Setting
the air pressure
The suspension fork must be filled with air through the air valve. Use only suitable
high pressure pumps, e.g. the ACROS SP-01.
Remove the air topcap. Thread the pumps valve onto the air valve until pressure
registers on the pump gauge (approx. 6 turns).
To increase the pressure stroke the pump a few cycles.
To dicrease the pressure press the black bleed-valve.
Never ride without air pressure, as otherwise the fork bottoms. You should set the
air pressure according to your weight and riding style. Depending on cyclist weight
and the desired progression characteristics, 10 bar should not be exceeded. It
should also be borne in mind that the possible travel of the fork is reduced if there
is too much fluid, as the fluid cannot be compressed.
The design of the system means that the setting of the air pressure is directly dependent on the fluid volume. For this reason, pay particular attention to the following
sections.
The adjacent diagram shows how the air and fluid column works as well as their
dependency. This dependency means that even small changes to the fluid volume
result in corresponding changes. The size of the fluid column determines the size of
the air volume. Moreover, the fluid is pushed upwards by the plunger on compression. It can only flow back through the adjustable nozzle, leading to the damping.
With these two variables, air pressure and fluid volume, you can adjust the setup of
the fork to fit your personal needs perfectly. You should take account of the fact that
the negative travel also changes the level of the fluid column. The values provided
in this manual are guide values.
At the upper end of the right upper tube is a setting wheel that can be used at any
time to adapt the desired damping (rebound) to the given needs and changed
conditions while you are riding the bike. Using the markings, the wheel with the
arrow can be turned to the desired position. Turning 180° changes the damping
from minimum to maximum. The setting wheel has an endless thread (no stop
point) and should always be turned clockwise. On some newer models, the crown
itself is practically a stop point.
Caution:
As the fork does not retract quickly enough in the case of strong rebound damping, it quickly begins to jump in the event of irregularities in rapid succession.
This can lead to your losing control of the bike and possibly suffering severe or
fatal injuries.
The air pressure in the upper tube must not exceed 10 bar. Always ensure that the
upper and lower securing rings are correctly seated. Never ride the bike without
fluid, as this significantly impairs the properties of the suspension fork.
