SETTING UP YOUR SWINGER SPV REAR SHOCK
The following information will guide you through the set-up and tuning of your
SWINGER SPV rear shock. SPV technology offers the ability to quickly and easily
tune the performance of your SWINGER rear shock to your riding preference, bike
or terrain conditions and offers the highest performing rear shock technology
available. When setting up your SWINGER rear shock USE THE FOLLOWING
ORDER. First, set the pressure in the SPV chamber to roughly 75 psi (5 bar)
BEFORE MAKING ANY SAG ADJUSTMENTS. Only after proper sag has been set
should you then fine-tune your SPV pressure adjustment (see page 4 for sag
adjustments). SPV volume adjustments should follow as necessary. You should
allow for a minimum of one-hour break-in period prior to determining your
preferred settings. The sequence of the adjustment instructions below will walk
you through the recommended order of adjustments.
SPV Air Pressure –
SPV technology depends on air pressure to function
properly. Use of the rear shock with improper air pressure will cause damage
and failure of the rear shock and will void the warranty. Note that this is not
spring pressure, but rather is controlled by the RED SCHRADER valve. The air
pressure settings control the starting compression force that affects the pedaling
platform and bump-dump blow-off, as well as the overall compression damping
characteristics. This is the primary adjustment of SPV technology. The SPV air
pressure range is 50-175 psi (3.5-12 bar).
NEVER USE A PRESSURE BELOW OR ABOVE
THIS RECOMMENDED PRESSURE RANGE.
SEE WARNING ABOVE.
To quickly get "in the ballpark" for your weight, set the starting SPV pressure at
50-70% of your weight. The air pressure also affects the sag, so you should set
the air pressure before setting the spring (main spring air pressure or coil preload)
and sag. The air pressure setting will vary according to the following: 1) rider
weight, 2) spring rate, 3) bike leverage ratio, and 4) personal preference. Lower
pressures will create a lighter platform for a softer ride and lower blow-off
threshold to the bump-dump feature. Higher pressures will provide a firmer
platform for firmer pedaling, firmer ride control and a higher blow-off threshold to
the bump-dump feature.
Once you find an acceptable setting, note that this may not be the optimal setting
for all riding. Some courses or trails may have more pedaling sections (requiring
higher SPV pressure), some may have more small "chatter bumps" (requiring
lower SPV pressure) and some may have more big hits, drops and jump landings
(higher SPV pressure and volume ramp). With SPV, this can all be done in a matter
of minutes with an air rear shock pump and a 16 mm socket.
Adding SPV Air Pressure –
valve (located on either the "piggyback" reservoir or on the narrow damper end of
inline rear shocks). Attach the Manitou SPV pump (Part #85-4163) or a similar
pump to the red Schrader valve. You can damage the pump by screwing it on too
far, so as soon as the gauge registers pressure, screw 1/2 turn more and pump to
the desired level. You can use the micro-adjust feature on the SPV pump to fine
tune your air pressure. The slight hiss you hear when unscrewing the pump is
primarily the air left in the pump and may affect your pressure setting in the rear
shock very little. [NOTE: larger hisses (leaking air) may be the result of a loose
Schrader valve core.] Likewise, when you install the pump, the rear shock will fill
the pump and reduces the registered pressure previously installed in the rear
shock. This usually is a 10-15 psi difference between what was in the rear shock
and what the pump is reading. This is all normal procedure when adjusting the
SPV rear shock pressure. After removing the pump, be sure to reinstall the
Schrader valve cap. If the rear shock does not dampen properly after pressurizing,
the air pressure was lost during pump removal as a result of a worn or malfunc-
tioning pump fitting o-ring OR the Schrader valve core may need to be tightened.

AIR VOLUME ADJUSTER SETTINGS
The SPV air volume settings control the position sensitivity compression damping
feature of the rear shock. The SPV air chamber volume adjuster is either the red 16
mm nut or the red knurled, no-tools volume adjuster that is located on the end of
the reservoir, depending on which rear shock model you own. The volume adjuster
controls the rear shock's bottoming resistance by varying the rise in compression
force during the last 50% of the rear shock stroke. We recommend using the SPV
Volume Tuning Socket shown below (part #85-3007) to tune this adjustment. This
tool has markings that easily show where the volume adjustment is in its range.
The SWINGER rear shock's volume adjuster nut has just over 5 turns of
adjustment range, while the no-tools volume adjuster has 4 settings. Turning the
adjuster out (counterclockwise) makes the volume larger and decreases the
compression damping and bottoming resistance during the last 50% of the rear
shock stroke, leading to a more linear spring rate. Turning the adjuster in
(clockwise) makes the volume smaller and increases the compression damping
and bottoming resistance during the last 50% of the rear shock stroke, leading to
a more progressive spring rate. As a general rule, you will use a smaller air volume
with lower pressures and a larger air volume with higher pressures. The air
pressure will change when adjusting the volume. Changing from full out to full in
corresponds to a 15 psi increase in SPV air pressure, so always readjust your air
pressure to your preferred settings after adjusting the air volume.
The no-tools volume adjuster has four numbered chambers with different volumes.
The #1 position has the largest volume, so this is the least progressive of all of the
settings. The #4 position corresponds to the most progressive feel.
When the volume adjuster assembly has reached its
clockwise or counterclockwise stop limit, continued
force on the adjuster may cause damage to the adjuster mechanism that is not
covered under warranty. Do not try to continue to rotate the adjuster once you
feel resistance.
ADDITIONAL ADJUSTMENTS FOR REVOX AND SWINGER 6-WAY
COIL REAR SHOCKS
REVOX and SWINGER 6-way coil rear shocks offers two additional compression
damping adjustment features. These two adjustment knobs are located on the
reservoir base and allow for extreme fine-tuning of the rear shock's velocity/speed
sensitive compression damping characteristics. The red knob controls low-speed
com pression and the black knob controls high - s peed com pression. You can choose
to leave these two adjustments at their mi ni mum se tti ng (all the way out cou nter-
clockwise) and just use the SPV air pressure and volume adjustments to control
the compression damping. If you choose to fine tune the rear shock with these
adjusters, the following information will help you make the most of the features.
Over turning the high and low speed pressure
adjustment screws IN EITHER DIRECTION will damage
the adjusters and valves. ONLY turn these adjuster screws until you feel
resistance and then STOP .
Low Speed Compression Damping Adjustment –
controls low-velocity rear shock compressions and general ride firmness, and adds
additional chassis-stability platform to the bike. Lighter (counterclockwise)
adjustment provides a more supple/active ride but less chassis stability. Firmer
(clockwise) adjustments provide a less supple/active ride but greater chassis
stability platform. Starting at the minimum, turn the adjuster in until you achieve
the stability platform desired without any "spiking". As a general rule, a firmer
setting of the low speed compression will allow for lower pressures in the SPV
reservoir and larger volume settings. Optimal performance will be achieved by
balancing the low speed compression with the SPV pressure settings.
