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 3 which holes to use for position “1” or position “2”.

3.  Re-install all parts in reversed order.

The threads of fixing bolt should be cleaned and re-set using  Loctite

TM

 Primer (#7649) and

Loctite

TM

 blue Removable  Threadlock (#242) or similar material.

Recommended tightening torque of the fixing bolt: 12~15 Nm.

WARNING: 

IMPROPER (DIS)ASSEMBLY MAY RESULT IN DAMAGE TO THE
BICYCLE OR IN AN ACCIDENT WHICH CAN CAUSE SERIOUS
INJURY OR DEATH.

2-3.   Selecting air pressure, “zero-SAG” adjustment.

WARNING: 

IMPROPER ADJUSTMENT OF REAR SUSPENSION SHOCKS CAN RESULT IN
UNSTABLE CONDITIONS OR LOSS OF CONTROL.

How to set up the rear shock correctly with “zero-SAG”, in order to maximise the efficiency, comfort &
control of an NRS

TM

 bike.

Do as follows:

1.  Try the air pump on the valves and make sure the air pressure opens the valves, air goes into the

air chamber and does not stay in the pump hose.

2.  Try to find out your exact body weight including cycling gear (clothing, helmet, shoes, cycling

bag…….).

3.  Check the following table to find the correct “positive” and “negative” air pressures, depending on

your weight:

“PRO RACING” setting

“MARATHON” setting
