FOX suspension fork 2024 29" Float 38 F-S E-Bike 170 GRIP2 Factory Boost shiny orange Kabolt-X 15x110 mm tapered 58 HT 44 mm offset
Top fork specially optimized for e-bike use!
For long travel enduro use, the FOX 38 comes with the same superior features as its little sister, the FOX 36. The completely newly developed casting guarantees outstanding stiffness values without additional weight. Innovations such as the floating thru-axle, the optimized steerer tube, the dip tube ventilation and channels integrated into the dip tubes to improve lubrication and drain the compressed air in the casting round off the fresh cell cure. The proven Grip2 dampers and the improved FLOAT EVOL technology ensure even better responsiveness. Extremely rigid 38 mm anodized stanchions, exclusive SKF seals and the closed cartridge ensure a long service life.
Different tuning options ensure the best performance on the trail, provided they are set up correctly. And this is exactly where the problem lies - many hobby riders are overwhelmed and do not fully exploit the potential of their suspension due to incorrect settings. The result - more frustration than pleasure when biking.
The different adjustment options of the Grip2 damping ensure the best off-road performance. Ground contact is practically always guaranteed. Even in difficult passages, the fork works reliably and you never lose control of your bike.
GRIP2 damping
Fox has put all its knowledge into this damping. The various adjustment options offer the possibility of optimally adapting it to the various conditions of use.
The high- and low-speed compression and the high- and low-speed rebound can be adjusted separately. Although the setup must be carried out carefully, it offers endless riding pleasure on any surface.
With the integrated Variable Valve Control (VVC) system, the sensitivity of the high-speed rebound and high-speed compression damping is varied via a leaf spring and not by changing the preload. This results in a finely adjustable function and modification.
In addition, attention was paid to the use of low-friction and coated materials throughout the development process. This allows a very fine response and significantly increases comfort.
E-BIKE READY
Fox has adapted this fork to typical e-bike loads. The dynamic power transmission, the mostly seated riding position and higher climbing speeds place a different load on the fork than on conventional bikes. The entire chassis has been reinforced and the damper tuning optimized. According to the manufacturer, the e-bike forks are also approved for S-pedelecs up to 45 km/h.
EVOL
The enlarged negative air chamber significantly improves the response of the fork. This increases comfort because the breakaway torque has been reduced. In addition, a more linear spring characteristic curve offers better performance, especially in the middle spring travel ranges.
FLOAT AIR SPRING
The FLOAT air spring system reduces the breakaway torque and thus offers a highly sensitive fork and full comfort even with small bumps. And that for every type of rider and with a wide range of air pressures. Similar to the FLOAT suspension struts, the FLOAT suspension system is characterized by a positive and a negative air chamber, which automatically balance each other out when riding. Every rider thus enjoys the benefits of the correct, precisely balanced air pressure in both air chambers. The progression of the spring characteristic can be adjusted with our air volume spacers - allowing every rider to precisely set the characteristics of the air spring.
BLEEDERS
The dip tube bleeders allow air pressure equalization at the touch of a button. The pressure build-up in the dip tubes drastically reduces the fork performance and prevents the full suspension travel from being reached, while at the same time the sensitivity and responsiveness of the fork suffers on small bumps.
LOWER LEG CHANNELS
When a fork compresses, the air in the lower leg channels is compressed at the same time. The further the fork compresses, the more the pressure increases. This effect means that the fork responds harder and may not be able to use the full suspension travel.
The overflow channels help to solve this problem by directing the compressed air from the lower part of the fork tubes upwards, thus reducing the unintended increase in pressure. A further advantage of these channels is that the lubricating oil in the lower section of the dip tubes circulates upwards during the spring process and continuously lubricates the foam rings and the sliding bushes.
AIR VOLUME SPACERS
The FLOAT air spring on FOX forks and shocks can be fine-tuned 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.
KASHIMA COAT
The Genuine Kashima Coat coating for a butter-soft ride feel is available exclusively from FOX, the Kashima Coat logo is applied to both stanchions. The distinctive golden Genuine Kashima Coat coating offers superior overall performance and ensures minimal friction and optimum responsiveness with maximum durability.
FLOATING AXLE
Floating axles are similar to conventional thru-axle systems, but offer a significant performance advantage. The special bearing ensures perfect alignment of the fork and avoids unwanted friction caused by tension between the stanchions and lower tubes. Floating axles ensure a much more even suspension movement over the entire range of fork travel and thus improve the response behavior enormously.
ELLIPTICAL STEERER
The elliptical head tube of the 38 FOX is one of many ways to further optimize stiffness and weight, the material is only placed where it is needed to save every unnecessary gram.
