•
Consult your specialist dealer for information about suitable
maintenance and lubrication products for the suspension fork.
•
Compress the suspension fork in and out five times. After-
wards, wipe up any excess lubricant with a clean cloth.
•
If you hear unusual sounds when compressing and decom-
pressing the fork or if the suspension fork gives way with-
out any resistance, get your specialist dealer to check your
suspension fork.

Sag
Sag refers to the compression which takes place simply as a result
of the rider’s bodyweight. Depending on the model of the suspen-
sion fork, the sag is set at a value of between 15% and 30% of the
total suspension travel.
The sag setting does not affect the spring stiffness. The sag setting
affects the spring pre-load. If the sag is optimally adjusted, the
suspension will compress by just a few millimetres when you sit
on the bicycle.
Expert knowledge is required to adjust the sag setting, especially
when the bicycle features several different suspension elements.
note:
To ensure optimally adjusted sag, your specialist dealer may
install stiffer or softer springs in the suspension.
12.9.1.3
Lock-out
The “lock-out” function blocks the suspension fork. This can reduce
the build-up of vibrations and dipping of the suspension fork, e.g.
if the suspension dips down when pedalling with greater force.
12.9.1.4
Rebound and compression damping
The settings of the rebound and compression damping affects the
cushioning effect, or responsiveness, of the suspension system.
The key factor here is the ratio between the rebound and com-
pression damping. Many models are therefore only fitted with one
setting for rebound damping. The ratio between the rebound and
compression damping is determined by the road conditions. A cor-
rectly adjust ratio ensures optimum contact between the wheels
and the ground.
12.9.1.5
operation
The operation of the suspension fork depends on your suspension
fork type.
•
If your suspension fork is fitted with other controls or additional
controls than those listed below, you should ask your specialist
dealer to explain how to operate the suspension fork or read
the manufacturer’s documentation.
