Rear frame damper damping
After compressing, the suspension fork returns to
its original position. If there is a damper, it will
decelerate movement, preventing the suspension
system from springing back in an uncontrolled
manner and stopping the suspension fork
vibrating up and down.
Rebound dampers
The rear frame damper 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 deflects as soon as the wheel
touches the ground after the bump. The rear
frame damper rebounds in a controlled way, so
that the rider remains sitting in a horizontal
position when the next bump is absorbed.

A distinction is made between two types of
dampers:
• Rebound dampers,
• Compression damper
The suspension motion is predictable and
controlled. The rider is not thrown upwards or
forwards (green line).
The setting on the rebound damper depends on
the air pressure setting. A higher sag requires
lower rebound damping.
