[. . . ] These are especially recommendable if you have a single link rear suspension system, because they compensate the movements coming from the bearing play of the rear suspension what significantly prolongs the life of the shock absorber. When using radial joints the usage of rubber joint rings is obligatory. When using standard bushings these are optional.

Variation of the valve of the negative chamber If the shock absorber does not have enough room to work because of the valve position or when this valve position makes the filling of the air chamber impossible, you will have to change this. The change of the valve position is only possible when the shock absorber is not under any air pressure. (Read chapter 3. 1 to learn how to reduce the air chamber pressure. ) When the AiR-force SLR is absolutely pressure free, you can unscrew the mounting ring of the air chamber (one rotation is enough ­ clockwise thread). Now you can rotate the valve clockwise and define its position relatively to the shock absorber fixing eyelets. When you have achieved a satisfying position of the valve you can screw the mounting ring on again by hand. If the position of the shock absorbers eyelets is not aligned, change their position through turning clockwise. Do not turn parts of the shock absorber counter clockwise to each other because you might unscrew parts of the shock absorber (threaded connections).

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) Pressure main chamber in bar Pressure negative chamber in bar 5 8, 5 6 10, 2 7 11, 9 8 13, 6 9 15, 3 10 17 11 18, 7 12 20, 4 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.

Inspection The rear shock absorber is object to general wear and tear, so that a servicing every year or earlier depending on ride conditions is obligatory. Even storage of the shock absorber leads to the aging of the seals (oil loss, smacking and slurping sounds, shock absorber failure) and makes a servicing necessary!An inspection consists of an oil change (silicon oil) as well as a change of all seals and small function parts.
