Operation
6.5.15 Adjusting the
rear shock
rebound damper
Only applies to
ebikes
with this equipment
The
rear shock
rebounds at a controlled speed if
it is optimally adjusted. The rear wheel does not
bounce off rough surfaces or the ground; it stays
in contact with the ground instead
(blue
line).
The saddle is raised slightly if the bump is
compensated and gently sinks downwards when
the suspension
travels
as soon as the wheel
touches the ground after the bump. The rear
shock
damper rebounds in a controlled way, so
that the rider remains sitting in a horizontal
position when the next bump is absorbed. The
suspension motion is predictable and controlled.
The rider is not thrown upwards or forwards
(green line).
The rebound adjuster setting depends on the air
pressure setting. A higher sag requires lower
rebound damping.
Figure 100: Optimum
rear shock
riding performance
The suspension rebound speed affects the
wheel's contact with the ground, which, in turn,
has an influence on control and efficiency. The
damper should rebound fast enough to sustain
traction without producing an erratic or bumpy
sensation. If rebound damping is too tight, the
shock
is unable to rebound fast enough before
the next impact.
Adjust the rebound damping in such a way that
the
rear shock
rebounds quickly, but without
bottoming out upwards. Bottoming out refers to
when the
rear shock
rebounds too quickly and
stops moving abruptly once it has reached the full
rebound distance. You can hear and feel a slight
impact when this happens.
