R5-CX TORQUE SPECIFICATIONS
Component
Torque(Nm)
Notes
Frame
Bottom bracket - threaded - T47
50 Nm
Clean & grease the BB shell threads inside the frame. Grease the outside threads of the BB cups. Thread both sides of the
BB cups into the frame - noting that the right side cup is reverse threaded. Using a torque wrench and the appropriate
adaptor, tighten both sides to the specified torque until they are flush with the frame.
Rear derailleur fixing nut (disc brake)
12 to 15 Nm
Finger tight prior to rear wheel installation, final torque to approximate torque using open ended wrench.
Removable FDM / FDM blanking plate
3 Nm
Lightly grease the fixing screws.
Water bottle cage fixing screws
2 to 3 Nm
Lightly grease the fixing screws.
Correct tightening torque of threaded fasteners is
crucial to your safety. Always tighten fasteners to
the correct torque. In case of a conflict between
the instructions in this manual and those
provided by a component manufacturer, consult
with your retailer or with Cervélo Customer
Service for clarification. 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 fiber, such as the seatpost
to frame, the stem to fork, and the handlebar to
stem joints. Benefits 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 conflict between the following
list and any supplier literature on
recommended torque values for original
equipment components, please contact
Cervélo Customer Support for review and
clarification of the required torque prior
to installation.
Component
Torque(Nm)
Notes
Fork
Fork steerer compression plug
8 Nm
Lightly grease the fixing screw and tighten to the recommended torque.
Fork dropout insert
3 Nm
Lightly grease screw, install finger tight on NDS fork dropout. Install the axle (no wheel), and tighten until the axle flange
meets the fork dropout - then tighten the fixing screw to recommended torque. Remove the axle, install the axle & wheel
to recommended torque, then remove. Re-torque the fixing screw to recommended torque
Stem
Stem to fork steerer tube
5 Nm
Lightly coat the fork steerer at the stem clamping interface with carbon assembly compound. Tighten the stem fixing
screws evenly & alternately to the recommended torque using a torque wrench.
Stem to carbon handlebar
6 Nm
Coat the stem/handlebar clamping surfaces with carbon assembly compound. Tighten the faceplate fixing screws in a start
pattern to recommended maximum torque using a torque wrench.
Handlebar
Brake/shift levers (to handlebar)
6 to 8 Nm
Refer to manufacturer’s instructions for installation of brake/shift levers.
Accessory mount - front
2 Nm
Lightly grease the fixing screws.
Seatpost Clamp (frame to seatpost)
D-shape collar
6 Nm
Use carbon assembly compound between the seatpost and the frame.
Secondary D-shape collar
3 Nm
Saddle (seatpost head bolts) – SP24 D-shape carbon
2 bolt head
8 to 9 Nm
Ensure Loctite 242 is used on both bolts (1 is pre-applied).
Wheels
Cervélo aero thru-axle / Cervélo aero thru-
axle with removable handle
12 to 15 Nm
Requires the use of a 6mm allen key type wrench or Removable handle.
Other
Pedals
30 to 35 Nm
Refer to manufacturer's instructions.
