 Pump the suspension fork up to the desired
pressure. Never exceed the recommended
maximum air pressure. Comply with the values
of the filling pressure table.
 Remove the high-pressure pump.

 Measure the distance between the crown and
the dust wiper of the fork. This distance is the
"total deflection of the fork."
 Push the O-ring downward against the dust
wiper of the fork. If an O-ring is not available,
attach a cable tie to the stanchion temporarily.
 Put on your usual bicycling clothing, including
luggage.
 Sit on the pedelec in your usual riding position
and support yourself (e.g. against a wall or
tree).
 Get off the pedelec without allowing it to
deflect.
 Measure the distance between the dust wiper
and the O-ring or cable tie. This dimension is
the sag. The recommended sag value is
between 15% (hard) and 20% (soft) of the
"total fork deflection."

rebounds quickly, but without bottoming out
upward during testing. Bottoming out is where
the fork rebounds too quickly and stops moving
abruptly once it has reached the full rebound
distance. You will hear and feel a slight knock
when this occurs.
