2. Rear suspension. 2-1. NRS rear suspension system. (No Resonance System) bikes are equipped with dedicated RockShox SID rear shocks. These SID shocks have separated “positive” air chambers (spring) and “negative” air chambers (spring). The positive springs’ main function is to absorb the shock impact. The negative spring (which is much smaller) makes the positive spring function smoothly and prevents a harsh top out feeling when the shock returns to its original position.
2-2. Selecting rear travel (only XtC Team, XtC Mt. Snow and XtC Big Bear). XtC Mammoth and XtC Napa have just one possibility to assemble the rear shock unit: the so called “Marathon” setting. This setting has been developed to insure maximum control: fixed maximum rear wheel travel of 3¾”, with relatively low shock rebound speed.
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.

4. Inflate the air chambers until the correct pressures have been reached. Start with the negative spring (LOWER VALVE, on the small diameter of the shock) and next the positive spring (TOP VALVE on the large diameter of the shock). 5.
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.
2-6. Removing the rear shock assembly or pivots. It is necessary to periodically check the rear shock unit and the suspensions’ pivot points for damage or wear. The rear shock unit should be returned to an authorised RockShox dealer or to the RockShox distributor in your country to inspect and repair.
3. Cleaning and maintenance. Proper maintenance of a Giant XtC dual suspension bicycle is important to insure years of trouble free safe riding and enjoyment. We recommend taking this bike to your authorised Giant dealer for periodic service and inspection of suspension systems.
