Rear suspension element
Cleaning the suspension element
Do clean the suspension element, especially
the polished piston rod, if it is dirty. Remaining
dirt can damage the seals of the hydraulic sy-
stem and so shorten its life considerably.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 on page 23.
Remove the plastic spacer and pull the metal
tube off the bushing. Lubricate the bushing and
the tubes with grease. Finally remount the su-
spension element.
Hydraulic dampers are effected by wear and
tear through normal use. It depends on the
usage of the bike, the amount of dirt on it and
the maintenance and lubrication how long it
lasts.After 3000 km the damper must receive
an inspection by a trained mechanic, worn out
parts or the hydraulic cartridge can be repla-
ced then. Due to wear of the seals oil can leak
drom the damper or the internal oil can beco-
me foamy.This may lead to some noise when
the damper is working.This noise does not ef-
fect the function of the damper. Only if there
is no obvious damping after the first 5 mm of
travel, the damper should be replaced.
Please also note the maintenance instructions
of the damper manufacturer provided with
your bike.
The bushings of the rear spring element need to be lubricated
once a year.
