Rear suspension element
Changing the steel spring /DV-22)
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 130 kg (286 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 length:
DV22: 83 mm (70-90 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.
If there is a safety ring at the thread of the su-
spension element push it to the front so that
you can undo the adjustment ring completely
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.
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.

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.
