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 torque wrench to
make sure every bolt is at the right torque setting to prevent damage.

BEFORE ASSEMBLING YOUR NEW MAKE SURE THAT YOU HAVE ALL THE FOLLOWING:
1. Frameset parts checklist (see Frameset Parts’ SKU and Description p.31-34)
2. All the necessary bolts (refer to Frameset Parts’ SKU and Description, p.31-34)
WHEN ASSEMBLING YOUR NEW MAKE SURE YOU FOLLOW THIS PROCEDURE:
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. For optimal shifting performance, use a dropout alignment gauge to make sure that the drive-side dropout is straight

Consult your authorized Argon 18 Dealer to assure a proper t that takes into account your personal specications.
• Using the Sizing Chart (p.6), determine the required frame size based on your saddle height measurement. Where two frame sizes
are suggested, you can choose depending on your prefered stack, reach and stand-over clearance.
• The seat post might need to be cut-to-size depending on your required saddle height. Refer to Min/Max Seat Post Insertion
instructions (p.7).
• Using the Sizing Chart’s Stack and Reach columns (p.6), determine the required 3D system headset size (0mm, 15mm or 30mm)
based on your recommended handlebar position.
• Each Krypton Pro / Krypton GF-IST frameset include a size specic stem:
• If the handlebar reach needs to be adjusted to acheive your
required position, the other stem lengths are available separately.
Refer to the Annex A. Stem Swap Kits instructions (p.35).

A. Minimum Saddle Height
D. Maximum Saddle Height
ii. Depending on the size of the frame and the desired saddle height, the SeatPost might need to be cut.
B. Maximal insertion depth in the Frame’s SeatTube.
C. Required SeatPost cut length to be able to adjust the Saddle Height at the Minimum position.
- Adjust the SeatPost cut length in accordance with your desired Saddle Height.
- Example: - For a desired Saddle Height of 600mm on a XX-Small Krypton Pro/ GF-IST Frame
- The required minimum SeatPost Cut length is: 90 - (600-560) = 50mm

Note: Validate the required Stack Height before
proceeding with the cable routing.
• A total of 60mm of stack adjustment is possible.
• Using the Sizing Chart’s Stack and Reach columns
(p.6), determine the required 3D system headset
size (0mm, 15mm or 30mm) based on your
recommended handlebar position.
• 30mm of proled spacers are provided to ne-
tune your position:
(2x) Spacer 5mm (7.7)
(2x) Spacer 10mm (7.8)
1. Spacers must be installed with the
This feature ensure proper alignement with
the stem and between each spacer.
2. Open and slide-on the required spacers over the
front side of the steerer. Integrated tabs also guide
the spacers on the steerer tube’s front rib.
3. Twist-lock each spacer over the steerer tube
and stack them up between the headset Stack
Compressor (a.) and the Stem’s 1st Spacer (7.3).

The Krypton Pro / Krypton GF-IST comes with two
dierent Stem Caps:
for a slick integration:
• Proled Top Compression Cap (7.5)
• Flat Head Screw M5x25mm (7.6)
to keep an
extra length of fork steerer tube until your t is
conrmed.
• Flat eccentric compressor cap* (a.)
• Flat Head Screw M5x50mm* (b.)
• Eccentric Top Spacer (7.9)
*parts of the Argon18 HeadSet No.30/Kit2 (4.4)

To assemble the Krypton Pro / Krypton GF-IST Stem with the Integrated
Top Compression Cap (7.5), the fork’s steerer tube must be cut-to-size.
1. Conrm your desired stack height and stem height position.
2. Mark the top-back-end of the stem’s carbon body (7.1).
3. Mark the cut line 3-4mm lower than the stem’s top-back-end mark.
4. Cut the fork’s steerer tube using a standard steerer tube cutting jig
and a carbon-specic blade.
5. File down the cut end of the steerer to make sure it is free of burr.
HEALTH & SAFETY WARNING
The carbon bers can easily become a ne dust during cutting or
mechanical nishing and can then be released into the surrounding
atmosphere. These micro bers if uncontrolled have a potential to stick
into human skin or the mucous membranes causing irritation.
You should also work in a well-ventilated space away from electrical
equipment. Carbon ber is conductive; if airborne carbon ber dust or
o-cuts penetrate into electrical switches or equipment, short circuits or
electric shock may occur.
When cutting carbon ber composite, minimise dust or particulate
generation by:
• wet processing of the material;
• using non-powered hand tool.
Steps of assembly
1. Insert the headset plastic sleeve into the top on the headtube. (apply grease)
2. Insert the required headset column, 0, 15 or 30mm, in the headset plastic sleeve. (apply grease)
3. Insert bottom bearing on the fork.
4. Slide the fork in the head tube of the frame.
5.
Install top bearing in the headset column. (apply grease)
6. Install conical compressor ring.
7. Install stack compressor.
8. Apply grease on the headset seal to avoid any noise.
9. Install the corresponding headset cap to complete the assembly.
10. Fix the cap with the M4 at head screw.

Like on almost all Argon 18 bikes you will benet of the 3D system, on the
Krypton Pro / GF-IST you can benet of 3 positions: 0mm, 15mm and 30mm.

1. Select the correct rear derailleur hanger depending on the type of derailleur
that you have.
a. Direct mount
b. Regular mount
2. Make sure to align the rear derailleur hanger.
3. Use Derailleur Hanger Alignment Gauge like Park Tool Item #DAG-2.

Depending of the type of assembly, you will
have to select the correct parts.
Tip: No matter the type of assembly you will
choose, always pass the brake housing rst
starting from the back of the bike to the front.
1. With the rear brake housing coming from
the back of the bike, guide the end of the
housing through the top of the head tube
opening.
2. Use the brake housing to insert the foam
liner into the downtube.
3. Guide the Di2 cable coming from the
shifters through the top of the head tube and
out of the rectangular opening of the console.
4. Guide the Di2 cable coming from the
derailleurs into the downtube and out of the
rectangular opening of the console.
5. Place the Di2 O-Ring around the Shimano
EW-RS910 junction box.
6. Connect the shifters and derailleurs Di2
cables to the Shimano EW-RS910 junction
box.
7. Clip the Shimano EW-RS910 junction box
on the console cap.
8. Fix the console cap to the downtube of the
frame with the screws.
For Wireless groupset, simply x the Wireless
Console Cover to the downtube of the frame
with the screws.
15
Use the square hole to connect all the wires
to the junction box.
Insert the junction box in the hole.
Insert the BB cover in the square hole until it clicks.
