MAINTENANCE

3.1 Service

It is essen�al to clean your fork a�er each day of riding without wai�ng. Nothing is worse for the life of your seals than dirt and
dust. The cleaning process is also extremely simple: clean the stanchions and seals with a clean rag. You can occasionally
lubricate the exterior of the seal with silicone grease.

Do not under any circumstances use degreaser. On the same note, do not power wash the forks! It will only push
the mud inside the forks and get it stuck between the stanchion and the seals.

Remember to bleed the air from your air cartridge every 5 to 10 rides depending on usage.

following measurements to ensure the fork’s func�on and your security.

The lower crown height ensures the full use of fork travel and �re
clearance. Use the following measurements to set your lower crown
height (A). This height is measured from the top of the fork leg (the
bo�om of the visible part of the dust seal) to the bo�om of the
lower crown.

The distance between the top of the upper crown and the top of the
stanchion must be between 0mm and 30mm (B). Once you have
assembled the crowns and adjusted the heights to the
measurements above, you may proceed to the �ghtening of the
bolts. USE THE FOLLOWING BOLT TORQUES.
