3.1 Primary
filling
The AiR-force SLR is already filled with pressure from 6-8 bar by delivery. To adjust the
pressure, for testing the clearance of the shock absorber or for the adjustment of the valve
position it might be necessary to remove the air from the shock absorber.
Please check, if your air pump has an adapter for filling shock absorbers, which makes the
removal of the pump possible without loosing air pressure. It’s available in every specialist shop.
1. Release air: Put off the valve cap, hitting the valve (golden nib) and the air pressure will
remove.
2. Before you start filling: The damper has to be in maximum travel position.
NOTE!
Check at
first that the damper is totally stretched.
3. Filling:
The necessary pressure depends on your weight, the ratio of the bike and the
application area. Fit your suspension pump and fill the damper by pumping
according to table
(picture 1.3).
NOTE!
Sometimes the damper is pushed together by filling in the pressure, than you have to
release the air, pull it until the damper is totally stretched and refill again
!
In our opinion the standard sag (negative travel) amounts 15-20% (4.5 – 6mm, 100% travel =
30mm). You will have the best performance in this area of sag. Below you’ll find a small table
with points of reference.
You can choose your pressure like you want but keep the two following points in mind:
- Lower pressure means: More sag, more comfort, less breakdown rating safety
- Higher pressure means: Less sag, less comfort, high breakdown rating safety
You can use a binder or rubber ring on the oil chamber to measure the negative travel.
