4.1 AIR SPRING
4.1.1 ADJUSTMENT OF THE SAG
The SAG is the amount of travel of which the fork will be compressed by the weight of the rider with full equipment. If the
SAG is correctly adjusted, the front wheel can better follow the ground during the ride.
To set up the SAG, you will have to adjust the air pressure in your fork. You may eventually need the help of another person.
• To measure the SAG you have to deactivate the function of your fork:
• EX-Models: deactivate the Launch control
• XM-Models: put the Single Shot or Twin Shot on position 1
• Push the o-ring on the right stanchion to the bottom, until it touches the wiper seal
• Sit with full equipment (backpack, helmet, shoes...) on the bike as you would sit during the ride. The fork goes down
because of your own weight.
• Step down of your bike and measure the distance between o-ring and wiper seal. This measurement is called SAG. The SAG
should be between 15% and 25% of the full travel and can be adjusted depending on the riding style and use.

4.1.2 ADJUSTMENT OF THE AIR PRESSURE
CAUTION
Do not use the fork while the shock pump is mounted. This may cause the shock pump to touch the frame and the valve-
thread will break off.
INFORMATION
Only use a suitable shock pump to adjust the air pressure. We suggest to use the DT Swiss shock pump
(Art. Nr. FXTXXX0S000040223S)
In all DT Swiss fork models, the air spring is located in the left stanchion. By adjusting the air pressure, the spring rate will be
affected. The higher the air pressure, the harder the spring.
The air chamber is filled with a small amount of lubricating oil. Make sure that the valve is upwards during inflation or defla-
tion.
Adjustment is possible by changing the air pressure. Adjusting the air pressure to the weight of the rider can slightly change
the total length of the fork.
• Position the fork resp. the bicycle that the valve on the left upper stanchion is upward.
• Remove the valve cap from the valve-housing.
• Mount a suitable shock pump on to the valve-housing.
• Adjust the air pressure by in- or deflating.
• Screw the valve cap on to the valve-housing.
