that effectively prevents air and oil from mixing and ensures optimum performance even under extreme riding conditions.
The fourth generation of the patented FIT4 (FOX Isolated Technology) encapsulated cartridge system offers three on-the-fly adjustable compression positions (open, medium and firm) to adapt to terrain conditions at any time. The forks of the Factory series also have a low-speed compression adjustment with 22 clicks in open mode, so that the rider can perfectly adjust the spring behaviour to his preferences.
Float Air Spring
Patented air transfer port system: The Float air spring system reduces the breakaway torque and thus offers a highly sensitive fork and rich comfort even with small impacts. For every type of rider and at the most varied air pressure.
Similar to Float shocks, the Float suspension system is characterised by a positive and a negative air chamber, which automatically balance each other out when riding. Every rider can thus enjoy the benefits of correct, precision-balanced pressure in both air chambers. The progression of the spring can be adjusted with air volume spacers - allowing every rider to precisely set the characteristics of the air spring.
Grip
Inspired by motocross technology, the new Grip damper cartridge works with a spring-loaded, independently operating floating piston. Grip technology allows excess rear shock fluid to flow through ports at the top of the shock, ensuring even damping and increasing durability. Performance Series forks provide Open, Medium and Firm modes and an additional fine adjustment option between these three basic settings.
Kabolt axle
Inspired by racer Geoff Kabush and his collaboration with the Fox RAD programme, the Kabolt axle is now available for anyone to retrofit to all 15-QR forks. The 100 mm version is 40 g lighter than the 15QR (54% weight saving) and available in orange and black.
Kashima Coat
The distinctive gold Genuine Kashima Coat provides superior overall performance and ensures minimal friction and optimum responsiveness with maximum durability.
RVS (Rod Valve System)
Provides a seamless damping transition when dissipating small and large impacts, for faster system response, more control and less harshness.
SLS springs
The Super-Lightweight Steel (SLS) springs are lighter than titanium - and at affordable prices.
A specially-developed surface treatment and a stress-reducing manufacturing process reduces the spring's residual stress, which allows it to withstand greater loads. Each spring has also been optimised by using a smaller material diameter and fewer spring coils, allowing for a lighter product.
X2 Lever
The new 2-stage X2 open/hard mode lever available for FLOAT X2 and DHX2 shocks retains high- and low-speed compression settings, but allows you to tackle longer climbs with ease.
