9. Check the or O-ring. Did it slide down on the piston? If yes, this means there is still some "SAG".
REMEMBER: FOR MAXIMUM EFFICIENCY THE NRS™ SYSTEM SHOULD ALWAYS BE SET
UP WITH "ZERO-SAG" !!!
10. Increase the pressure of the positive spring in repetitive steps of 5 or 10 psi. following the points 7, 8
and 9 until "zero-SAG" is reached.
11. It is essential to set up the NRS
NRS™ system with a relatively high RPM on a nicely paved road. In case the bike tends to "bob" with
small motions, then increase the positive spring by another 10 psi. Now try again and the result
should be, that the bike does not "bob" anymore, whether sitting on the saddle or climbing or
sprinting out of the saddle.
12. Note: the air pump which is supplied free of charge with the NRS™ bike is equipped with an escape
valve (the black knob below the gauge) to de-pressurise the shock when the pressure is too high.
13. Note: the shock setting should be checked regularly (at least every 2 weeks). Of course the simplest
way to check is the asphalt paved road test with high RPM (see point no. 11).
14. Note: by putting the pump on the shock, the valve is opened and always some air pressure will be
lost (between 10 and 15 psi.). By taking the air pump from the valve no air pressure will be lost.
A small amount of air can be heard escaping, this is between the valve and the gauge.
15. Note: when the shock is set up for the first time and has to be inflated from 0 psi., the temperature in
the air chamber will rapidly rise. Afterwards the temperature inside will drop slowly. Together with the
drop in temperature some air pressure will be lost. Therefore the pressure has to be checked again
after approx. 15 minutes.
16. Note: air shocks are sensitive to big temperature changes. Especially in winter when the bike is
taken outside, the air pressure setting has to be checked again outside.
17. Once you understand the routine of correctly setting up the NRS
experienced what the bike can do for you (MORE POWER), you can then try to slightly modify the air
shock setting to your own personal needs.
Always maintain the "ZERO-SAG" principle.
Have fun!
