The Trance bike is capable of climbing and descent the most technical of trails. Trance 1 offer three ProPedal damping setting to reduces pedal induced suspension bob. You can find s setting that suits your riding style. Please follow the guidelines below in setting up and maintaining your Giant Trance bike. Shock spec: eye to eye : 165.1mm(6.5") shock travel: 38.1mm(1.5") hard ware: 22.2x6mm/40x6mm Setup for Trance 1 ( See Drawing #1 ) 1. Adjusting Air Pressure The air pressure needed is determined by the rider's weight and riding conditions. Increasing air pressure will make the shock stiffer. Decreasing the air pressure will make the shock softer. The shock should be set to sag 9mm or 1/4 of its stroke while the rider is seated on the bike in riding gear. See table 1 for recommend air pressure: TABLE 1AIR PRESSURE CHART Rider Weight lbs kg 90-100 41-45 100-110 45-50 110-120 50-54 120-130 54-60 130-140 60-64 140-150 64-68 150-160 68-73 160-170 73-77 170-180 77-82 180-190 82-86 190-200 86-91 200-210 91-95 210-220 95-100 220-230 100-104 230-240 104-109 240-250 109-113 250-265 113-120 265-280 120-127 280-295 127-134 Air pressure PSI 82-90 90-100 100-108 108-120 120-128 128-136 136-146 146-154 154-164 164-172 172-182 182-190 190-200 200-208 208-218 218-226 226-241 241-255 255-269 5 2. Rebound Adjustment Rebound damping controls the rate at which the shock returns after it has been com-pressed. The red adjuster dial can be turned clockwise for slower rebound and counter-clockwise for faster rebound. The proper rebound setting is a personal preference and varies depending on rider weight, riding style and riding conditions. 3. ProPedal RP3 Damping Adjustment ProPedal damping reduces pedal induced suspension bob. The three settings of the lever are full ProPedal, light ProPedal and Plush. Use the different settings to tune the shock to different riding conditions and situations. For example, use the full ProPedal position for riding to the top of the mountain and then switch to the Plush position for the descent. Switch between positions and select the one that reduces suspension movement most effectively while providing the desired amount of bump absorption.

Torque settings The bolts used to attach the rear suspension unit are very high grade products factory installed to specific torque specification. If it becomes necessary to remove or tighten the pivot bolts extreme care should be taken when re-tightening them. All bolts should be cleaned and re-set using LocTite Primer (243) All bolts location and tighten torque please refer to the illustration below. 2 3 4 6 1 5 Torque settings: 1. 2. 3. 4. 5. 6.
