User manual GIANT BICYCLES SIERRA NEVADA BIKES-2001

[. . . ] EXPEDITION ­ SIERRA NEVADA Model Year 2001 Owners Manual December 2000. · · · · · · FULL SUSPENSION TRAVEL BIKES Full Suspension travel bikes with 26" wheels. TM NRS (No Resonance System) suspension with "no-SAG" set-up. Sealed bearings on main pivots: BB shell - chain stays Linkage plates - seat tube Seat stays - linkage plates. Sensitive rear shock works even on the smallest bumps. CONTENTS: 1. [. . . ] Push gently one of the pedals, like you would do during real riding (while keeping the front wheel locked with the front brake). Shift your body weight gently from the saddle to the front fork and try to dismount without causing too much movement in the bike. If yes, this means there is some "SAG". TM REMEMBER: FOR MAXIMUM EFFICIENCY THE NRS SYSTEM SHOULD ALWAYS BE SET UP WITH ZERO "SAG" !!!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. - Pag. It is essential to set up the NRS system with zero "SAG". Here's the final check: ride the bike with TM 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. Note: the air pump which is supplied free of charge with the bike is equipped with an escape valve (the black knob below the gauge) to de-pressurise the shock when the pressure is too high. 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. 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. 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. 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. [. . . ] 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. INDEX 2-5. To increase or control the air pressure of the shock, a special air pump is needed. TM A pump is supplied with each NRS bike. [. . . ]
