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.

Slide seat post shuttle (3.1.3) into seat post rail
at desired position. Screw seat post chariot
(3.1.1) onto shuttle (make sure shuttle M5 holes
are aligned upwards) with M5x16 (3.1.7) screws
and tighten to 6Nm.
Loosely assemble remaining seat post head as
shown.
Install saddle inserting rails between upper
clamp (3.1.5) and lower clamp (3.1.4). Adjust the
angle, the oset of the saddle using both M5
Hex bolts (3.1.8). Tighten using 8mm wrench.
Note: While the seat post chariot lets you adjust
saddle setback in a wide positioning window,
the lower clamp can additionally be ipped to
change saddle setback by 5.2mm.

ELECTRON PRO 245A: 9.1. Steerer Module Setup Instructions
Steerer Module
(81177)
1. Assemble Steerer Module using bolts provided (2x
front M6x14 + 1x central M6x45). Make sure washer is
placed under central bolt. Grease and tighten all bolts at
9Nm. Use an extended M5 Hex bit or extension to access
central bolt.
2. Assemble the Module Cover using the Button Head
Screw (1x BHCS M6x12) and a 4mm Hex key. Grease the
screw and tighten at 6Nm with a torque wrench.
Note: you might want to temporarily set up the steerer
module in order to t rider, determine stem height
position, and cut line prior to tightening bolts (see
instructions on following page).

± 3mm
3. The design of the steerer module allows it to be cut to length based on
stem height position, similar to a standard fork steerer. You will need to cut the
aluminum steerer as shown (use standard steerer cutting jig).
4. File down and cut end of steerer clean to make sure it is free of burr.
5. Insert stem, align with wheel and compress down using top cap and 8mm Hex
Key.
6. Tighten stem according to manufacturer’s instructions.
7. Install preferred drop bar onto stem as per manufacturer’s instructions.
