Giant Gtm-7 Coil Spring Shock; Setting Pre-Load And "Sag" Adjustment - Giant WARP 2004 Owner's Manual

4-2 Giant HV coil spring shock.
Giant Warp bikes are equipped with Giant HV coil spring type rear shocks. The drawing below shows such a
rear shock.
Figure 4.
A = Rebound damping adjust knob
B = Pre-load spring washer
C = Bumper
D = Pre-load spring (coil spring)
E = Knurled compression ring
The shock has a compression adjustment ring (knurled compression ring E) to set "SAG" and to pre-load the
spring (D). It has an external knob (A) to control an internal oil piston that regulates the rebound damping.
Softer and stiffer spring rates are available for these rear suspension shocks through your local authorised
Giant dealer.
For service in your country please also contact your dealer or the Giant importer in your country.

4-3 Setting pre-load and "SAG" adjustment.

Adjustment of the pre-load on the coil spring rear shock is simple. Looking at the front of the bike and the front
of the shock, facing the rear of the bicycle, follow these procedures:
For a stiffer spring, turn the knurled compression ring (E) clockwise to compress or load the spring.
For a softer spring, turn the knurled compression ring (E) anti-clockwise to relax or unload the spring.
"SAG" is the amount of shock travel that is used as the rider sits stationary on the bike and allows the bicycle
to perform as it was designed to. Typically, SAG is 25 - 30 % of all available travel.
To properly set the SAG, you will need a flat screw driver, measuring tape and/or calliper.
Step 1. Prepare the bicycle. Set the saddle to the correct height for your riding style.
Attach all accessories, bags, water bottles, etc. that you would normally ride with.
Step 2. Prepare yourself. Dress as you would for a normal ride, including helmet, cycling bag, etc.
Step 3. Use a flat screw driver or the like to slide bumper (C) of the shock piston against the main body of the
rear shock unit.
