Operation
10 Measure the distance between the dust wiper
and the O-ring or cable tie.
This measurement is the negative deflection.
The recommended value is between 15%
(hard) and 20% (soft) of the total fork
deflection.
11 Increase or reduce the air pressure until you
have reached the desired negative deflection.
If the negative deflection is correct, turn the
blue valve cap in a clockwise direction.
6.5.7.2 Adjusting the rebound
The rebound defines the speed at which the fork
rebounds after being loaded. The rebound setting
depends on the air pressure setting. A higher
negative deflection requires a lower rebound
setting.
1Turn the FOX rebound adjuster in a clockwise
direction to the closed position until it stops.
Figure 73: FOX rebound adjuster (1) on the fork end
2Turn the FOX rebound adjuster slightly in an
anti-clockwise direction.
3Adjust the rebound in such a way that the fork
rebounds quickly, but without bottoming out
upward. Bottoming out refers to when the fork
rebounds too quickly and stops moving
abruptly once it has reached the full rebound
distance. You can hear and feel a slight impact
when this happens.
6.5.8 Setting the Suntour rear frame
damper
Only applies to pedelecs with this equipment
6.5.8.1 Adjusting the negative deflection
Negative deflection depends on the rider's weight
and sitting position. The recommended negative
deflection should be between 25% and 30% of the
total rear frame damper deflection, depending on
preferences and pedelec use.
When adjusting the negative deflection, ensure
that the compression adjuster is in an open
position, i.e. the lockout lever is in the OPEN
position.
1Remove the valve cap from the air valve.
2Attach a high-pressure damper pump.
3Adjust the rear frame damper air pressure to
the rider's weight.
4Detach high-pressure damper pump.
5Measure the distance between the air chamber
seal and the end of the rear frame damper.
This gap is the total rear frame damper
deflection.
6Put on your normal cycling clothing, including
luggage.
7Sit on the pedelec in your usual riding position
and support yourself against an object, such as
a wall or tree.
8Push the O-ring downwards against the air
chamber seal.
9Get off the pedelec without the suspension fork
deflecting.
Measure the distance between the air chamber
seal and the O-ring. This measurement is the
negative deflection. The recommended value
is between 25% (hard) and 30% (soft) of the
total rear frame damper deflection.
If you are unable to achieve the desired negative
deflection, internal settings may need to be
changed. Contact your specialist dealer.

Notice
If the air pressure in the rear frame damper is
exceeded or undershot, the damper can be
permanently damaged.
Do not exceed the maximum air pressure of
300 psi (20 bar).
