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.
