Adjusting The Steel Suspension Fork Negative Deflection; Adjusting The Air Suspension Fork - Bosch BULLS Twenty 6 EVO Translation Of The Original Operating Instructions

6.5.6.2 Adjusting the steel suspension fork
negative deflection
Only applies to pedelecs with this equipment
You can adjust the tensioning in the fork spring to
the rider's weight and their preferred riding style.
This reduces the negative deflection in the fork.
Figure 58: Negative deflection setting wheel on the
suspension fork crown
1 You will find the negative deflection setting
wheel beneath the plastic cover on the crown.
Remove the plastic cover.
Turn the negative deflection setting wheel in a
clockwise direction to increase the spring pre-
tensioning.
Turn the negative deflection setting wheel in
an anti-clockwise direction to decrease the
spring pre-tensioning.
 You will have made the ideal setting when the
shock absorber deflects 3 mm when subject to
the rider's weight.
3 Replace the plastic cover on the crown after
making the setting.

 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
