For the warranty to be valid, the bicycle must be fully assembled by an authorized Argon 18 dealer. High end components,
particularly carbon parts, need extra care when assembled. Those components must be installed using a calibered torque
wrench to make sure every bolt is at the right torque setting to prevent damage.
IMPORTANT: No more than 30mm of spacer can be place between the stem and the top cap of the 3D system.
And the use of more than 5mm spacer on top of the stem could void the eciency of the compressor.
These practices will automatically cancel any warranty claim against the manufacturer.

housing starting under the bottom
bracket shell.
3. Install the rear brake cable housing
(see page 8 for details). Use supplied
Jagwire housing (KEB).
Note: For maximum braking performance
it is strongly recommended to use the
non-compressible jagwire KEB housing
(Jagwire 5mmKEB-SL / RCK###).

Remove the 2 cable stopper (on the
head tube and near the seat collar).
Font section: Mesure the necessairy
cable housing to ensure a proper
rotation of the handlebar. Insert the
“KEB” cable housing and the cable
trough the top tube.
Rear section: With a magnet, get the
rear brake cable out of the frame, and
pass it trough the rear cable stopper.

Rear derailler: Pass the cable housing
inside the frame starting at the rear
derailler hanger until it comes out the
top tube.
Front derailler: Remove the cable guide
(9) under the bottom bracket. Pass the
cable housing inside the downtube
until it comes out the top tube.
Add a plastic cap at the end of the
housing, pass the rear derailler cable
inside the housing and x the cable
guide under the bottom bracket with
the 5mm screw (1.5 Nm).
For a Di2 conguration, use the bottom
bracket dedecated cover (10) for
electric shifting.

The Di2 cable routing can be achieve easily using this simple
trick: use a brake cable and a metal cable end to x the Di2
cable. For more information on Shimano Di2 electronic system
installation, go to : http://si.shimano.com.

you use electronic shifting or mecanical
drive train).

NITROGEN 231A/231B: 5. Brake pads spacing
IMPORTANT : If the brake bad spacing is
too thick, the brake arm can rub on the
frame down tube. Make sure the pads
spacing is appropriate.
Adjust brake pads according to the
width of your rims:
- You can congure the brake pads
spacers with 1mm (17h), or 2mm (17i)
depending of the rim width you are
using.
