INTENDED USE
The Shiv TT is intended and tested for Road Riding only (Condition 1). For more
information on intended use and structural weight limits, please refer to the
Owner’s Manual.
WARNING! The Specialized carbon components on the Shiv
TT bicycle are designed for a maximum rider weight of 240
lb (109 Kg). Do not ride these components if your weight,
including any gear and accessories you are wearing, exceeds
this weight limit. Failure to follow this warning may result in an
accident, which can cause serious injury or death.
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.
The Shiv TT is compatible with wired or wireless electronic shifting systems
only. Mechanical shifting systems are not compatible.
Inspect the fork, stem, seatpost and seat tube, to ensure that there are
no burrs or sharp edges. Remove any burrs or sharp edges using fine grit
sandpaper.
All edges of the stem in contact with the steerer tube should be rounded
out to eliminate any stress points.
WARNING! Due to the high degree of complexity of the Shiv TT,
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.
WARNING! Many components on the Shiv TT , including,
but not limited to, the seatpost, headset and cable guides,
are proprietary to the Shiv TT . Only use originally supplied
components and hardware at all times. Use of other
components or hardware may compromise the integrity and
strength of the assembly. Shiv TT specific components should
only be used on the Shiv TT and not on other bicycles, even if
they fit. Failure to follow this warning could result in serious
injury or death.
WARNING! Never modify your frame or components in any
way. Do not sand, drill, file, or remove parts. Do not install
incompatible forks or components. An improperly modified
frame, fork, or component, can cause you to lose control and
fall.
In order to successfully build the Shiv TT 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. The following are the recommended routing
instructions for Shimano Di2 wiring on the Shiv TT.
Use the Park IR-1 Internal Cable Routing Kit to simplify
installation of shift wires or cable housings and brake
housings.
We may occasionally issue updates and addendums to this document. Please periodically check www.
specialized.com or contact Rider Care to make sure you have the latest information .

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. The following is a summary of torque

GENERAL NOTES ABOUT MAINTENANCE
The Shiv TT 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 frequency and type of 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, inspected for signs of corrosion and/or cracks and lubricated.
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.
When placing the frame and/or bicycle in a repair stand, clamp the
stand to the seatpost and not the frame. Clamping the frame can cause
damage to the frame that may or may not be visible, which may impair
the structural integrity of the frame.
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.
WARRANTY

• Both the frame and seatpost have minimum insertion requirements. In
addition, the frame has a maximum insertion requirement 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. Both the frame and seatpost require a minimum of
75mm of insertion.
• MAXIMUM INSERTION: The Shiv TT frame has a cutout on the back of the
seat tube. When inserting the seatpost, there should be sufficient space
between the bottom end of the seatpost and the cutout so as to not cause
any structural damage to the frame. The maximum insertion requirement is
185mm.
• Install the derailleurs and drivetrain according to the manufacturer’s
instructions (including exit port plugs).
WARNING! Failure to follow the seatpost and frame insertion
requirements (fig.10) may result in damage to the frame and/
or seatpost, which could cause you to lose control and fall.
The Venge seatpost is compatible with the Shiv TT, and is
available in two lengths (300mm and 390mm). If the 390mm
post is too long, we recommend using the 300mm seatpost.
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.
WARNING! Inspect the seatpost and seat tube to ensure that
there are no burrs or sharp edges. Remove any burrs or sharp
edges using fine grit sandpaper.
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.

EXTENSIONS
MINIMUM INSERTION
FIG. 26: Install the extensions.
• Insert the extension shifter wires in the extensions until they exit the ends of
the extensions.
• Route the extension shifter wires through the extensions (loosening the stack
bolts can help). Depending on the shifters, the wires will either have the exit
the hole at the end of the extensions, or out a side hole.
• Once routed, insert the extensions into the extension sockets.
WARNING! Make sure the extensions are inserted past the MIN
mark etched on the side of the extension sockets.
• Plug the wires into the shifters and install the shifters according to the shifter
manufacturer’s instructions.
• Adjust the angle and insertion depth position of the extensions, then torque
the extension bolts to 22 in-lbf / 2.5 Nm.
