- Pag. 6. - 

There are no serviceable parts inside these Giant shock units. For maintenance, repair or service, return 

only to an authorised Giant dealer (or call the Giant 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! 

 

WARNINGS: 

 

All service and maintenance of the rear shocks should only be performed with proper tools by 

an authorised Giant dealer or by the Giant distributor in your country. 

 

Do not 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. 

There’s high pressurised gas inside the shock. 

Also, don’t place it into the fire. 

 

Don’t turn the rebound damping adjust knob with pliers or another tool.  

Only use your fingers to turn the knob to adjust the rebound damping.

 

 

 

4-3  Selecting rear travel. 

    

NRS™ bikes have 2 possibilities to mount the rear shock unit. 

These settings offer the rider the choice of 2 different rear suspension characteristics, depending on 

personal preference, how fast or slow the course is and how high or low the shock impacts are.  

 

Position “1” results in a 3” maximum rear wheel travel, with a high rebound speed. 

Position “2” results in a 3¾” maximum rear wheel travel and a lower  rebound speed.  

The ideal setting cannot be prescribed by Giant, but here are some tips: 

Position “1” with 3” travel may be an option for fast races or courses with relatively low shock impact 

(smooth terrain). Because in this setting the rear shock unit doesn’t need such a high “positive” air 

pressure, it’s also recommended for heavier riders, say 80 kg. or more. 

Position “2” with 3¾” travel may be more suitable for slower and very technical races or courses with 

relatively high shock impact (rough terrain). In this position the rear shock unit needs a higher “positive” 

air pressure, so it’s less suitable for heavier riders. 

 

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.  Pivot the top of the shock towards the desired shock mounting holes in the linkage plates. 

See figure 4 which holes to use for position “1” or position “2”.
