[. . . ] Please refer to the specific shock manufacturer's technical manuals for more information on how to adjust the shock equipped on the Giant dual suspension bicycle. rebound damping Rebound damping controls the rate of speed at which the shock returns to its original position after responding to a bump force. Rebound damping prevents the shock from springing back too quickly. This is desirable because it improves the rear suspension's sensitivity to small bumps and the tire's ability to stay in contact with the ground. [. . . ] Measure the eye-to-eye distance while they're seated on the bike (Figure 1). Subtract the weighted eye-to-eye distance from the un-weighted eye-to-eye distance to determine sag. See the Sag Recommendations Chart for sag distances. Spring Tension Collar Eye-to-Eye Fig. 1: (Model: Faith) 240 SETTING AND ADJUSTING SAG (Coil Shocks) cont'd 5. For general purpose riding, the shock should compress approximately one quarter of its travel (please refer to the Sag Recommendations charts for specific recommendations for the frame). Turn the shock's tension collar clockwise to increase spring tension/decrease shock sag. If the rider sits on the bike with minimal tension on the spring and there is less than one quarter of the shock travel, a lighter weight spring is needed. If you turn the shock tension collar three complete turns and the shock compresses more than a quarter of the shock's travel, a heavier spring is needed. Contact your Giant Canada Inside Sales Representative for replacement springs. WARNING Never tighten the spring tension collar past three turns from minimum tension as doing so will cause the spring to "coil bind " which can cause damage to the spring and internal workings of the shock. service | Maestro Suspension Manual Sag Recommendations chart (coil shock) AIR SHOCK SETUP* *Applicable to the following bikes/ framesets: 241 service | Maestro Suspension Manual Reign X (AIR) Reign Trance X Advanced SL Trance X Cypher Anthem X Advanced SL Anthem X Anthem X W Yukon FX (6. 75"rear wheel travel) (6. 0" rear wheel travel) (5. 0" rear wheel travel) (5. 0" rear wheel travel) (5. 0" rear wheel travel) (4. 0" rear wheel travel) (4. 0" rear wheel travel) (4. 0" rear wheel travel) (4. 0" rear wheel travel) Suspension Settings and Recommendations (air Shock-Equipped Bikes) Giant cross-country, trail and all mountain bikes feature an air shock equipped Maestro suspension design. Maestro-equipped mountain bikes rely on rear suspension "sag. " Sag (see Basic Terms & Shock Setup Overview) is a critical performance component and is relative to the individual rider's weight. USING A SHOCK PUMP These simple steps will help your consumer get the most accurate use and longevity of their shock pump. When screwing the pump onto the shock do not screw it on all the way until it stops. This will damage the seal on the pump and also allow too much air to escape when you remove the pump. Watch the pressure gauge on the pump when you screw the pump onto the shock. Screw the pump on until the gauge registers a pressure and then another 1/4 - 1/2 turn. At this point you now have a strong air seal. When you remove the pump a small amount of air will always be lost. If you follow our recommendation above the pressure loss will only be approximately 5% rather than up to 50% if the pump is screwed all the way onto the valve. Because of this pressure loss when you have found a pressure that gives you the best performance from your frame you will need to add 5% extra pressure according to the gauge to leave the required pressure in the shock once the pump is removed. EXAMPLE: if the required pressure is 160psi, 5% = 8psi. Pump the shock until the gauge reads 168psi, remove the pump; 160psi will be left in the shock. 242 SETTING AND ADJUSTING SAG (air Shocks) cont'd 1. Pump the main air chamber to a psi equal to 100% of rider weight in pounds (2. 2lb = 1kg). [. . . ] 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 clockwise until one bounce is achieved. 243 service | Maestro Suspension Manual FRONT SUSPENSION TRAVEL & SAG GUIDE A suspension fork is effective at both absorbing bump forces and helping the tire to track the ground for improved traction and braking control. When in active mode, a fork will rely on sag to keep the front tire in better contact with the ground during braking. [. . . ]
