Adjusting The Air Suspension Fork Negative Deflection; Adjusting The Air Suspension Fork Rebound - Bosch Kiox Original Operating Instructions

6.5.5.3 Adjusting the air suspension fork
negative deflection
 The air valve is located beneath the valve cap
on the crown of the left-hand shock absorber.
Unscrew the valve cap.

1 Attach a high-pressure damper pump to the air
valve.
2 Pump air suspension fork to the required
pressure. Observe the levels in the Suntour
filling pressure table. Never exceed the
recommended maximum air pressure.

3 Detach high-pressure damper pump.
4 Measure the distance between the crown and
the dust seal. This distance is total deflection
of the fork.
5 Push a temporarily attached cable tie
downward against the dust seal.
6 Put on your normal cycling clothing, including
luggage.
7 Sit on the pedelec in your usual riding position
and support yourself against an object, such as
a wall or tree.

8 Get off the pedelec without allowing it to
deflect.
9 Measure distance between the dust seal and
the cable tie.
 This measurement is the negative deflection.
The recommended value is between 15%
(hard) and 30% (soft) of the total fork
deflection.
10 Increase or reduce air pressure until you have
reached the desired negative deflection.
 If the negative deflection is correct, turn the
valve cap in a clockwise direction.
 If you are unable to achieve the desired
negative deflection, an internal adjustment
may be needed. Contact your specialist dealer.
6.5.5.4 Adjusting the air suspension fork
rebound
The rebound setting depends on the negative
deflection setting: A higher negative deflection
requires a lower rebound setting.
1 Turn the Suntour rebound screw in a
clockwise direction to the closed position until
it stops.

2 Turn the Suntour rebound screw slightly in an
anti-clockwise direction.
3 Adjust 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.
