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 KRYPTON PRO, 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 KRYPTON PRO, 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
IMPORTANT:
The following parts are assembled on the frameset. When assembling the bike, you will need to adjust these parts
according to their torque specications when necessary.

Brakes
Useonlyatmounthydraulicdiscbrakes. The frame and fork are
compatible with either 140mm or 160mm disc rotors. Adapters might be
required, consult brake manufacturer.
• Rear mount thickness: 25mm
Tire Clearance
The biggest tires that can be installed must be no wider than 34mm
(32c) for the rear and front wheel. If fenders are installed, the tires must be
no wider than 30mm (28c).

Handlebar clamp size: Ø31.8mm
No more than 30mm of spacer can be placed between the stem and
the top cap of the 3D system. The headset expander plug must be
placed directly at the same height at the stem steerer clamping, or
else it will void the effi ciency of the compressor. These practices will
automatically cancel any warranty claim against the manufacturer.
Headset cap:
When uninstalling the headset cap, you
needtorstloosentheheadsetcap,
remove the HS cap screw and remove
the fork from the frame. Then you need
to pinch the rear section the headset
cap and lift the rear section upward.
This will release the headset cap from
the frame.

KRYPTON PRO 302A 4. Bike Fitting
Here are the basic bike-tting steps to follow before proceeding with the complete assembly.
Consult your authorized Argon 18 Dealer to assure a proper t that takes into account your personal specications.
STEP 1: Frame Size
• 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.
STEP 2: Saddle Height
• 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).
STEP 3: Stack Height
• 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.
STEP 4: Reach
 •EachKryptonProframesetincludeasizespecic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).

Refer to the supplied 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. 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.
Required minimum SeatPost Cut length = C - (“desired Saddle Height” - A)
- Example: - For a desired Saddle Height of 600mm on a XX-Small Krypton Pro Frame
- The required minimum SeatPost Cut length is: 90 - (600-560) = 50mm

KRYPTON PRO 302A 4.3. Stack Height Adjustment
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proled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 tabs facing
upward. 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).

KRYPTON PRO 302A 4.5. Cutting the Fork’s Steerer Tube
To assemble the Krypton Pro Stem with the Integrated Top Compression
Cap (7.5), the fork’s steerer tube must be cut-to-size.
1.Conrmyourdesiredstackheightandstemheightposition.
Measure twice, cut once!
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-specic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.
Wear respiratory protection, gloves, eye protection and keep skin
covered.
You should also work in a well-ventilated space away from electrical
equipment.Carbonberisconductive;ifairbornecarbonberdustor

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)
*** After Step 2., complete the frame cable routing before continuing with Step 3. Refer to section 6. or 7. ***
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.

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 fi x the Wireless
