Basic Overview of FOX RACING SHOX’s CTD Damper

FOX RACING SHOX‘s CTD damper can be found on their 32 and 34 line of mountain bike forks along with the FLOAT rear shock. It is intended to take the pain out of finding your ideal suspension setup with a simple 3-way adjustment. Climb, Trail, Descend. CTD.

Climb
Climb mode firms up the feel, but stops short of acting as a true lockout, given that the blow off valve allows your suspension to move under unexpected hard hits.

Trail
Click the damper into the Trail mode, and you’ll find that there’s ample low-speed compression to keep the fork riding high in the travel, while still providing the compliance you need to smooth out the ride. Trail mode has three sub-settings, which allow you to tune exactly how much feedback you want from your suspension.

Descend
Descend mode provides the lightest compression damping, and accordingly, the plushest feel.

With CTD, it’s easy to make adjustments on the fly in response to trail conditions. Or, you can always find one setting that works for you, and stick with it over the course of a ride.

My name’s Louis Angeley. I’m an Outside Technician for Fox and today I’m going to show you how to set up your CTD suspension. Your Fox fork is equipped with a CTD damper. It means Climb, Trail, Descend. It gives you five low-speed compression adjustments, three available on the fly.

We’re going to start in the Descend position. The Descend allows the damper to be most wide open, letting it react to every small bump, giving you best performance in aggressive riding. When you flip to Trail position, the Trail position is going to give you more low-speed damping. It’s going to give you a higher ride height, help with brake dive, but really perform well on false flats and your normal trail conditions. On a factory level damper, you have three different low-speed adjustments you can make in the Trail position – a soft, a medium, or firm, and those will be done by adjusting the flat black knob.

When you turn back to the Climb position, it turns the damper to the smallest flow ports inside. These flow ports are backed by a piston and a blow-off spring. This blow-off spring is going to give you a really nice strong climb position that’s going to blow off. Climb mode is not a lock-out.

Now that we’ve finished up making adjustments to the fork, we’re going to move to the rear shock. This also has CTD adjustment. Away from the valve is going to be your Descend position. It’s going to be very active and respond to every movement. As we go towards the inline position, straight down to your Trail position. That’s going to provide you with a nice low-speed platform, giving you higher ride height and more pedaling efficiency. You have the option to choose between 1, 2, and 3, a different range of low speed compression. You flip all the way over towards the valve, that’s going to be your Climb mode, your efficient pedaling mode, and not a lock-out. This climb mode is going to stay rigid while you’re pedaling and putting a force on the bike, but then blow off when you hit obstacles on the trail.
