Rear shocks
Full suspension CENTURION pedelecs
(a+b)
are not
only equipped with a suspension fork but also with
movable rear stays which are sprung and damped by
a rear shock. This feature gives you better control of
your CENTURION pedelec when riding cross-coun-
try or on rough road surfaces. The (shock) loads on
you and your CENTURION pedelec are noticeably
reduced. The rear shock normally works with an air
spring element or – less frequently – with coil springs.
Damping is usually done by oil.
To work perfectly, the rear shock has to be adjusted
to the weight of the rider, the sitting posture and the
intended use. Be sure to have this adjustment carried
out by your CENTURION dealer at the time of delivery.
For more information see the chapter “Rear shocks” in
your comprehensive original CENTURION user manual
as well as the instructions of the rear shock manufac-
turer on the enclosed CENTURION CD-ROM.

The rear shock should be set up and adjust-
ed in a way that it does not reach the end of
its travel, i.e. bottom out, unless in extreme
cases
(c)
. A spring rate which is too soft (too low air
pressure) can usually be heard or felt as a “clunk” type
noise. This noise is caused by the sudden complete
compression of the rear shock as it reaches bottom
out. If the rear shock frequently reaches bottom out, it
will sustain damage over time, and so will the frame.
G
A too strong damping of the rear frame
can result in a sluggish rebound move-
ment with a rear shock that will not recover
when exposed to a quick series of impacts. Risk of
an accident!
G
Do not turn any bolt on your rear shock,
particularly not with tools, in the vague
hope of adjusting it somehow. You could
be loosening the fastening mechanism, thus pro-
voking an accident. All manufacturers normally
mark adjustment devices with a scale or with “+”
(for stronger damping/harder suspension) and “-“
signs or with “hare” and “tortoise” icons
(d)
.
G
Full suspension frames are designed to
absorb shocks. If the rear shock is too
rigid and jammed, the terrain-induced
shocks pass directly into the frame without any
damping. This could damage the rear shock itself
as well as the frame. If your rear shock has a lock-
out mechanism, do not activate the lockout func-
tion when riding in rough terrain, but only when rid-
ing over smooth terrain (roads, field tracks).
I
Rear shock manufacturers normally in-
clude instructions with their deliveries.
You find these instructions on the en-
closed CENTURION CD-ROM. Read these careful-
ly before changing any settings or doing any main-
tenance work on your rear shock.
