2-4. Rear suspension tuning.
By adjusting the air pressure, the RockShox SID rear shocks can be tuned to your particular weight,
riding style and terrain. This shock has been designed to be tuned for soft, plush descent riding, for the
long climbs, or a combination of both.
Different riders require different performance characteristics from their suspension.
(A). Heavier or more aggressive rider needs a stiffer compression damping (spring), a higher air
pressure.
(B). Lighter rider needs softer compression damping (spring), a lower air pressure.
All Giant XtC dual suspension bicycles are equipped with front and rear shock absorbers that offer
some sort of adjustment and tuneability. Adjustment of suspension is subjective and cannot be 100%
prescribed by Giant. If help is needed, please contact your Giant dealer.
When experimenting with set up, remember that front suspension reacts differently to bump force input
than the rear shock.
When tuning suspension, always make one change at a time and write it down. This takes patience
and time, but allows you to understand how each change affects the ride. Use a familiar trail to make
small adjustments at a time. To understand the tuning range it may also help if the bike is ridden from
one extreme to the other (e.g. maximum vs. minimum rebound).
WARNING:
THE REAR SHOCK UNIT IS SERVICEABLE.
THIS SERVICE MUST BE PERFORMED WITH PROPER TOOLS BY AN
AUTHORISED ROCKSHOX DEALER OR BY ROCKSHOX. NOONE
ELSE SHOULD DISASSEMBLE OR OTHERWISE MODIFY THE
SHOCK UNIT OR ATTACHMENTS. DOING SO WILL NOT ONLY VOID
ALL WARRANTIES BUT CAN LEAD TO SERIOUS INJURY OR DEATH.
2-5. Rebound damping adjustment (only XtC Team, XtC Mt. Snow and XtC Big Bear).
The SID rear shock includes a red rebound damping adjustment knob (figure 2). Rebound is the
extension or return of the shock. Rebound damping adjustment allows you to control the rate at which
the shock extends after it is compressed. The shock's rebound is quickest when the adjustment knob is
in the full anti-clockwise position. Rebound is slowest when the adjustment knob is in the full clockwise
position.
Setting rebound:
When you are setting rebound, a good starting point is the “curb” test. Be sure this is done after you set
up your “Zero-Sag”.
1. Set your rebound adjuster fully anti-clockwise.
2. Ride the bike off the curb sitting in the saddle and count the number times the shock bounces. You
want to achieve one bounce.
3. Turn the rebound adjuster a quarter turn clockwise and ride off the curb again. Continue to do this
until one bounce is achieved.
4. Record the number of turns from the fully closed (full anti-clockwise) position.
