Spring length:
DV22: 83 mm (70-90 mm)
In order to change the spring you will have to
remove the rear screw and swivel away the
rear frame.
Hold the main frame of your bicycle in a work
stand.
If there is a safety ring at the thread of the
suspension element move it to the end so you
can unscrew the adjustment ring completely
and then turn it to the outer position at the
end. Remove the slotted spring retention disc
at the other end.
Loosen the screws of the rear suspension
element with two Allen keys and push the
screw out of the suspension element’s eye.
Danger!
If the bicycle does not stand
on the ground while undoing the screws of
the suspension element the rear swingarm
may come down uncontrolled afterwards
and hurt you seriously. In addition to this
the cables of the gear system and the
brakes may overstretch and you will have
to replace them. Ensure that the rear
swingarm comes down in a controlled and
gentle way by putting up a solid string or
zip tie between the main frame and the
rear swingarm.
Danger!
When the bicycle is standing
on the ground the frame and the swingarm
come up against each other. Please make
sure that this happens in a controlled and
gentle fashion. Put a cloth between the
contact surfaces. Otherwise, if they come
up against each other uncontrolled your
hands may get caught between main frame,
rear swingarm and suspension element and
your bicycle may be damaged
Move the rear swingarm down carefully.
While doing this, take care that you don't
bend or stretch any cables.
Remove the spring from the suspension ele-
ment and put on the replacement spring.
Make sure the new spring has the same diam-
eter and length as the old spring and that it is
supported safely by the adjustment ring.
Put back the slotted spring retention disc on
the piston rod. If necessary, compress the
spring a little bit. The spring retention disc has
to match its support at the end of the suspen-
sion element.
Secure the spring by tightening the adjustment
ring until the spring doesn't show any more
play. If there is a safety spring ring, push it
back into the slot on the thread.
Move the rear swingarm back up and connect
the rear end of the suspension element with
the rear swingarm using the bolt. Lubricate
the bolt thoroughly.
Secure the screws of the suspension element
with thread locker and tighten the screws
with 6–8 Nm.
After having exchanged the spring you have to
readjust the spring preload as described in the
chapter on "Adjusting your new bicycle" on
page 17ff.
Cleaning and lubricating
Do clean the suspension element, especially
the polished piston rod, if it is dirty. Remain-
ing dirt and sand can damage the seals of the
hydraulic system and so shorten its life con-
siderably. We recommend you to protect the
suspension element from dirt with an elastic
cover that you can buy at your local dealer
when riding on dirty roads regularly.
From time to time grease the thread for the
spring pre-load with a drop of acid-free oil.
Thus, you can always turn the adjustment ring
easily by hand. Once a year you have to
grease the pivots of the suspension element.
