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. These components must be installed using a calibrated torque
wrench to make sure every bolt is at the right torque setting to prevent damage.

To remove the 3D bearing holder, insert the Park Tool
RT-1 and then tap it carefully until the spacer comes out.
1
STEP
Inspect the bike’s head tube for any sharp edges and
apply a small amount of grease.
2
STEP
For the 25mm and 15mm setups, lightly grease the
bottom section of the 3D bearing holder (6) and insert
the plastic sleeve (7).
3
STEP
Position the headset inside the head tube. Place
the top 3D assembly with the headset bearing inside
(this will prevent the sleeve from getting damaged).
Add the compression ring on top of the bearing, then
add the press t 3D system tool and softly press down
the assembly until it bottoms out using a Bearing Cup
Press (Park Tool HHP-2). Then, insert the bottom
bearing (5), compression ring (4) micro spacers (3) and
top cap (2), slide the fork and stem and measure the
steerer length needed.
For the 0mm setup , do not use the plastic sleeve.
Install the 3D bearing holder (6) with grease applied
directly inside the frame.
4
STEP
First, you must assess which setup suits your needs:
25mm, 15mm or 0mm.

NITROGEN PRO: 4. Stem/Handlebar Installation
1. Choose the desired stem length, bolt, and spacer
needed (refer to the Product Matrix chart on p.X) – note
that the bolt comes pre-coated with Loctite. In the event
of assembling and disassembling, one drop of blue
Loctite (#242 or #243) must be applied on the bolt
threads.

10
NITROGEN PRO: 4. Stem/Handlebar Installation
2. Place the elastic cover on the stem and the
spacer with the Argon 18 logo facing up.
3. Place the handlebar upside down on a clean
rag.
4. With the correct spacer and stem length
using a torque wrench, a ratchet extension,
and a 6mm bit thread the bolt and spacer up
to 40Nm.
5. For easier handling and to prevent damage
to the handlebar we recommend holding it
down rmly while tightening.
40Nm
IMPORTANT:
If the appropriate torque (40Nm)
is not reached and if Loctite is not
applied the handlebar could loosen.
Argon 18 cannot be held accountable
if this is not measured.

NITROGEN PRO: 4. Stem/Handlebar Installation
Place the handlebar on the fork and secure the stem/combo
with the two side bolts to 5Nm.
5Nm

2-3mm
Note: When cutting the fork, allow 2mm or 3mm of additional
space between the compressor cap and the fork in order to
obtain sucient compression of the headset.

1. Install the brake hood to the desired
height and make a mark with a white pen.
2. Lower the shifter assembly.
Electronic Shifting
Important: Always pass the electronic cables before the brake housing; the opposite would make it very dicult to get the
electronic cables through after the brake housing.

3. Fish two cables inside the
handlebar on each side.
4. Select the length of necessary
housing and pass both at the
same time.

5. Pass the brake and gear cables
in the shifter body.
6. Connect cables to housing and
put the levers back to the white
mark on the handlebar.

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