Operation
6.5.13.2 Adjusting the Suntour rear frame damper
Only applies to pedelecs with this equipment
Every rear frame damper has a specific delivery
air pressure ex works.
These levels are starting
points. These settings can be changed based
on riding skills, trail conditions, frame design
and personal preferences.
After setting up the rear wheel damper, check the
sag to ensure the recommended sag settings are
used.
The fork sag is adjusted.
When adjusting the sag, ensure that the
compression and rebound adjuster is in an open
position, i.e. the
lockout lever
is in the OPEN
position.
1
Remove the valve cap from the
air valve
.
2
Attach a fork/damper pump to the valve.
3
Pump the damper to the required pressure.
Never exceed the recommended maximum air
pressure.
4
Detach high-pressure damper pump.
5
Measure the distance between the air chamber
seal and the end of the rear frame damper.
This distance is the
total rear frame damper
deflection
.
6
Use the O-ring or a cable tie on the damper
body to gauge the sag correctly.
7
Put on your normal cycling clothing, including
baggage.
8
Sit on the pedelec in your usual riding position
and support yourself against an object, such as
a wall or tree.
9
Push the O-ring or cable tie downwards
against the air chamber seal.
10
Get off the pedelec without the suspension fork
deflecting.
11
Measure the distance between the air chamber
seal and the O-ring. This measurement is the
sag. The recommended value is between 25%
(hard) and 30% (soft) of the
total rear frame
damper deflection
.
12
Increase or reduce the air pressure until you
have reached the desired sag.
If the sag is correct, fasten the
valve cap
onto
the valve.

Notice
The damper can be permanently damaged if the

exceeded or not reached.
Do not exceed the maximum air pressure of
300 psi (20 bar).
