Slopestyle riders and dirt jumpers: Fox's 831 fork is made specifically for you. It's tuned to smooth bumpy run-ins and soak up hard landings while minimizing pedal bob when you're sprinting out of the gate. Even if you happen to overshoot the tranny to flat, the 831 has plenty of damping to absorb big hits. Berm-carving stiffness is built in, because the brace and crown are the same ones on Fox's longer travel forks, and the 15mm thru-axle ensures your front wheel goes where you point it. To custom tune the 831, there's the CTD damper to suit your riding style and the trail at that exact moment. And, the Kashima-coated stanchions laugh at stiction and the FIT damper keeps air and oil separate to ensure smooth suspension all the time.

Fox's gold-colored Kashima coat.

For the best suspension yet, Fox has brought Miyaki Company of Japan’s legendary Kashima Coat to its fork stanchions. You can recognize it by the unique gold color. This coating, which is four times harder than hard- anodized aluminum, made its name in car and motorcycle suspensions and drivetrains, and now you can enjoy all its amazing benefits. These include super low friction, excellent abrasion resistance and durability, and significantly better lubrication characteristics. In short, this fork is way more reactive, soaks up even tiny bumps and lasts longer with less maintenance, too.


Fox's 15QR thru-axle system drastically increases the fork's stiffness- to-weight ratio, is lighter than a 20mm thru-axle, and way stiffer than a standard dropout and quick release. Wheel installation and removal is tool- free, fast, and easy.
