AIR SHOCK SET-UP 
Giant cross-country and trail bikes feature an air shock equipped Maestro 
suspension design. All rely on sag for proper riding performance.  
 
SETTING AND ADJUSTING MAESTRO (ANTHEM) SAG (air shock) 
1.  Pump the main air chamber to a psi (pounds per square inch) equivalent 
to rider’s body weight .  
2.  Push the rubber O-ring that is around the shock’s shaft all the way 
against the base of shaft (closest to shock body).  
3.  Position your bicycle next to a wall so that you can sit on the bike with 
both feet on the pedals while steadying yourself with one arm. Gently sit 
on the saddle without bouncing. Dismount gently and look at how far the 
O-ring has moved down the shaft. Measure distance O-ring has moved.  
 
 
 
4.  Add or remove air until desired shock movement is obtained. Refer to the 
Sag Recommenda-tion Guide below for proper sag measurements. 
 
Maestro Sag Recommendations: Anthem: 1/4” (6mm) O-ring movement  
 
 
SETTING AND ADJUSTING REBOUND DAMPING 
1. If you are unfamiliar with rebound damping, perform this procedure: With full 
body weight, push down on the saddle forcefully to compress the shock. Watch 
(and feel) how the shock rebounds from compression.  
 
2. Next, turn the rebound damping knob clockwise until it stops and compress the 
shock under full body weight. Note that the shock rebounds very slowly. Next, turn 
the damping knob counterclockwise a few turns and re-perform your compression 
testing until the shock rebounds just slightly more slowly than with no damping.  
 
3. To check the rebound damping rate while riding, ride off a curb while seated.  
The rear suspension should bounce only once upon rebound (the heavier the rider, 
the more damping will be required). Adjust accordingly to accomplish this motion. If 
the suspension bounces more than once, turn the damping knob in the appropriate 
direction until one bounce is achieved.
