8.2 Adjustments

8.2.1 Spring preload

Spring preload is used to set the SAG or rate of compression
when you sit on the bike and when it is being ridden.
P
• The preloading of the spring can be adjusted by turning ring
nut (P) (clockwise increases and anticlockwise decreases
the preloading).
W !
ARNING
Don't preload the spring more than 5mm (0.2") for any
reason. Preloading over the value can break the spring
preload nut or the spring clip. The spring must be
preloaded at least 1mm, if this is not done the spring
preload nut can unscrew with serious consequences to
the cyclist. If the shock absorber is still too soft after
preloading the spring to a maximum 5mm (0.2"), you will
have to change the spring with a fi rmer one. The same is
to be said for a spring with only 1mm of preload being
too fi rm, it will need to be changed to a softer one.
W !
ARNING
Replacing the spring involves removing the rear shock
from the frame, therefore this must be done by a
specialized technician.

8.2.2 Rebound adjustment

With the rebound adjuster you can control the return speed
of the rear shock after compression.
The right rebound speed setting makes the bike stable letting
it follow the variations in the terrain and any obstacles.
If the setting of the rear shock absorber is too reactive this will
make the rear suspension instable and the mountain bike will
have a tendency to snake. Too slow a setting however will
cause problems when dealing with multiple obstacles where
the suspension can't return to its fully extended position fast
enough between one obstacle and the next.
The rebound speed must be adjusted after you have adjusted
the spring preloading correctly.
The rebound speed can be adjusted with knob (R) near the
shock absorber fi xing eyelet.

•
To change the setting of the compression braking always start
from the fully closed position (adjuster fully clockwise) and
note the number of "clicks".
Don't force the adjuster knob (R) beyond its limit of travel.

R
By turning the adjuster in a clockwise direction the
hydraulic damping is increased, rendering the rear
shock slower in the rebound phase.
By turning the adjuster in a counter-clockwise direction
the hydraulic damping is decreased, rendering the rear
shock more reactive in the rebound phase.
