FOX Suspension: Technology Overview

FOX Racing Shox has become a leader in mountain bike suspension due to the cutting-edge technologies that it employs in all of its components. In this video, Outside Technician, Louis Angeley, walks you through the most noteworthy tech employed in FOX’s line of forks and shocks.

The right hand leg of your fork contains the damper. In the case of the 32 and 34 series forks, that damper will be a FIT CTD unit. “FIT” stands for FOX Isolated Technology, which is FOX’s terminology for its sealed damper. By sealing the damper oil in a bladder, FIT all but eliminates the chance of the oil becoming contaminated by air. CTD is FOX’s compression adjustment scheme, which gives you three distinct settings, Climb, Trail, and Descend, with three sub-settings in Trail mode. This enables you to fine tune your low speed compression, giving you the necessary support to keep the fork from diving, while still offering the compliance necessary to stay in control.

The left hand leg contains the fork’s air spring. FOX builds three types of air springs — one optimized for short travel applications (<130mm), one designed for long travel applications (>130mm), and a TALAS spring. “TALAS” stands for Travel Adjust Linear Air Spring, and as the name implies, it enables the user to adjust the travel in order to give you a lower ride height option for climbing and a full travel setting for descending.

Finally, there’s FOX’s renowned Kashima coat. The distinctive gold stanchion treatment yields a surface that’s both smoother and harder than standard treatments, which results in a smoother stroke. And it’s not just limited to the outside of the fork. Kashima-equipped forks also use this treatment on the air spring compression rod, further enhancing FOX’s signature smooth ride.
