Operation
7 Attach cable tie if there is no O-ring on the
damper body.
8 Put on your normal cycling clothing, including
baggage.
9 Ask someone to hold the pedelec. Sit on the
pedelec in your usual riding position and
support yourself against an object, such as a
wall or tree.
10 Apply force on the saddle to fully deflect the
rear frame damper gently two or three times.
11 The helper pushes the O-ring or cable tie
downwards against the air chamber seal.
12 Get off the pedelec carefully, ensuring that the
rear frame damper does not deflect.
13 Measure the distance between the air chamber
seal and the O-ring.
This measurement is the sag. The
recommended value is between hard (lowest
value) and soft (highest value).
14 The air pressure must be adjusted if the
required sag level is not reached.
Increase the air pressure to reduce the sag.
Decrease the air pressure to increase the sag.
15 If the sag is correct, replace the valve cap on
the air valve (rear frame damper).
16 If you are unable to achieve the required sag,
the fork will need to be adjusted internally.
Contact specialist dealer.

Adjusting preload internally
1 Release all the air from the main reservoir.
2 Remove the O-ring from beneath the air
chamber.
3 Rotate the high-pressure cuff (high volume)
and press downwards.
4 Add or remove the required quantity of volume
spacers.
Adding air volume spacers creates a more
progressive sensation when riding. A more
progressive sensation prevents rough
bottoming-out and stops the damper from
remaining low in the deflection range.
Removing air volume spacers creates a
stronger, linear sensation when riding. It helps
to remove the air volume spacers if the full
deflection cannot be achieved or the rear frame
damper becomes very hard at the end of the
travel. Push high-pressure cuff upwards and
tighten.
The air reservoir is air-tight.
5 Attach O-ring.
