Rear suspension element
Rear suspension element
Changing the steel spring (DV-22)
You can buy the spring for the rear suspension
element in different spring rates at your dealer.
We recommend the following spring rates, de-
pending on the overall weight:
up to 80 kg (176 lbs): 350 lbs./inch
up to 100 kg (220 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 rates or special light-
weight springs made of titanium.
In most cases the rate is printed onto the
spring.Pay attention to the correct imprint sin-
ce the term "B650" that sometimes occurs
does not necessarily 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 swivel 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 move it to the end so you
can unscrew the adjustment ring completely
and then turn it to the outer position at the
end. Remove the slotted spring retention disc
at the other end.
Loosen the screws of the rear suspension ele-
ment with two Allen keys and push the screw
out of the suspension element’s eye.
Move the rear swing arm down carefully.While
doing this, take care that you don't bend or
stretch any cables.
Remove the spring from the suspension ele-
ment and put on the replacement spring. Make
sure the new spring has the same diameter
and length as the old spring and that it is sup-
ported safely by the adjustment ring.
Put back the slotted spring retention disc on
the piston rod. If necessary, compress the
spring a little bit.The spring retention disc has
to match its support at the end of the suspen-
sion 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 will have to replace
them. Ensure that the rear swing arm comes
down in a controlled and gentle way by put-
ting up a solid string or zip tie between 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 sur-
faces. Otherwise, if they come up against
each other uncontrolled your hands may get
caught between main frame, rear swing arm
and suspension element and your bicycle
may be damaged.
