Operation Manual
Cycle Suspension
95
Rear suspension, which is installed centrally
between the front and rear frame, absorbs
impacts to the rear wheel and increases
comfort as well as safety when riding over
uneven ground. The rear suspension must
be tuned to the intended use and the rider’s
weight. Rear suspension increases comfort
when riding over uneven ground.
x If your cycle is equipped with
adjustable rear suspension, refer to the
adjustment information enclosed by the
manufacturer.
12.2.2 Adjustments
The following adjustment options are generally available:
– Compression and rebound
– Sag (compression under body weight)
– Lockout (suspension locking feature)
12.2.2.1 Compression and rebound
Adjusting the compression and rebound influences the damping or response behaviour
of the suspension fork or rear suspension. The ratio between compression and rebound
is crucial. Depending on the cycle model, the suspension may only be equipped for
rebound adjustment. The ratio between compression and rebound is determined by the
condition of the road. A correctly adjusted ratio ensures optimum contact between the
wheels and the ground.
x Have the compression and rebound adjusted by your dealer.
12.2.2.2 Sag
Sag is the amount of compression caused by the rider’s body weight. Depending on the
model of the suspension fork or rear suspension, and depending on the intended use,
the sag is adjusted to a value between 15 % and 40 % of the total suspension travel.
Sag is influenced by the spring preload. When the sag is optimally adjusted, the
suspension will compress by 15 % to 40 % of its travel when the rider sits on the cycle.
The sag is determined by the spring preload or by the adjustable air pressure in the
suspension fork or damper. The spring preload or the air pressure therefore determine
the stiffness of the suspension and whether the chassis is hard or soft.
x Have your dealer adjust the suspension fork or rear suspension to your body
weight and riding style.
