INTRODUCTION
Congratulations on your purchase and welcome to the finest line of suspension
bikes available!
Your bike is equipped with a Specialized AFR suspension unit. Please read the
following information for proper setup and service before riding. Please contact
Specialized at (877) 808-8154 for any questions.
Please read the following warnings. Because failure to follow any warnings may
result in a catastrophic failure, resulting in serious personal injury or death, this
phrase may not be repeated in connection with each Warning.
WARNING! Make sure you have, review, and understand the warnings,
instructions, and content of the manuals for your bicycle.
SERVICE AND MODIFICATIONS
As a first point of contact for all warranty or service issues, please refer to
your local authorized Specialized dealer. Any service must be performed by an
authorized Specialized Service Center.
Technological advances have made frames and shocks more complex, and the pace
of innovation is increasing. It is impossible for this manual or the accompanying
manuals to provide all of the information required to properly repair and/or
maintain your shock. In order to help minimize the chances of an injury, it is critical
to have work performed by an authorized Specialized Service Center.
Do not modify your shock or bicycle. Any modifications, non-authorized
replacement parts or improper service will void the warranty and can cause
damage to the shock unit and/or frame and can cause injury to the rider.
Proper maintenance is critical to the optimal performance and lifespan of the
shock. Please follow the service schedule recommended in this manual. If your
shock ever makes any unusual noises or loses air/oil, stop riding immediately and
have the shock inspected by your local authorized Specialized dealer or by an
authorized Specialized Service Center.
NOTE: Specialized shocks are pressurized with Nitrogen (Brain tanks on Epic and
Stumpjumper models, internal shock body on Enduro SL models). The charged
section does not need to be opened to perform any cleaning or lubricating of the
main air chamber. The charged section of the shock should not be opened except
by an authorized service center. Attempting to open the charged section of the
shock is dangerous, can result in serious injury and will void the warranty.
If the shock is compressed or will not return with no load on the bicycle, do
not attempt to service. Have the shock inspected by an authorized Specialized
service center.
WARNING! Service on Specialized shocks requires special knowledge
and tools. Specialized recommends that all service and repairs be
performed by an authorized Specialized Service Center.
WARNING! Never modify your shock or frame in any way. Do
not sand, drill, fill, or remove parts. Do not install incompatible
after-market suspension parts. Riding with a damaged, broken,
malfunctioning or improperly modified frame or shock, can cause you
to lose control and fall.
Caution: Any modification of your frame or shock means that your
bike no longer meets our specifications and therefore voids your
warranty.
Caution: Specialized shocks are only for use on designated
Specialized bikes. Use of these shocks on any non-recommended
bikes can result in poor performance, damage to the shock and/or
bike and will void the warranty.
SHOCK TERMINOLOGY
Shock sag: The amount the shock compresses when the rider’s body weight is
applied to the shock while sitting on the bike. Please refer to each bike model’s
shock setup chart to determine correct air pressure and corresponding sag
percentage.
Compression damping: Shim controlled damping system for slow to medium
shaft speeds, controls the resistance felt from the oil damping when compressing
the shock for a firm ride feel, offering greater cornering and braking performance.
Spike Valve: Part of the compression damping system that will dump large
volumes of oil as the system encounters larger, faster bump impacts allowing for
great bump absorption without over producing compression damping, which the
rider feels as a form of hydraulic lock.
Rebound damping: Controls the rate of return of the shock after compression.
Brain Fade: Opens and closes a separate bleed circuit that allows a small amount
of fluid to pass freely by the inertia valve controlled circuit. For the rider, this
adjustment will reduce the firmness of the shock’s platform at ride height.

CAUTION! Be sure to wipe the shock body clean after every ride to prevent wear
and damage to the shock. Failure to follow this caution will void the warranty.
All internal shock maintenance must be performed by an authorized Specialized
Service Center. For a list of service centers, please visit www.specialized.com,
e-mail at [email protected] or call (877) 808-8154.
Wash your shock with soap and water. If you ride in muddy conditions, clean and
service your shock more frequently. Do not use a pressure washer!
When your shock is cycled, grease will purge from the seals. This is normal, it is
not the oil leaking from the shock.
WARRANTY
For warranty provisions, please visit www.specialized.com.
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 schraeder 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.)
NOTE! 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 the stroke of the shock. 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 (shock stroke in mm /
sag percentage). 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.
