On some forks, recommended air pressure val-
ues are stated.
1. Other air pressures or settings may
be re uired. Example Different riding
styles and uses call for a different air
pressure and a different le el of sag.
Accordingly, this adjustment proce-
dure serves only as a starting point.
2. The valve cap on the suspension ele-
ment must always be fitted when rid
-
ing, to prevent any dirt from entering
the valve.
Push the 0-ring for the suspension travel indicator
against the air chamber/the forks lower legs.
Carefully position yourself centrally on the bike
and then dismount.
Important: if you place too great a load on the bike
when getting on and off, you will obtain incorrect
measurement values.
Check the position of the 0-ring on the suspen-
sion element’s housing. Check that sag is in the
25 range.
If sag is lower than the value recommended by
the bicycle manufacturer, i.e. the suspension
element is compressed by less than 25 , you
should reduce the air pressure. If sag is greater
than the value recommended by the bicycle man-
ufacturer, you should increase the air pressure.
The air pressure in the rear shock absorber must
not exceed the maximum alue stated in the as
-
sociated operating instructions. Refit the air cap.
Adjustable rebound
The rebound governs the speed at which the
suspension element is fully extended again af
-
ter compression. The suspension elements are
provided with a red rebound adjuster, which is
used to set the desired rebound. The suspension
element springs back out most rapidly when the
adjuster knob is turned out anti-clockwise to the
end of its travel. It springs back out most slowly
when the knob is turned in clockwise to the end
of its travel.
Setting rebound
The starting point for setting rebound can be de-
termined at a kerb.
Before proceeding to set suspension re-
bound, you must first ha e set the sag in
the suspension.

The description can be used for both the sus-
pension fork and the rear shock absorber. If an
instruction applies for only one of the two compo-
nents, this is noted.
In this section, the air springs’ basic tuning will
be described. There are two tuning options – the
spring rate of the suspension and the rebound of
the shock absorber.
Contact a FLYER dealer who will inform
you about the correct settings for the
suspension elements. A table showing all
of the setting recommendations for the
coil springs can be found on this website:

Sag
The suspension elements are provided
with a lockout to be used when required
on steep asphalt rises to suppress
spring compression and bobbing up and
down. The following adjustment opera-
tions can only be undertaken with the
lockout open.
“Sag” is the distance by which the suspension el-
ement is compressed when the rider is positioned
centrally on the bike. The sag preloads the sus-
pension element and keeps the rear wheel on the
ground under light load and over slight bumps.
This improves grip on the ground and traction on
rough terrain.
As a rule, sag accounts for 25 of the a ailable
overall suspension travel.
To set the sag for your suspension element prop-
erly, you must first set the suspension hardness/
air pressure. Adjusting the air pressure also
changes the o erall stiffness of the suspension
element. The more you pump up the suspen-
sion element the harder it becomes. To set the
suspension element optimally between the sag
recommended by the manufacturer and the
desired stiffness, obser e the following setting
instructions:
Adjusting sag
Ensure that the pressure levels at the fork and
shock absorber are open, i.e. set to the “Open”
position.
nflate the air chamber of the damper as de
-
scribed in the table. To deflate the air chamber,
first unscrew the al e cap. Now you can either
press the air valve down or press the air-release
lever on the air pump.
The air pressure in the rear suspension
element must not exceed the maximum
value stated in the associated operating
instructions.
