CTD is Fox's new suspension system that takes the guesswork out of getting your fork and shock set up to work in harmony. CTD is short for Climb, Trail, and Descend modes. These terrain modes are identical between your fork and shock so you can match your suspension settings on-the-fly to varying conditions and riding styles.The terrain mode system makes it easy to experiment with different settings and easily get back to your starting point with confidence. If you like running one setting all of the time, set the fork and shock to Trail mode and go. Riders can use these terrain modes as often as they please or just leave the adjuster in Trail mode for all around performance. Riders do not necessarily have to exactly match the CTD adjuster to the terrain features by name.
In this video, Fox's technical service rep Nick Delauder gives us the rundown on CTD, and a few tips for riding the system the right way.
