Understanding the Fox Float CTD Rear Shock
What is the Fox Float CTD Rear Shock?
The Fox Float CTD rear shock is a popular air-sprung suspension component designed for
mountain bikes, especially those used in trail, enduro, and all-mountain riding. The "CTD"
acronym stands for Climb, Trail, and Descend — three modes that allow riders to adapt
suspension settings according to terrain and riding needs. This shock features adjustable
rebound and compression settings, along with a user-set air pressure that determines the
shock’s sag and support characteristics. Proper pressure adjustment is critical to ensure
the shock responds appropriately, providing comfort on rough terrain and efficient power
transfer during climbs.
Why is Shock Pressure Important?
Shock pressure influences how much the suspension compresses under rider weight and
impacts how the bike handles various terrains. Incorrect pressure can lead to: - Excessive
sag (bottoming out or too soft) - Insufficient traction - Reduced control and stability -
Increased rider fatigue Conversely, optimal pressure ensures the suspension works
effectively, absorbing shocks and maintaining contact with the ground for maximum
control. ---

might require 160-180 psi
Step 3: Set the Initial Pressure
Using a shock pump, add or release air to reach the recommended pressure. Always use a
high-quality shock pump with a precise gauge for accuracy.
Step 4: Check Sag
Sag is the amount of shock travel used when you sit on the bike in a normal riding
position. To measure sag: - Place a zip tie or shock sag indicator on the stanchion - Mount
the bike in your usual riding stance - Mark the initial position of the indicator - Sit on the
bike with gear on - Measure the compression (travel used) Ideal sag for trail riding is
typically 20-30% of the shock’s total travel.
Step 5: Adjust Pressure as Needed
If the sag is too deep or shallow: - Increase pressure if sag exceeds 30% - Decrease
pressure if sag is below 20% Repeat the process until you achieve the optimal sag
percentage. ---
