Rear suspension element
Changing the spring
You can buy the spring for the rear suspension
element in different spring stiffnesses from
your dealer.
We recommend the following spring stiffnes-
ses, depending on the overall weight:
up to 80 kg (183 lbs): 350 lbs./inch
up to 100 kg (230 lbs): 450 lbs./inch
up to 120 kg (275 lbs): 550 lbs./inch
In addition to this your dealer can also use
springs with other spring stiffnesses or special
lightweight springs made of titanium.
In most cases the stiffness is printed onto the
spring.Take care to read the imprint carefully,
since the term "B650" that sometimes occurs
does not mean 650 lbs./inch!
Spring lengths:
DV22: 83 mm (70-90 mm)
ST8ARC: 70 mm (65-76 mm)
In order to change the spring you will have to
remove the rear screw and swing away the re-
ar frame.
Hold the main frame of your bicycle in a work
stand.
In case you have a suspension element with
adjustable damping first remove the rear ad-
justment knob for the damping control by un-
doing the small screw at the side with an Allen
key and by then pulling of the knob.
If there is a safety ring at the thread of the
suspension element push it to the front so
that you can undo the adjustment ring comple-
tely and then turn it to the utmost position at
the front. Remove the slotted spring retention
disc at the rear end.
Undo the screws of the rear suspension ele-
ment with two Allen keys and push the screw
out of the suspension element eye.

Danger! If the bicycle does not stand on
the ground while undoing the screws of the
suspension element the rear swing arm may
come down uncontrolled afterwards and
hurt you seriously. In addition to this the ca-
bles of the gear system and the brakes may
overstretch and you would have to replace
them. Ensure that the rear swing arm comes
down in a controlled and gentle fashion by
putting up a solid string or cable tie bet-
ween the main frame and the rear swing
arm.
Danger! When the bicycle is standing on
the ground the frame and the swing arm co-
me up against each other. Please make sure
that this happens in a controlled and gentle
fashion. Put a cloth between the contact po-
ints. Otherwise, if they come up against each
other uncontrolled your hands may get
caught between main frame, rear arm swing
and suspension element and your bicycle
may be damaged.
