Designed to accommodate electronic, mechanical and hydraulic controls, the PX-Series frame is
engineered to provide seamless integration of all shifting systems, regardless of method or brand.
In order to do so, you will require the parts shown below. Not all parts will be used, depending on
the groupset tted to the bicycle.

Clean chainstay with isopropyl
alcohol and apply chainstay
protector.
Lightly grease Rear Derailleur Hanger
Fixing Nut and install Rear Derailleur
Hanger (DRH-WMN112) nger tight. Final
tightening will be performed after rear
wheel installation.
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).
Do not nal tighten rear derailleur hanger
assembly without rear wheel installed.
Doing so may result in a misaligned
derailleur and poor shifting.
FRAME & FORK PREPARATION
Hold the frame using a secured seatpost only.
Clamping the top tube can damage the frame
and void your warranty.
1. Apply carbon assembly compound to both
frame and seatpost.
2. Insert Seatpost Clamp (SPC-148A) in frame so
it is ush with the top tube.
3. Adjust height and torque to 8Nm maximum.
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.

FORK INSTALLATION
Note: It is recommended that you familiarize
yourself with the steering system before
complete installation, by performing a trial
assembly without hoses or control cables
present.
Fork Insert
1. To prepare fork for the glue in Fork Insert, carefully sand a bevel to
the inside of the end of the circular steerer tube to t the insert.
2. Dry t Fork Insert to check that it is ush with the end of the steerer
tube.
3. Use isopropyl alcohol to clean the inside of the steerer tube and the
outside of the Fork Insert.
4. Fully mix the two-part epoxy and apply to the outer surface of the
Fork Insert with the wooden mixing stick.
5. Slide the Fork Insert into the steerer while rotating it slowly until the
ared end sits ush with the top of the steerer.
6. Wipe away any excess glue from the outside surface of the steerer
tube with the isopropyl alcohol wipe.
7. Set the fork aside and allow it to sit undisturbed for the full curing
period.
Do not attempt to t the fork into a bike prior to
the completion of the full curing period.
NOTE: This diagram is for assembly reference
only. During complete assembly, hoses and
control cables will be present.

1. Check the Stem Steerer Clamp and headset components to make sure there are no sharp or
rough edges on any of the surfaces which could cut or damage the steerer tube. If any rough
edges are detected, have the components repaired (sharp edges removed) or replaced before
proceeding.
2. Press the upper and lower headset bearings into the frame, and insert the fork into the head
tube.
3. Slide the compression ring onto the steerer, and down until it fully seats in the top of the
upper headset bearing. The split in the compression ring must be oriented toward to the left or
right side of the steerer – never towards the front or back.
4. Slide the Stem Steerer Clamp onto the fork steerer oriented as shown. Note the Stem Steerer
Clamp must engage both the fork steerer and the external steerer. Do not use grease on the
fork steerer. The use of Tacx Carbon Assembly Compound™ or equivalent friction paste is
recommended to help secure the Stem Steerer Clamp.
5. Lightly grease the threads of the Preload Fixing Screw, and the Steerer Clamp screws.
6. Place the Stem Cap on top of the Stem Steerer Clamp and insert the greased M6 bolt through
the cap to engage with the star nut. Tighten the bolt only enough to remove all play from the
headset, and ensure that the fork still rotates freely.
7. Tighten the 2 greased Steerer Clamp Screws to the steerer using a torque wrench. Tighten to a
maximum of 5Nm.
8. As a nal check ensure that the fork rotates freely in the head tube without any play or
binding. If any problem is detected, loosen the bolts and perform steps 6) to 7) again.
Do not exceed the maximum torque specication for the stem. Correct tightening force on
fasteners – nuts, bolts, screws – on your bicycle is very important. Too little force, and the
fastener may not hold securely. Too much force, and the fastener can strip threads, stretch,
deform or break. Either way, incorrect tightening force can result in component failure,
which can cause you to loose control and fall.

RISER POST CUTTING INSTRUCTIONS
1. Use a light coloured grease pencil to accurately mark the cut-o location
on the Riser Post. See table below for the exact number based on frame
size.
2. Insert the Riser Post 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; proceed with
cutting the stem steerer (as per Park Tool’s instructions).
4. Carefully le the cut end removing any rough edges.
Achieving the lowest possible stack may require trimming
the Riser Post. If using a cut Riser Post ensure there is always
a minimum of 70mm inserted inside the frame.

The battery for the Shimano Di2 system mounts inside
the down tube using the Internal Battery Mount (MT-BINT)
designed to t this frame. As this is a sealed location, it is
important to test the system prior to nal installation.
Insert a long 5mm hex key* into the lower end
of the holder to work as an insertion tool.
For larger sizes, it may be necessary to install
the battery holder with the aid of a exible
5mm tool, rather than a 5mm hex key. A
piece of brake housing can be used.
*
Pass the battery and holder assembly through
the opening in the bottom bracket shell and
position it, in the down tube, so that the xing
nuts are located over the mounting holes.
Press the two M3 xing nuts
into the holder through the
upper holes. Attach battery
to mount using two zip ties,
and install.
Ensure Loctite 242 is applied to the M3 xing
screws. Pass through the mounting holes to
catch the xing nuts in the battery holder,
tightening only slightly to hold in place.
Remove 5mm hex key. Using 2mm hex key,
tighten xing screws to maximum of 2.5Nm
over the mounting holes.

SEATPOST CUTTING INSTRUCTIONS
If trimming is required, nal 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.
PX Seatpost
Plug (SPP-PX)
1. Ensure that nal saddle height is conrmed and tested.
2. Mark the seatpost cutting line, by tracing the lower edge of the seat tube
on the seatpost.
3. Remove the seatpost.
4. Insert the 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.
5. 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).
Trim excess seatpost no more than 5mm above marked line.
6. Use ne grit sandpaper to carefully remove any fraying or burring
from the cut end. Return to the frame and install PX-Series Seat Post
Plug (SPP-PX).
Cut Line
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 smallest of those two numbers,
subtract 8mm (4mm per side) to determine the
remaining space.
4. With the tire installed and fully inated on your
wheel, measure the widest of the rim or tire
width to ensure that it ts.
Tire/Rim
Dimension
Frame
Clearance
Contact between the tire or rim and the
frame or fork may result in a loss of control
while riding and potentially serious injury.
Failure to follow these guidelines may result
in damage to the frame not covered by
Cervélo Limited Lifetime Warranty.
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.
