INTRODUCTION

Congratulations on your purchase and welcome to the nest line of suspension

products available!

Your bike is equipped with an Specialized AFR fork. Please read this manual in its

entirety for proper setup and service before riding. Please contact Specialized at

(877) 808-8154 for further information or questions, and visit the Specialized Bicycle

Components website at www.specialized.com for periodic updates.

Please read the following warnings. 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.

Make sure that you review and understand the warnings, instructions, and content of

your bicycle manuals.

SERVICE AND MODIFICATIONS

As a rst point of contact for all warranty or service issues, please refer to your

local Specialized Authorized Dealer. All internal fork maintenance must be performed

by an Authorized Service Center. Please visit www.specialized.com for a list of

Specialized Authorized Dealers, which is the point of contact for sending product to

the Authorized Service Center.

Technological advances have made frames and forks more complex, and the pace of

innovation is increasing. It is impossible for this manual or accompanying manuals to

provide all of the information required to properly repair and/or maintain your fork. In

order to help minimize the chances of an injury, it is critical to have work performed by

an Authorized Service Center.

Do not modify your fork or bicycle. Any modications, non-authorized replacement

parts or improper service will void the warranty and can cause damage to the fork unit

and/or frame, which can cause injury or death.

Proper maintenance is critical to the optimal performance and lifespan of the fork.

Please follow the service schedule recommended in this manual. If your fork ever

makes any unusual noises or loses air/oil, stop riding immediately and have the fork

inspected by your local Specialized Authorized Dealer or Authorized Service Center.

Specialized forks are pressurized with an air charge and require special tools to

recharge. The charged section does not need to be opened to perform any cleaning

or lubricating. Because of explosive force, do not open the charged section of the

fork. Attempting to open the charged section of the fork is dangerous and will void

the warranty.

Service on Specialized forks requires special knowledge and tools. Specialized

recommends that all service and repairs be performed by an Authorized Service

Center.

Never modify your fork or frame in any way. Do not sand, drill, ll, or remove parts.

Do not install incompatible aftermarket suspension parts. Riding with a damaged,

broken, malfunctioning or improperly modied frame or fork, can cause you to lose

control and fall.

Specialized forks are only for use on designated Specialized bikes. Do not use the

E100/S90/S120 fork on any other bike. Use of these forks on any non-recommended

bikes can result in poor performance, damage to the fork and/or bike and will void

the warranty.

TERMINOLOGY

FORK SAG: The amount the fork compresses when the rider’s body weight is applied

to the fork while sitting on the bike. Please refer to each bike model’s fork 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 fork

for a rm ride feel, offering greater cornering and braking performance.

BRAIN FADE: Opens and closes a separate bleed circuit that allows a small amount of

uid to pass freely by the inertia valve-controlled circuit. For the rider, this adjustment

will reduce the rmness of the shock’s platform at ride height.

REBOUND DAMPING: Controls the rate of return of the fork after compression.

MAINTENANCE

Maintenance Schedule Every

ride

Every 50

hours

Every 150

hours or

yearly

Set sag (check air pressure) 

Wipe seals and stanchions clean 

Lower leg service 

Send to Service Center for

inspection and oil change 

Wipe the fork legs/seals clean after every ride to prevent wear and damage to the

fork. Failure to follow this caution will void the warranty.

Wash your fork with soap and water. If you ride in muddy conditions, clean and service your

fork more frequently. Do not use a pressure washer!

Inspect the brakes, quick-release and headset before each ride to ensure proper

tightness. Please refer to your Bicycle Owner’s manual for further information.

When your fork is cycled, grease will purge from the seals. This is normal; it is not

the oil leaking from the fork. Thin oil lines on the fork stanchion are a good sign and

means your seals are well lubricated, which reduces wear.

WARRANTY

For warranty provisions, please visit www.specialized.com.

INSTALLATION

E100/S90/S120 forks with carbon steerer tubes are specically designed for the

Epic, Era, Sare and Stumpjumper carbon OEM frames with a 1 1/2” (52mm) lower

bearing and a 1 1/8” (42mm) upper bearing. Each steerer tube is already cut to t the

specic frame size it was paired with.

In the event that the steerer tube needs to be cut down further or any maintenance

needs to be done to the fork, please read the following instructions. If you have any

doubt regarding your mechanical ability and/or installation of this product, visit your

Specialized Authorized Dealer. Specialized recommends that the stem be installed on

the fork using a torque wrench, with the service performed by a qualied mechanic.

Recommended torques in this guide are specic for this Specialized product. Consult

the owners manual for the mating component’s recommended torque. Always use

the lower torque recommendation.

PREPARING THE COMPONENTS

Inspect the fork and stem to ensure that there are no burrs or sharp edges that can

damage the surface in contact with each other. Remove any burrs or sharp edges using

ne grit sandpaper. All edges in contact with the steerer tube should be rounded out

to eliminate any stress points.

Burrs and sharp edges can damage the carbon and alloy surfaces of the components.

Any deep scratches or gouges in the stem or fork can weaken the components

resulting in failure, causing serious personal injury or death.

NOTE: Specialized recommends only external slotted clamp style stems. Internal wedge clamp

style stems can damage the steerer tube if improperly installed (Fig. 1).

PRE-INSTALLING THE FORK

The lower bearing race is permanently pre-installed at the factory. Apply a small 1.

amount of grease to the lower bearing race surface. Avoid getting grease on the

stem interface region of the steerer tube.

Install the bearings in the head tube, with a light coat of grease on the bearing 2.

surfaces. The bearings are friction t and can be installed by hand.

Place the fork in the frame, followed by the headset compression ring, headset top 3.

cap and the desired height of carbon cone and/or headset spacers.

NOTE: Do not install more than 40mm (1.5”) stack height of headset spacers. Exceeding this

limit can compromise the strength of the steerer tube (Fig. 2).

NOTE: Clean the stem interface surface of the steerer tube (above the headset spacers) with

isopropyl alcohol or a similar type of degreaser before installing the stem.

Pre-install the stem (do not apply a high torque without the 48mm Long Expander 4.

Plug installed).

NOTE: Unless the desired stem height is already determined, it is recommended that the

pre-installation of the fork and stem be done with the maximum allowed stack height (40mm)

to allow the greatest range of adjustability. Spacers can be placed above or below the stem

to adjust your position. Once a more precise stem height is determined, a second cut can

be made to eliminate any spacers that may have been placed above the stem to achieve the

desired position.

CUTTING THE FORK STEERER TUBE

Once the initial stem height is 1.

achieved, make a mark on the steerer

tube at the top of the stem. Place the

cutting line 3mm below the mark to

allow for the space needed for the

1mm lip of the expander plug. The

end result is 2mm of space. (Fig. 2).

Wrap the area where you intend to cut 2.

the fork with several layers of masking

tape. This will limit fraying of the

bers, resulting in a cleaner cut. Once

you’ve wrapped the layers of tape, determine the precise location of the desired cut

with a pen mark on the tape. To avoid fraying the composite bers, it is recommended

that a carbide grit toothless saw blade be used. A ne tooth (36 teeth) saw blade is

also acceptable. Double check all measurements to make sure the steerer tube will not

be cut too short. It’s easier to measure twice than to buy a new fork.

NOTE: It is very important that the steerer tube is cut straight. For best results, use a steerer

tube cutting guide tool.

Once the steerer tube is cut to the desired length, remove all burrs at the top of the 3.

steerer tube by rounding out the edge with emery paper or a ne grit sand paper.

Only sand the edge, not clamping surface! Wipe off all excess dust. Be sure not to

breathe carbon dust!

For additional information on carbon ber preparation, please visit the tech section

at www.specialized.com.

INSTALLING THE FORK

Install the 48mm Long Expander Plug (Fig.2). Recommended 1.

torque is 100 in-lbf (11.3 N-m).

The E100/S90/S120 steerer tube requires the use of the RED

(22.5mm O.D.) Specialized 48mm Long Expander Plug (Fig.

2) supplied with the fork. Do not use a star nut, as it can

damage the inside surface of the steerer tube. Damage to

the steerer tube can result in failure, causing serious personal

injury or death.

Place the fork back into the head tube and clean the stem 2.

interface of the steerer tube with isopropyl alcohol.

Place the desired amount of headset spacers to achieve 3.

proper stem height, followed by the stem and the top preload

cap.

NOTE: Do not twist the stem onto the steerer tube. This can result in

damage to the surface, which can render the fork unsafe.

Install the disc brake and brake housing guide on the fork. 4.

Make sure the brake housing routing doesn’t touch the tire

when the fork is fully compressed and that it doesn’t interfere

with the controls on the handlebar when rotated. Do not

overtighten the bolts. Refer to the disc brake manufacturer’s

owner’s manual for recommended torque specications.

Fork install steps continued on next page.

Install the front wheel and adjust the brake to allow the rotor to spin freely.5.

Adjust the headset to eliminate any free play, make sure that the fork rotates freely. 6.

Align the stem with the fork. Tighten the stem’s upper and lower steerer clamp

bolts in an alternating pattern. Increase torque in 5 in-lbf (0.56 N-m) increments.

Recommended torque applied to the steerer tube is 75 in-lbf (8.5 N-m). Refer to your

stem owner’s manual for specic torque spec recommendations for the stem bolts.

Damage to composite is difcult to visually identify. If the external composite surface

is dented, frayed, gouged, deeply scratched, fractured, chipped or otherwise

damaged, the component should be replaced. If a fork has suffered a crash or impact,

even if no damage is visible, Specialized or an Authorized Dealer should inspect the

product.

SHOCK PUMP

Specialized offers a shock pump, to add or release

air pressure from your Specialized fork. The Fox

shock pump is also recommended. Follow the steps

below:

Remove the air cap knob from the top of the right 1.

fork leg (Fig.3).

Thread the pump’s valve chuck onto the fork’s 2.

Schrader valve (holding the rebound knob so it

doesn’t turn) until pressure registers on the pump

gauge. Do not over tighten the valve chuck. If

there’s no pressure in the fork, no pressure will

Stroke the pump until you’ve reached the desired pressure (see air chart for pressure 3.

ranges). Pressure can be decreased by depressing the release valve button on the

pump body.

When the valve chuck is removed, air pressure will be released. This air is NOT from

the fork. It’s leftover air from the pump hose. When the pump is reattached to the

valve, pressure in the fork will decrease to ll the pump hose. This will lower pressure

approximately 10 PSI (i.e., a fork set at 100 PSI will show approximately 90 PSI when

the pump’s hose is re-installed on the fork, as the hose is relled by pressure in the

fork).

Fork pressure range is 40 to 125 PSI. Do not exceed 125 PSI. Exceeding the

recommended limit can result in damage to the fork.

Avoid lowering pressure too far and bottoming out too often and too hard, which can

also result in fork damage.

NOTE: Air pressures and rebound/compression settings are suggested recommendations only

and provide a starting point for the rider. Adjust for preference/riding style.

SETUP

SETTING AIR PRESSURE AND SAG

Setting the air pressure is crucial to getting the

best performance from your fork. To achieve proper

suspension balance, set the rear shock pressure

before setting the fork pressure. The air chart on

the previous page is designed to get you in the

approximate sag range.

Use a high-pressure shock pump to add air. Sag 1.

is based on a % of stroke of the fork. Set sag

according to the chart as a starting point, then

adjust for preference, terrain and riding technique.

Wrap a zip tie around the stanchion. Push the zip 2.

tie down to the seal, then gently sit on the saddle

without bouncing (apply rider weight only to the bike) to compress the fork and

displace the zip tie, then measure the distance between the fork seal and the zip tie

(sag). The rider should be in full ride gear and sitting in a normal riding position when

setting sag.

To maximize performance, monitor travel for the rst few rides. The goal is to reach 3.

90-100% of travel a few times during a ride without harsh bottoming. If full travel is

not being reached on occasion during a normal ride, lower pressure until it does.

ADJUSTING REBOUND

The red knob (top of right leg) controls the

rebound damping, the rate at which the fork returns

after the fork has been compressed.

Turn the knob clockwise for slower rebound 

(slower speeds, bigger hits).

Turn the knob counter-clockwise for faster 

rebound (higher speeds, small bumps) and more

traction.

ADJUSTING COMPRESSION (BRAIN FADE)

The blue knob (bottom of right leg) adjusts compression

(Brain Fade), which helps control cornering and braking

stability, as well as control fork bottom-out.

Turn the knob clockwise for a rmer ride. Full clockwise is 

the maximum damping setting.

Turn the knob counter-clockwise for a softer, suppler 

setting.
