Air shock DT.S
WISS
XM-180
This rear shock contains pressurized air in a
main („positive“) air chamber as suspension
medium.Air shocks are lighter than steel
spring rear shocks.Another advantage is that
the spring stiffness can be easily adjusted with
an air pump: By increasing the pressure the
spring becomes harder.
The valve for the air chamber is located at the
back end of the air shock.The valve is protect-
ed by a metal valve cap.
To pump up the air shock you need a special
air pump designed for bicycle air shocks. It
must have a fitting schrader valve adaptor and
a pressure indicator.
When attaching or removing the pump
to/from the valve, you will lose some pressure
(about 0,5-1 bar).Take off the pump quickly.
Recommended pressure settings
load pressure
– 80 kg (183 lbs) 10,5 bar
–100 kg (230 lbs) 11,5 bar
–130 kg (286 lbs) 13,0 bar
Maximum allowed pressure is 18 bar.

Danger! Take care that the rear wheel or
mudguard or suspension element never hit
the frame, seat or rear rack box while the
suspension is fully compressed.
Therefore fully deflate the air shock. Have a
second person sit down on the bicycle and
make the suspension bottom out by pushing
on the seat or the rear rack.
Adjusting the damping
By adjusting the damping you can adjust the
performance of the suspension precisely to
your individual riding situation.A rough street
with many harsh bumps that occur in a row or
even cobblestones needs a low damping rate
while a road with long stretched bumps that
occur more regularly needs a stronger damp-
ing to achieve a smooth road holding.
Please note that you can seriously spoil the
riding comfort through a bad damper setting,
especially through unsystematic playing with
the knobs that may result in much to high
damper values. In the worst case the suspen-
sion element will neither compress nor de-
compress. If you are in doubt please consult
your local dealer.
A good setting for maximum comfort is
achieved when the rear wheel decompresses
completely after a shock and then oscillates
only once. In order to check the adjustment
you will need a second person that compress-
es the suspension by pushing the bicycle down
while you are sitting on the bicycle in the rid-
ing position.The other person can then ob-
serve the suspension movements.
In order to adjust the damping during decom-
pression, turn the adjustment knob on top of
the rear end of the suspension element.
If you turn the knob in direction of the „-“ you
will get less damping and thus faster decom-
pression.Turning the knob in direction of the
„+“ will give you more damping and thus slow-
er decompression.
