GETTING STARTED

Fork

Before fitting and installing your fork, please consult the included 

Cervélo

 Fork Installation manual, and familiarize yourself with the correct assembly procedure. 

Along with the guide, you will find the 

Cervélo

 bond-in compression plug and sleeve, two-part epoxy, and cleaning materials. When cutting to length, 

Cervélo

requires that the Steerer tube is held using the appropriate saw guide for threadless steerer, and cut using a carbon specific blade only. To ensure rider safety, the 
inside of the fork should be properly cleaned before the bond-in compression plug is installed, and the epoxy is allowed to cure.

Derailleur cables

Designed to accommodate electronic, mechanical and hydraulic controls, the S5 frame has been 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 on the following page:

Mechanical

Front and rear derailleur cables should be assembled with the rear housing inserted into the drive-side port of the top tube cable stop, and the front housing in the 
non-drive side cable port (with rocket-adjuster installed). The housing should be long enough that it passed in a smooth arc from the lower back of the bar, over the 
stem cap, and enters the top tube cable stop perpendicular to the top tube. The housing stops in the cable stop, with the cables continuing into the frame though 
the plastic straws provided.

Connect the cables to derailleurs and adjust as per manufacturer's instructions

Route cables into the frame, and out of 
bottom bracket. Ensure cables are not twisted 
together.

Route cables through BB guide. Front cable crosses the valley. 
Feed cables in direction of seat tube and chain stay.

Install chain stay housing stop.

Housing stop is about 8cm farther back, so 
use about 8cm shorter housing than normal.

Route cables out of front derailleur and rear 
dropout exit holes. Snap BB guide into frame.

These instructions and pictures are for assembling the Shimano and Campagnolo electronic shifting systems on the 

Cervélo

 S5, and are intended as a supplement to 

the manufacturer’s installation instructions only. Please refer to www.shimano.com, www.campagnolo.com and www.cervelo.com for additional information.

It is recommended to install the electronic system as a first step when building up a bare frame.

REAR BRAKE

The installation of the rear brake requires the attachment of the S5 brake plate to the caliper, before it can be fitted to the frame.

Install front click-in cable housing stop.

Install caliper to S5 brake plate (size specific) using 
10mm fixing nut as per manufacturer’s specifications. 
Attach S5 brake plate to frame using lightly greased 
M5 fixing screw.  Tighten to maximum 4.5Nm.

Install  rear housing and adjust brake as usual.

For hydraulic brakes, substitute the appropriate 
click-in hose guides. Hydraulic hose guides have a 
5mm through hole.

Route brake cable in and out of the top tube.

Install rear click-in housing stop.

Attach battery to mount using 2 zip ties, and install 
the two M3 fixing nuts into the holder through the 
upper holes.

Apply Loctite 242 to the M3 fixing screws, and pass 
them through the mounting holes so that they catch 
the fixing nuts in the battery holder. Tighten only 
slightly.  Remove 5mm hex key.  Using 2mm hex key, 
tighten fixing screws to maximum of 2.5Nm. 

Insert a long 5mm hex key into the lower end of the 
battery holder to work as insertion tool.  Passing 
the battery and holder through the opening in the 
bottom bracket shell, locate the battery holder so 
that it is inside the down tube, and the fixing nuts are 
positioned over the mounting holes.

REPLACEABLE REAR DERAILLEUR MOUNT

Your S5 utilizes a replaceable rear derailleur mount (DRH-R-2012) for simplified service 
and extended frame life. In the unfortunate event that replacement is required, 

Cervélo

recommends authentic Cerv

é

lo replacement parts be used.

Inspect the frame for damage and ensure the frame is clear of any debris. Apply Loctite 242 
to the fixing screws, and tighten the screws equally to a maximum of 2.5Nm. Install the wheel 
in the frame, and use a Derailleur Alignment Gauge to align the hanger parallel to the wheel.

INSTALLING INTERNAL BATTERY

The battery for your Shimano Di2 system mounts inside the downtube using a holder (DI-BM-INT-S5D) designed to fit this frame.  
Because this is a sealed location, it is important to test the system and install the battery unit, prior to the bottom bracket
