FRAME & FORK PREPARATION
910
1. Apply carbon paste to both frame and
seatpost.
2. Insert the seatpost and the Seatpost Clamp
(SPC-0E0S5) fully into frame so it is fully
ush with the top tube.
3. Adjust height and torque to 8Nm maximum.
Hold the frame
using a secured
seatpost only.
Clamping the top tube
can damage the frame
and void your warranty.
1. Lightly grease supplied M4 xing screw. Install
the Threaded Fork Insert (QRI-THD) and xing
screw, tightening only lightly.
2. Without wheel in place, install the axle and
tighten until the ange meets the fork dropout
face, but does not compress the fork blades.
3. Tighten the xing screw to 3Nm.
4. Remove the axle and install wheel. Reinstall
axle and tighten to 12-15Nm.
5. Remove axle and wheel, and re-torque the xing
screw to 3Nm.
Install Front Derailleur
Mount (FDM-0E0), and
ensure xing screws are
torqued to 3Nm.
For 1x systems
replace with the
Front Derailleur
Mount Blanking
Plate (FDM-CVR).
Lightly grease Rear Derailleur Hanger Fixing
Nut and install either Rear Derailleur Hanger
(DRH-WMN112) or Direct Mount Rear
Derailleur Hanger (DRH-SDM) nger tight.
Final tightening will be performed after rear
wheel installation.
In preparation for assembly, pre-form threads
in the Upper Bearing Gap Spacer (FKI-GPSP)
by installing the supplied M3x8mm xing
screws with the fork separate from the frame.
Then remove the screws and Gap Spacer. The
Gap Spacer will be installed on the fork after
installation on the frame, and pre-forming
simplies the process.
Lightly grease interior of the
Tension Rod Bumper (HS-
581) and install onto Tension
Rod (HS-TRxx). Note: "xx"
denotes frame size.
Do not final tighten
rear derailleur hanger
assembly without rear
wheel installed. Doing
so may result in a
misaligned derailleur
and poor shifting.
DRH-SDMDRH-WMN112
Clean the chainstay using isopropyl alcohol. Install the
Chainstay Protector (PRO-CS-508) by removing adhesive
backing, and xing the guard to the frame. The bottom
rearward edge should be approximately 50mm forward
from the back of the rear dropout.

Gap Spacer
1. Apply grease to the bearing
pockets and install the upper
and lower headset bearings
into the frame.
2. Orient the fork perpendicular
to the frame and with the fork
tilted away from the frame at
the top, position the raised
crown area of the fork inside
the lower bearing.
3. Tilt/rotate the top of the fork
into place over the upper
bearing. When positioned
correctly little or no eort
should be required to position
the top of the fork above the
front of the head tube & upper
bearing.
Rotate/slide the fork around
the head tube counter-
clockwise until it is mostly
aligned with the frame, and
sitting slightly o-center
relative to the frame .
4. With the lower bearing mostly
seated in this position, gently slide
the fork laterally and let the crown
settle fully into the lower bearing.
Once fully seated the top of the
fork can be fully aligned above the
upper bearing.
5. Rotate fork perpendicular to frame
and install the Upper Bearing Gap
Spacer. Fasten with the M3x8mm
xing screws, torque to 1Nm
(nger tight).
Take care not to force the fork
top over the head tube by
deviating from these installation
steps or by trying to push-
through interference between
these parts. Improper assembly
can result in damage to the paint
on the frame or fork.

Here are a few t ricks that we have learned along the way that may help with
reinstallation:
Before reinstalling the stem with no spacers:
• Loosen the handlebar xing screws a few turns.
• In order to avoid pinching the rear brake hose during reinstallation of the stem,
simply remove the rear brake caliper from the frame and draw the extra hose
length out, by gently pulling the caliper toward the rear of the bike.
• Carefully reinstall the stem by feeding the extra hose into the frame , and tighten
the stem xing screws (alternating between the three) to 8Nm.
• Reinstall the rear brake caliper by pushing the extra hose into the frame.
• Ensure the hoses are located in the appropriate slot in the bar, and tighten the
handlebar xing bolts to 5Nm.
BEFORE FINAL FITTING
• While the two-piece Stem Spacers allow for addition/removal without re-
cabling the bike, the length of the cables used during rst assembly will dictate
how much adjustment is possible later on.
• After rst assembly it is simpler to remove Stem Spacers (go lower) and trim
the hydraulic brake hose at the brake lever as required.
• Adding spacers after rst assembly (go higher) may require replacement of the
hoses to get the required length.
• Whenever possible, it is best to establish the correct t before performing nal
cabling of the S5.
• It is recommended to include 20mm of additional brake hose length to the
amount required for the nal customer t. Doing so will permit sucient
length for disassembly and service purposes.
Do not attempt to force hydraulic brake hose that
will not slide smoothly into the frame through
the fork/head tube. This may result in the cables
becoming kinked or cracked, and cause a fluid leak
which can result in a loss of brake function and a
risk of serious injury.

1cm
1. Taking care to maintain the minimum required seatpost insertion of 6.5cm and
maximum of 8.5cm, carefully measure and use a light coloured grease pencil
to accurately mark the cut-o location on the seatpost.
2. Insert the SP20 seatpost in the Park Tool SG-7.2 Saw Guide (or equivalent) so
that the cut-o line can be seen clearly through the blade guide in the tool.
3. Using a blade designed specically for cutting carbon composite materials (or
a ne tooth blade with greater than 32 teeth per inch); proceed with cutting the
Seatpost (as per Park Tool’s instructions).
4. Use ne grit sandpaper to carefully remove any fraying or burring from the cut
end. Reposition clamp approximately 10cm from the cut end.
5. With a grease pencil, mark a point 1cm from the cut end on the trailing edge of
the Seatpost, and another 1cm from the back, on the bottom edge. Draw a line
connecting them, forming a 45 degree guideline.
6. Placing the blade of your saw on the grease pencil mark, very carefully
proceed to cut, resulting in a 45 degree chamfer being cut onto the trailing
edge of the Seatpost.
7. Carefully sand the end and after applying carbon assembly compound,
return to the frame.
Note: It is essential that all Cervélo Aero Seatposts have a 45
degree chamfer cut on the rear trailing edge of the post. If trimming
is required after tting, the following method is recommended.
HBP-HB14-EXTMT
SEATPOST CUTTING INSTRUCTIONS COMPATIBLE PARTS - HB14 TRI EXTENSION MOUNT ASSEMBLY
If trimming is required, final length should allow for a
minimum 6.5cm of seatpost remaining in the frame. Failure to
meet this requirement, may result in damage to the frame not
covered by warranty policy, or serious injury to rider.

TIRE/RIM CLEARANCE
Your Cervélo bicycle complies with the ISO 4210-2:4.10.2 standard for tire clearance. In order to comply with these safety standards and
maintain your Limited Lifetime Warranty, a minimum of 4mm of clearance must remain between the tire and any frame element. Due to
the growing complexity of tire and rim interfaces, Cervélo recommends identifying the available space before choosing a tire.
1. Measure the space between the chainstays at
the bottom bracket junction.
2. Measure the space between the seatstays at the
top of the tire.
3. Using the smaller of those two numbers (Frame
Clearance), subtract 8mm (4mm per side) to
determine the maximum Allowable Tire/Rim
Dimension.
4. With the tire installed and fully inated on your
wheel, measure the greater of the rim or tire
width and ensure it is less than the calculated
Allowable Tire/Rim Dimension width to ensure
that it ts.

INTENDED USE OF THE S5 BICYCLE
No one type of bicycle is suited for all purposes. Your retailer can help you
pick the “right tool for the job” and help you understand its limitations.
There are many types of bicycles and many variations within each type.
There are many types of mountain, road, racing, hybrid, touring, cyclocross
and tandem bicycles. There are also bicycles that mix features. For
example, there are road/racing bikes with triple cranks. These bikes have
the low gearing of a touring bike, the quick handling of a racing bike, but
are not well suited for carrying heavy loads on a tour. For that purpose you
want a touring bike.
Within each of type of bicycle, one can optimize for certain purposes. Visit
your bicycle shop and nd someone with expertise in the area that interests
you. Do your own homework. Seemingly small changes such as the choice
of tires can improve or diminish the performance of a bicycle for a certain
purpose.
NOTE: Usage conditions are generalized and evolving. Consult
your retailer or Cervélo Customer Service about how you intend
to use your bike.
NOTE: Cervélo bicycles are tested to a maximum combined
bicycle/rider/luggage weight of 100kg. Components have
different weight limits, and if replaced can alter the maximum
safe bike weight limit. Consult your retailer or Cervélo
Customer Service about what components are appropriate for
your bicycle.
High-Performance Road- Condition 1
Bikes designed for riding on a paved surface where the tires do not lose
ground contact.
Intended To be ridden on paved roads only.
Not Intended For o-road, cyclocross, touring with racks or panniers, or
mounting child seats or trailers.
Trade-O Material use is optimized to deliver both light weight and specic
performance. You must understand that (1) these types of bikes are intended
to give an aggressive racer or competitive cyclist a performance advantage
over a relatively short product life, (2) a less aggressive rider will enjoy longer
frame life, (3) you are choosing light weight (shorter frame life) over more frame
weight and a longer frame life, (4) you are choosing light weight over more dent
resistant or rugged frames that weigh more. All frames that are very light need
frequent inspection.These frames are likely to be damaged or broken in a crash.
They are not designed to take abuse or be a rugged workhorse.
Understand your bike and its intended use. Choosing the wrong bicycle
for your purpose can be hazardous. Using your bike the wrong way is
dangerous.

Correct tightening torque of threaded fasteners is
crucial to your safety. Always tighten fasteners to
the correct torque. In case of a conict between
the instructions in this manual and those
provided by a component manufacturer, consult
with your retailer or with Cervélo Customer
Service for clarication. Fasteners that are too
tight can stretch and deform. Fasteners that are
too loose can move and fatigue. Either mistake
can lead to a sudden failure of the fastener.
Use only a correctly calibrated torque wrench to
tighten critical fasteners on your bike. Carefully
follow the torque wrench manufacturer’s
instructions on how to set and use the tool for
accurate results. Ensure you read all relevant
documentation and have the correct tools prior to
attempting any adjustments yourself.
It is recommended that you permit your retailer to
perform the following adjustments, as they have
the proper tools and experience to ensure it is
done correctly.
Prior to assembling and tightening any bolts,
all threads must be generously greased with a
quality, non-lithium type grease unless the bolt
is pre-coated with Loctite® thread locker. All bolts
should have either grease or Loctite - but never
both. Torque wrenches with scale appropriate
for the particular torque setting are strongly
recommended for tightening all threaded
fasteners.
Cervélo strongly recommends the use of carbon
assembly compound/friction paste for all areas
of clamping to carbon ber, such as the seatpost
to frame, the stem to fork, and the handlebar to
stem joints. Benets to using this paste include
reduced corrosion potential, and a decrease in
required clamping force needed to support a
given load.The paste should be evenly spread on
the carbon surface under the clamped area, and
the applicable bolt tightened as per the following
recommendations.
WARNING: In case of a disagreement
or a conict between the following
list and any supplier literature on
recommended torque values for original
equipment components, please contact
Cervélo Customer Support for review and
clarication of the required torque prior
to installation.
