Cleaning and lubricating
Do clean the suspension element, especially
the polished piston rod, if it is dirty. Remaining
dirt and sand can damage the seals of the hy-
draulic system and so shorten its life consider-
ably.When you often use dirty roads you can
protect the suspension element from dirt with
an elastic cover that you can buy at your local
dealer.
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. For that
purpose dismount the suspension element as
described under "Changing the Spring" on pa-
ge 45.
Remove the plastic spacers and pull the metal
tube out off the bushing. Lubricate the bushing
and the tubes with grease. Finally remount the
suspension element.
Move the rear swing arm down carefully. In
doing this, take care that you don't bend or
stretch any cables.
Remove the spring from the suspension ele-
ment and put in the exchange spring. Make su-
re that the new spring has the same diameter
and length as the old spring and that it lies sa-
fely on the adjustment ring.
Put back the slotted rear spring retention disc
on the piston rod. If necessary, compress the
spring a little bit with a screw driver.The
spring retention disc has to match its seating
at the rear end of the suspension element.
Secure the spring by tightening the adjustment
ring until the spring doesn't have any play any-
more. If there is a safety ring, push it back into
the slot on the thread.
Move the rear swing arm back up and connect
the rear end of the suspension element with
the rear swing arm with the bolt. Lubricate the
bolt thoroughly.
Secure the screws of the suspension element
with L
OCTITE and tighten the screw with 6-8
Nm.
In case you have a suspension element with
adjustable damping put back the adjustment
knob on the small rod, turn it so that the
screw fits exactly and noticeably to the flat
part of the rod and tighten the screw again.
After having exchanged the spring you have to
readjust the spring pre-load as described in
the chapter on "Adjusting your new bicycle"
on page 18.
Rear Suspension Element
The bushings of the rear spring element need to be lubricated
once a year.
