6.4.13.1 Adjusting the SR Suntour rear frame damper sag
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.

Adjusting the suspension fork sag (see
Section 6.4.12).
The compression lever is set to OPEN.
1 Remove air valve cap from the air valve (rear
frame damper).
2 Attach a high-pressure damper pump to the air
valve (rear frame damper).
3 Pump the rear frame damper to the required
pressure. Never exceed the recommended
maximum air pressure from the Suntour rear
frame damper filling pressure table (see
Table 31).
Notice
If the air pressure in the rear frame damper is
exceeded or undershot, the damper can be
permanently damaged.
4 Remove high-pressure damper pump from the
air valve (rear frame damper).

5 Apply force on the saddle to compress the rear
frame damper several times by at least 50% of
the full deflection.
This equalises the air pressure between
positive and negative air chambers.
6 Measure the gap between the air chamber seal
and the end of the rear frame damper. This gap
is the total deflection (rear frame damper).
