This bike falls between XC race-inspired NRS and XC super long travel VT . the category name is
Trail /Enduro .
The rear suspension system is a new design which is called maestro , this maestro feature is vpp
design and to get the overall suspension behavior to the best not only one point is the best .
1. Minimal power loss
2. Low kickback
3. Minimal brake lockout
4. Linear rising rate suspension design
5. Best traction

2.Rear shock
The Trance series is all purpose dual suspension cross country bike. 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:

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.

3. 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.
