1. INTRODUCTION
This user manual is specific to your Specialized CruX bicycle. It contains important safety,
performance, and technical information, which you should read before your first ride and keep
for reference. You should also read the entire Specialized Bicycle Owner’s Manual (“Owner’s
Manual”), because it has additional important general information and instructions which you
should follow. If you do not have a copy of the Owner’s Manual, you can download it at no
cost at www.specialized.com, or obtain it from your nearest Authorized Specialized Retailer or
Specialized Rider Care.
Additional safety, performance and service information for specific components such as
seatpost or pedals on your bicycle, or for accessories such as helmets or lights, may also
be available. Make sure that your Authorized Specialized Retailer has given you all the
manufacturers’ literature that was included with your bicycle or accessories. If there is a
difference between the instructions in this manual and the information provided by the
component manufacturer, please refer to your Authorized Specialized Retailer.
When reading this user manual, you will note various important symbols and warnings, which
are explained below:
WARNING! The combination of this symbol and word indicates a potentially
hazardous situation which, if not avoided, could result in serious injury or
death. Many of the Warnings say, “you may lose control and fall.” Because
any fall can result in serious injury or even death, we do not always repeat
the warning of possible injury or death.
CAUTION: The combination of the safety alert symbol and the word CAUTION
indicates a potentially hazardous situation, which, if not avoided, may result
in minor or moderate injury, or is an alert against unsafe practices.
The word CAUTION used without the safety alert symbol indicates a situation
which, if not avoided, could result in serious damage to the bicycle or the
voiding of your warranty.
INFO: This symbol alerts the reader to information which is particularly
important.
GREASE: This symbol means that high quality grease should be applied as
illustrated.
CARBON FRICTION PASTE: This symbol means that carbon friction paste
should be applied as illustrated to increase friction.
TECH TIP: Tech Tips are useful tips and tricks regarding installation and use.
1.1. INTENDED USE
The Specialized CruX bicycles are intended and tested for General Purpose Riding use only
(condition 2). For more information on intended use and structural weight limits for the frame and
components, please refer to the Owner’s Manual.
1.2. WARRANTY
Please refer to the written warranty provisions provided with your bicycle or visit www.
specialized.com. A copy is also available at your Authorized Specialized Retailer.

2. GENERAL NOTES ABOUT ASSEMBLY
This manual is not intended as a comprehensive assembly, use, service, repair or maintenance
guide. Please see your Authorized Specialized Retailer for all service, repairs, or maintenance.
Your Authorized Specialized Retailer may also be able to refer you to classes, clinics, or books
on bicycle use, service, repair, and maintenance.
Tire sizes vary significantly from brand to brand. CEN standards require a minimum of 6
mm of clearance between the frame/fork and the tires. When choosing a wheel and tire
combo, factor in enough clearance for the conditions, setup and wheel flex.
The CruX frames use a 68 mm standard BSA threaded design. Grease the threads. Install
and torque according to the bottom bracket manufacturer’s instructions.
Before installing the bottom bracket and crank, make sure all housings and wires are
routed through the frame.
In order to successfully build the CruX bicycle, it is very important to follow the
order of operations as outlined in this manual. Modifying the order of assembly
will result in a longer build process.
Assembly of the front end of the bicycle is easiest with the rider’s fit already
determined (the steerer tube doesn’t need to be cut at this time, it can stick
out the top of the stem), prior to routing all the housings and wires through the
frame and fork.
To determine fit, it is recommended to use a fit tool. If this is not possible,
perform a basic assembly of the wheels, drivetrain and front-end components,
without the brakes and housings. Once the fit is complete, all the components
will have to be removed in order to route the housings and wires.
WARNING! Due to the high degree of complexity of the CruX, proper assembly
requires a high degree of mechanical expertise, skill, training and specialty tools.
Therefore, it is essential that the assembly, maintenance and troubleshooting be
performed by an Authorized Specialized Retailer.
CAUTION: Do not face the bottom bracket shell! This can prevent proper
installation of the crank. Your Specialized frame does not require any bottom
bracket shell pre-installation preparation, as all surfaces have been precisely
machined to specific tolerances at the factory for proper interface with a
compatible crankset. Please refer to the manufacturer instructions for crank
and bottom bracket installation.
CAUTION: Always use a bottom bracket equipped with a sleeve between the
two cups. Running a bottom bracket without the sleeve can result in housings
and/or wires contacting the bottom bracket spindle, which can result in wear.

3
2.1. TOOLS / TORQUE SPECS
WARNING! Correct tightening force on fasteners (nuts, bolts, screws) on your
bicycle is important for your safety. If too little force is applied, the fastener
may not hold securely. If too much force is applied, the fastener can strip
threads, stretch, deform or break. Either way, incorrect tightening force can
result in component failure, which can cause you to lose control and fall.
Where indicated, ensure that each bolt is torqued to specification. After your
first ride, and consistently thereafter, recheck the tightness of each bolt to
ensure secure attachment of the components.
CAUTION: Ensure that all contact surfaces are clean and bolt threads are
greased or have a threadlocker compound (refer to the instructions for each
bolt) prior to installation.
The following tools are required for installation of this product:
2, 2.5, 3, 4, 5, 6 mm socket-style Allen key bits
Torque wrench
High-quality grease
Cable housing cutters
Carbon assembly compound (fiber paste)
Blue threadlocker
3. GENERAL NOTES ABOUT MAINTENANCE
The CruX is a high performance bicycle. All regular maintenance, troubleshooting, repair,
and parts replacement must be performed by an Authorized Specialized Retailer. For general
information regarding maintenance of your bicycle, please refer to the Owner’s Manual. In
addition, routinely perform a mechanical safety check before each ride, as described in the
Owner’s Manual.
Great care should be taken to not damage carbon fiber or composite material. Any damage
may result in a loss of structural integrity, which may result in a catastrophic failure. This
damage may or may not be visible in inspection. Before each ride, and after any crash,
you should carefully inspect your bicycle for any fraying, gouging, scratches through the
paint, chipping, bending, or any other signs of damage. Do not ride if your bicycle shows
any of these signs. After any crash, and before you ride any further, take your bicycle to an
Authorized Specialized Retailer for a complete inspection.
While riding, listen for any creaks, as a creak can be a sign of a problem with one or more
components. Periodically examine all surfaces in bright sunlight to check for any small
hairline cracks or fatigue at stress points, such as welds, seams, holes, and points of
contact with other parts. If you hear any creaks, see signs of excessive wear, discover any
cracks, no matter how small, or any damage to the bicycle, immediately stop riding the
bicycle and have it inspected by your Authorized Specialized Retailer.
Lifespan and the type and frequency of maintenance depends on many factors, such as
use, rider weight, riding conditions and/or impacts.
Exposure to harsh elements, especially salty air (such as riding near the ocean or in the
winter), can result in galvanic corrosion of components such as the crank spindle and
bolts, which can accelerate wear and shorten the lifespan. Dirt can also accelerate wear
of surfaces and bearings. The surfaces of the bicycle should be cleaned before each ride.
The bicycle should also be maintained regularly by an Authorized Specialized Retailer,
which means it should be cleaned, lubricated, and (partially) disassembled and inspected
for signs of corrosion and/or cracks . If you notice any signs of corrosion or cracking on the
frame or any component, the affected item must be replaced.
Regularly clean and lubricate the drivetrain according to the drivetrain manufacturer’s
instructions.
Do not use a high pressure water spray directly on the bearings. Even water from a garden
hose can penetrate bearing seals and crank interfaces, which can result in increased
bearing and crank wear, which can affect the normal function of the bearings. Use a clean,
damp cloth and bicycle cleaning agents for cleaning.
Do not expose the bicycle to prolonged direct sunlight or excessive heat, such as inside a car
parked in the sun or near a heat source such as a radiator.

WARNING! Failure to follow the instructions in this section may result in damage
to the components on your bicycle and will void your warranty, but, most
importantly, may result in serious personal injury or death. If your bicycle exhibits
any signs of damage, do not use it and immediately bring it to your Authorized
Specialized Retailer for inspection.

WARNING! Do not apply grease to the contact surfaces between the seatpost
and the seat tube. Grease reduces the friction, which is critical to proper
seatpost grip. Specialized recommends the application of carbon assembly
compound (fiber paste), which can increase friction between carbon surfaces.
Please visit your Specialized Authorized Retailer for additional information.
WARNING! Failure to follow the seatpost and frame insertion requirements
(fig. 3) may result in damage to the frame and/or seatpost, which could
cause you to lose control and fall.
WARNING! For general instructions regarding the installation of the seatpost,
refer to the appropriate section in the Owner’s Manual. Riding with an
improperly tightened seatpost can allow the saddle and seatpost to slide down,
which can damage the frame and cause you to lose control and fall.

Both the frame and seatpost have minimum insertion requirements. Additionally, the frame
has a maximum insertion limit to prevent damage to the tire cutout area.
MINIMUM INSERTION: The seatpost must be inserted into the frame deep enough so the
minimum insertion/maximum extension (min/max) mark on the seatpost is not visible. The
frame requires a minimum of 75 mm of insertion.
If the post is at the minimum and the saddle is not at the desired position, the seatpost must be
replaced with a longer or shorter seatpost.
Once the saddle height is determined, torque the seat collar bolt (as seen in fig. 2) to 55

Install the front end (fork, headset, headset spacers, stem, handlebar, wheels) on the frame
then determine the rider’s fit. Do not install more than 35 mm of spacers between the stem
and the headset cover (fig. 2).
Trim the steerer tube so the final cut is 3 mm below the top of the stem (or 3 mm below the
top of the spacer if a 5 mm spacer is used).
Install the steerer tube expander plug. Using a 6 mm Hex key, torque the plug to 45 in-lbf /
5.1 Nm.
When installing the headset for the final assembly, grease the bearings and compression
ring.
Install the headset cover, spacers and stem, followed by the top cap and bolt. Using a 4
mm Hex key, torque the bolt to 44 in-lbf / 5.0 Nm.
Once the bike is fully assembled, adjust the headset, using the front brake to determine if
there’s any headset looseness.
Make sure to determine the appropriate rider stem height before cutting the
steerer tube. Ideally, the steerer tube should be cut 3 mm below the top of the
stem. Alternatively, one optional 5mm solid spacer may be placed above the
stem (fig. 2). In that case, the steerer tube should be cut 3 mm below the 5
mm solid spacer.
WARNING! The stem must be fully supported by the expander plug. Do not
place more than one 5mm solid spacer above the stem. In addition, the
combined height between the stem and optional 5mm spacer (from bottom
of stem to top cap) must not exceed 45mm. This is important if the originally
equipped stem is changed with an aftermarket one. Exceeding 45mm or
placing more than one 5mm solid spacer above the stem may cause the stem
to crush the steerer tube which may result in serious injury or death.
WARNING! The CruX comes with one 5 mm solid spacer and 35 mm of
scalloped spacers. Only the solid spacer should be used above the stem. The
scalloped spacers should only be used below the stem, i.e. between the stem
and the headset cover.
WARNING! Do not apply grease or carbon assembly compound (carbon paste)
between the stem and the steerer tube, and do not twist the stem onto the
steerer tube. This can result in damage to the composite surface, which may
result in a catastrophic failure of the fork, resulting in serious personal injury
or death.
