The inner fork steerer tube is tightly fitted
and glued in the fork crown, never try to tear
this connection apart or to change the tube.
Never add threads to the steerer tube –
danger of breaking! The hydraulic damping
cartridge is pressurized and must not be
opened. In case of damage the whole car-
tridge has to be replaced.
Danger!
After you have removed the
adjustment screw (5) you'll see a small
hex-headed screw in the piston rod of the
damper: never undo this screw. It is under
pressure. If this screw is undone too far it
can damage the damper.
Before every ride check the suspension fork
for signs of damage, deformation or corro-
sion. If this is the case don't use your bicycle
anymore. Ask your local dealer for service.
Exchanging springs
Turn the adjustment knob for the pre-load on
the adjustment unit (9) counter-clockwise as
far as possible. This causes the spring to relax.
Place a matching spanner or an adjustable
wrench on the two parallel surfaces of the
pre-load adjustment unit. Then remove the
entire unit by turning it counter-clockwise.
Carefully remove the springs with one finger
or the head of a spoke from the fork.
Alternatively put your bicycle upside down
and catch the springs when they fall down.
Exchange the springs, lightly grease all parts
and assemble the fork again in reverse order.
After having finished the assembly please
check if the fork works properly by com-
pressing it several times manually.
