SHOCK PUMP
Specialized offers a rear shock pump. To add or release air pressure from your
Specialized rear shock. Follow the steps below:
Remove the valve cap from the shock. „
Thread the pump’s valve chuck onto the shock’s Schrader valve, until pressure „
registers on the pump gauge. Do not over tighten the valve chuck. If there’s no
pressure in the shock, no pressure will register on the pump gauge.
Stroke the pump until you’ve reached the desired pressure (see specific model „
air charts for pressure ranges). Pressure can be decreased by pressing the
pressure release button on the pump body.
When the valve chuck is removed, air pressure will be released. This air is NOT from
the shock. It’s leftover air from the pump hose. When the pump is reattached to the
valve, pressure in the shock will decrease to fill the pump hose. This will lower pressure
approximately 10 PSI (i.e., a shock set at 150 PSI will show approximately 140 PSI when
the pump’s hose is re-installed on the shock, as the hose is refilled by pressure in the
shock).
WARNING! Shock pressure range is 50 to 300 PSI. Do not exceed 300 PSI.
SETTING SAG
Setting the sag is necessary to get the best performance from your rear shock.
Proper sag is based on a percentage of shock stroke. To determine proper sag, please
follow the steps below.
Sag is determined by lightly sitting on the saddle without bouncing (applying rider
weight only to the shock) to compress the rear shock and displace the o-ring (see
fig.1). The distance between the o-ring and the shock seal is the sag.
The rider should be fully dressed in ride gear and sitting in a normal riding position
when setting sag.
OPTION 1: 2007 and newer Specialized models come with a small sag meter, designed
to help you find the correct starting point for sag, by measuring a preset distance from
the shock seal to the o-ring. Follow the instructions to displace the o-ring in order to
measure sag. Place the sag meter against the shock seal, if the o-ring falls inside the
sag meter notch, your shock is in the proper starting range for sag.
OPTION 2: Determine the sag measurement in millimeters. See specific bike model
setup page for sag %, shock stroke and displacement amount. Follow the instructions
to displace the o-ring in order to measure sag. Measure the distance from the shock
seal to the o-ring (B in fig. 1).
