Selecting Air Pressure, "Zero-Sag" Adjustment - Giant XTC BIKES-2001 Owner's Manual

How to change the position of the rear shock:
1. Use a 5 mm. Allen-key to remove the bolt that holds the upper end of the shock to the linkage
plates. Take note of the position of each part when removing, to insure proper re-assembly.
2. Pivot the top of the shock towards the desired shock mounting holes in the linkage plates.
See figure 3 which holes to use for position "1" or position "2".
3. Re-install all parts in reversed order.
The threads of fixing bolt should be cleaned and re-set using Loctite
TM
Loctite blue Removable Threadlock (#242) or similar material.
Recommended tightening torque of the fixing bolt: 12~15 Nm.

control of an NRS bike.
Do as follows:
1. Try the air pump on the valves and make sure the air pressure opens the valves, air goes into the
air chamber and does not stay in the pump hose.
2. Try to find out your exact body weight including cycling gear (clothing, helmet, shoes, cycling
bag.......).
3. Check the following table to find the correct "positive" and "negative" air pressures, depending on
your weight:
