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.

BEFORE ASSEMBLING YOUR NEW NITROGEN PRO, MAKE SURE THAT YOU HAVE ALL THE FOLLOWING:
1. Brakes and gears cables and housing set
2: Frameset parts checklist (see p.36)
3: Inspect the frame for cosmetic aspect (scratches, bumps, cracks, paint defect, etc.)
4: For reference, check serial number and write it on p.1
5: All the necessary bolts (refer to Frameset Parts, p.3)
6: For optimal shifting performance, use a dropout alignment gauge to make sure that the drive-side dropout is
straight (p.35)
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.

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.

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.
