3. Adjustment
3.1.
Primary filling
The AiR-force SLR is already filled with air when you receive it from your dealer. To adjust the
pressure or 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.
When removing air from the shock absorber: First remove air from the negative chamber!
When filling: First fill the main air chamber, then the negative chamber.
NOTE! 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!

Air pressure Air-force SLR (only recommended values)
The minimum air pressure in the main chamber is 5 bar, the maximum pressure is 20 bar. The
negative air chamber should have a minimum pressure equal to the pressure of the main
chamber and a maximum pressure of 1,7-fold main chamber pressure (up to 4 bar more than
the positive chamber).
3.2. Spring
rate
The spring rate defines the firmness of the ride and is varied by changing the air pressure. If
you are a marathon or cross-country rider you will probably prefer a firmer ride, while comfort or
free rider would prefer a rather soft ride. The best spring rate cannot be precisely defined by the
manufacturer because of these different riding styles. If you want to make the shock absorber
firmer, you have to increase the air pressure in both chambers. If you want to soften the shock
absorber, do vice verse.
Large amount of negative travel = Soft spring rate (for free ride, downhill and comfort)
Small amount of negative travel = Hard spring rate (cross country and marathon)
