For the warranty to be valid, the bicycle
must be fully assembled by an authorized
Argon 18 dealer. High-end components,
such as carbon parts, require extra care
during assembly.
These components must be installed using
a torque wrench to ensure each bolt is at
the specified torque setting to prevent
damage.

etc.)
3. Record serial number on p.4 for reference.
4. Make sure you have all the necessary bolts (refer to
frameset parts, p.8).
5. For optimal shifting performance, use a derailleur alignment gauge to make sure
that the derailleur hanger is straight.

Refer to the adjacent table for details on saddle height and seatpost insertion limits:
i. The correct frame size must be determined according to the saddle height limits.
A. Maximum Saddle Height.
B. Minimum Saddle Height.
ii. Depending on the size of the frame and the desired saddle height, the seatpost might
need to be cut.
If the desired saddle height is lower than value “C”, Calculate the required cutting lenght
“G” as follow:
“G” = “C” – “Desired saddle height “ + 10mm (to allow adjustment)
Example: For a desired saddle height of 650mm on a Small frame, the required minimum
seatpost cut length (G) is:
G = 686 - 650 + 10 = 46 mm
Important: In any case the saddle height can be lower than value “B” .
