Sag" Adjustment - Giant AC BIKES-2001 Owner's Manual

The rear shocks are serviceable and must be returned for maintenance, repair or service, only to an
authorised RockShox dealer (or call the RockShox distributor in your country) once a year or more
often if the bike is used in extreme conditions.
This service is not necessarily free of charge!
WARNING: All service and maintenance of the rear shocks should only be performed
with proper tools by an authorised RockShox dealer or by the RockShox distributor in
your country.
3-3. Rear suspension tuning.
To adjust the pre-load on the coil-spring shock is simple.
For a firmer ride while descending or hill climbing on smooth surfaces, turn the spring pre-load collar
against to compress or load the spring.
For a softer ride while riding cross country, turn the spring pre-load collar away from the spring to relax
or unload the spring.
WARNING: Turn the spring pre-load collar away from the spring and stop turning just as
the spring feels loose on the shock. This is zero pre-load. Do not exceed 2.5 full turns
of the threaded spring collar from zero pre-load. Too much spring tension will cause
the spring to fail.
If the pre-load required exceeds 2.5 full turns of the spring pre-load collar from zero pre-
load, you may require a higher rated spring. Contact your authorised Giant dealer or the
manufacturer of the shock for an optional replacement spring.
WARNING: Never set the spring pre-load collar so there is no pre-load on the spring. If
the required pre-load adjustment ring setting results in no pre-load on the spring or proper
adjustment can not be achieved, you may require a lower rated spring. Contact your
authorised Giant dealer or the manufacturer of the shock for an optional replacement
spring.

3-4. "SAG" adjustment.

SAG is the amount of coil spring pre-compression that is required to compensate for the riders weight
and allow the bicycle to perform as it was designed to.
To properly set the SAG, you will need a 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, 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. Push the bumper against the pre-load spring washer with a flat screw driver.
Measure the distance (L) between the main cylinder and the bumper of the rear shock.
Turn the spring pre-load collar away from the spring and stop turning just as the spring feels
loose on the shock. This is zero pre-load.
