FOX - Redefine Your Limits
CTD is our integrated ride dynamics system that makes it easy to set up your fork, shock, and seatpost to work together for unprecedented performance in all types of terrain.
Select one of three modes on the fly—Climb, Trail, or Descend—to match whatever the trail throws at you.
CTD Bike Activate each grey icon to learn how CTD works across the bike.

Climb ModeClimb


Extends to highest travel setting for full leg extension and maximum climbing power.

Fork & Shock

The firmest low-speed compression setting is activated for maximum pedaling efficiency.

The Climb mode setting of each fork is optimized for its specific travel — the shorter the travel, the firmer the ride tune and feel.

Trail ModeTrail


Drops to the middle height position for a lower center of gravity and the perfect balance of pedaling efficiency and control on roots, rocks and other trail obstacles.

Fork & Shock

Moderate low-speed compression setting is activated for an optimal blend of pedaling efficiency and bike control on variable terrain. Factory Series products offer three levels of Trail-mode adjust.

Descend ModeDescend


Drops to the lowest position so you can get your weight back and control your bike on the steepest, most technical descents.

Fork & Shock

Low-speed compression setting activates to full-open for maximum control and plush performance on steep, aggressive descents.
