9.1.9.2 Rebounding too slowly
The rear frame damper does not rebound quickly
enough after a bump has been compensated and
is not in the required initial position when the
wheel hits the next bump. The rear frame damper
remains compressed during successive bumps,
thus reducing deflection and ground contact and
increasing hardness on the next impact. The rear
wheel bounces off the second bump since the rear
frame damper does not rebound quickly enough to
make contact with the ground and return to the
initial position again. The available deflection and
traction are reduced (blue line). The rear frame damper remains in a deflected
state after contact with the first bump. When the
rear wheel hits the second bump, the saddle
follows the path of the rear wheel instead of
remaining in a horizontal position. The available
deflection and potential absorption of bumps are
reduced, which causes instability and loss of
control during successive bumps (green line).

 Turn the rebound adjuster anti-clockwise to
increase the rebound speed and improve
performance when riding over bumps.
