BICYCLING IS A HAZARDOUS ACTIVITY THAT REQUIRES THAT THE

RIDER STAY IN CONTROL OF HIS OR HER BICYCLE AT ALL TIMES.

READING THIS MANUAL ENTIRELY AND PROPERLY MAINTAINING YOUR BICYCLE AND SUSPENSION SHOCK

WILL REDUCE THE POSSIBILITY OF INJURY OR POSSIBLE DEATH. PRIOR TO RIDING YOUR BICYCLE, YOU

SHOULD INSPECT YOUR SHOCK TO ENSURE THAT NO DAMAGE HAS OCCURRED DURING THE COURSE OF

RIDING. DO NOT RIDE YOUR BICYCLE IF THE SHOCK SHOWS ANY SIGNS OF BENDING, CRACKING, LEAKING,

OR IF IT IS MISSING ANY OF THE ORIGINALLY SUPPLIED COMPONENTS. ANY FALL FROM YOUR BICYCLE

CAN RESULT IN SERIOUS INJURY OR EVEN DEATH. FOLLOWING THESE INSTRUCTIONS CAN HELP YOU

REDUCE THE RISK OF BEING INJURED. IF YOU HAVE ANY PROBLEMS WITH THIS SHOCK, CONTACT A

MANITOU AUTHORIZED DEALER WHO CAN ARRANGE FOR SHIPMENT TO ANSWER PRODUCTS, OR YOU MAY

CALL ANSWER TO HAVE IT SHIPPED DIRECTLY AT 800-423-0273.

WARRANTY INFORMATION

Any Answer Products shock found by the factory to be defective in materials and/or workmanship within

one year from the date of purchase (or two years in EU countries) will be repaired or replaced at the option

of the manufacturer, free of charge, when received at the factory with proof of purchase, freight prepaid.

This warranty does not cover breakage, bending, or damage that may result from crashes or falls. This

warranty does not cover any shock that has been subject to misuse or whose serial number has been

altered, defaced or removed. This warranty does not cover paint or other cosmetic damage. Any

modifications made by the user will render the warranty null and void. This warranty is expressly in lieu of

all other warranties, and any implied are limited in duration to the same duration as the expressed warranty

herein. Answer Products shall not be liable for any incidental or consequential damages.

If for any reason warranty work is necessary, return the shock to the place of purchase. In the USA, dealers

should call Answer Products for a return authorization number (RA#) at 800-423-0273. At that time,

instructions for repair, return, or replacement shall be given. Customers in countries other than USA should

contact their dealer or local distributor. For a complete listing go to www.answerproducts.com .

OPENING YOUR REAR SHOCK WITHOUT RELEASING PRESSURE SHOULD NOT BE

DONE. DOING SO WILL RESULT IN SERIOUS INJURY.

If your shock ever loses oil, air pressure, or begins to make noise, stop riding the shock and have the shock

inspected by an authorized Manitou dealer or contact Answer at 800-423-0273.

RIDING YOUR BICYCLE WITH IMPROPER SHOCK PRESSURE CAN RESULT IN LOSS

OF CONTROL AND POSSIBLE SERIOUS INJURY OR DEATH.

Swinger SPV shocks depend on the reservoir air pressure to create damping and function properly. The

air pressure range is 50-175 psi. A pressure within this range must be checked and maintained before

each ride. Use of the shock with improper air pressure can cause a total loss of damping and malfunction

of the shock.

CHECK FRAME AND SEAT POST FOR SHOCK CLEARANCE.

When the shock compresses, its position within the frame will change. Always

check for adequate clearance between the shock and frame/seat post through the entire stroke/motion of

the shock. Be careful not to lower the seat post below the bottom of the seat tube. It is the responsibility

of the user to check for adequate clearance between the shock and frame/seat post for the entire stroke/

motion of the shock. If your bicycle offers multiple shock mounting options, it is the user’s responsibility

to make sure that any mounting options also offer adequate clearance between the shock and frame/

rocker/seat post.

SPV PERFORMANCE FEATURES

Stable Platform Valve technology creates an efficient, firm platform to eliminate excessive movement

(bobbing) from low resonance forces such as pedaling. Upon bump impact, however, the SPV valve opens

to allow for massive amounts of oil flow to eliminate spiking and to absorb impacts. Since our shock does

not over-travel to absorb impacts, attitude and cornering stability are greatly improved along with the overall

stability of the bike. The ability to create an adjustable platform without spiking or compromise in

suspension performance is something that we’ve found cannot be achieved with simpler damping systems.

An additional benefit to the SPV system is that it has externally adjustable rebound damping and platform

threshold on all shocks, adjustable spring curve (via a 16 mm socket) on 4-way shocks, and high and low

speed compression adjustments on 6-way shocks. Externally adjustable damping allows for any rider to

achieve the optimum set up for any bike, trail conditions, and rider weight in minutes with no disassembly.

Position-sensitive compression damping allows for light initial damping and much heavier damping at full

compression.

SPV SUSPENSION TERMINOLOGY EXPLAINED

• Bobbing: The up and down motion that robs pedaling power. This movement occurs due to the pedal

pulse inputs (low resonance) and from weight shift during pedaling.

• Attitude and Ride Stability: Created by the SPV controlled damping action that manages excessive dive,

squatting, bobbing, chassis motion and the springy ride of conventional shocks that can throw a rider off-

line during aggressive riding and/or terrain.

• Stable Platform Damping: The new damping characteristics of the SPV technology that improves pedaling

and attitude/ride stability.

• Spike: The harsh feeling that occurs when riding over high velocity compressions such as sharp, square-

edge bumps, rocks, roots and big hits.

• Bump Dump: The shock’s ability to absorb the spike of high velocity (high-speed shaft movement)

compressions due to the massive compression flow available through the SPV system.

• Position-Sensitive Compression Damping: Damping that increases automatically depending on the

shock’s location in its compression stroke. Position-sensitive damping allows for light initial damping that

progressively increases as the shock is compressed.

• Sag: The amount of shock compression caused by the rider’s weight while positioned on the bike in a

normal riding position. Sag creates negative travel for better traction and control through turns and rough

terrain. With SPV, even the most energy conscious riders can run proper and even ample sag without

compromising pedaling efficiency.

• Spring Rate: The amount of force required to compress the spring a given length. English Standards are

measured in pounds to compress one inch (i.e. 400#/in.).

• Spring Preload: The difference between the free length of a spring and the installed length of the spring

when in a shock. Preload changes the starting force required to compress a spring.

• Air Spring Pressure: The air pressure that acts as the spring on air shocks. More pressure equals a firmer

and more progressive spring.

• SPV Air Pressure: The air pressure that controls the SPV compression damping qualities and

characteristics. More air pressure creates a firmer platform and increased compression damping. Less

pressure creates a lighter platform and more supple response.

• SPV Volume Adjustment: The volume adjuster located on the SPV shock reservoirs. This adjuster controls

how firm and progressive the position-sensitive compression damping feature acts. The smaller the volume

in the SPV chamber, the more progressive and position sensitive the compression damping becomes.

• Compression Damping: The amount of resistance created by the shock during the bump induced

movement of the shock. Compression damping controls how fast the shock is compressed by turning the

energy created during the bump force into heat and dissipating it.

• Rebound Damping: The amount of resistance created by the shock during the return movement of the

wheel. Rebound damping controls the speed at which the shock returns after being compressed, by turning

the energy created by the spring into heat and dissipating it.

SETTING UP YOUR SWINGER SPV SHOCK

The following information will guide you through the set-up and tuning of your Swinger SPV shock. SPV

technology offers the ability to quickly and easily tune the performance of your Swinger shock to your riding

preference, bike or terrain conditions and offers the highest performing shock technology available. When

setting up your Swinger shock USE THE FOLLOWING ORDER . First, make sure that pressure in the SPV

damper is between 50% and 70% of your body weight BEFORE MAKING ANY SAG ADJUSTMENTS . Only

after proper sag has been set should you then fine-tune your SPV pressure adjustment. 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 instructions below will walk you through the recommended

sequence for setting up your Swinger SPV shock.

1 SPV AIR PRESSURE – SPV technology depends on air pressure to function properly. Use of the

shock with improper air pressure will cause damage and failure of the shock and will void the warranty.

Note that this is not spring pressure, but is the valve located on the reservoir of the shock (for

“piggyback” models) or on the narrow damper end of inline shocks. 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. 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 shock pump and a 16 mm socket.

NOTE: NEVER open the shock in the locations shown in Photos 1 and 2.
