4. Rear suspension.

The rear suspension for your Giant VT bicycle / frame kit is provided by a Manitou Swinger SPV

3-way adjustable air shock.

For a description of the coil spring shock, see http://www.answerproducts.com or the Manitou

owner’s manual that comes with your bike or frame kit.

WARNING:

Improper adjustment of rear suspension shock can result in unstable conditions or loss of

control.

4-1 Adjusting travel.

Your Giant VT bicycle gives you the ability to change the rear wheel travel with minimal effort. This

is accomplished by multiple positions for the lower shock pivot bolt (see figure 3 below).

To change the travel:

1. Using a 6 mm. Allen-key, remove the lower shock mounting bolt.

2. Pivot the shock backward or forward to align the eyelet with one of the holes.

- The most forward position is for 5.6” travel.

- The most backward position is for 5.0” travel.

3. The threads of fixing bolt should be cleaned and re-set using LoctiteTM Primer (#7649) and

LoctiteTM blue Removable Threadlock (#242) or similar material.

Install the bolt and tighten to the proper torque of 10-12 Nm.

4. After any adjustment is made to travel, you will need to readjust all pre-load settings.

WARNING:

Improper (dis-)assembly may result in damage to the bicycle or in an accident which can

cause serious injury or death.

SPV SET-UP QUICK REFERENCE GUIDE.

This quick reference guide is to be used for setting up the Swinger air shock. Follow this order to

ensure the best possible tuning.

Air Shock Initial Set Up:

1. Adjust Sag: Sag is the amount the shock compresses under normal body weight.

Cross country: 25-30% Sag

Freeriding: 30-40% Sag.

2. Set SPV Pressure: range should be between 50 and 175 psi. Pressure should be between

50-70% of body weight. More pressure will create more compression damping, hold the bike

up more and pedal better. Less pressure will create less compression damping, allow more

sag, and be more responsive and supple.

3. Rebound Damping: Turn the blue knob located on the eyelet mount clockwise to increase

rebound damping.

The rear shocks are serviceable and must be returned for maintenance, repair or service, only to an

authorised Manitou dealer (or the Manitou 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 Manitou dealer or by the Manitou distributor in your country.

4-3 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 Manitou dealer or to the

Manitou distributor in your country to inspect and repair.

(Note: this is not covered under the terms of the warranty).

WARNING:

Do not try to disassemble or to replace the rear shock or a pivot by yourself !

Improper (dis-)assembly may result in damage to the bicycle or in an accident which can

cause serious injury or death. Only an authorised Giant dealer should disassemble the rear

shock or pivots.
