Assembly Instructions
Step A: Attach Handlebar Stem to Fork
Insert the handlebar stem into the fork's steerer tube. Follow the numbered sequence indicated in the diagram (1, then 2).
Step B: Attach Handlebar to Stem
Align the handlebar with the stem. Secure the handlebar using four bolts (indicated by 'x4'). Use a 4mm hex wrench for tightening.
Step C: Check Handlebar Alignment
Ensure the handlebar is perfectly straight and aligned with the front wheel. The diagram shows a correct alignment (indicated by a checkmark) and an incorrect alignment (indicated by a cross).
✔️ Correct alignment: Handlebar is straight and parallel to the front wheel.
❌ Incorrect alignment: Handlebar is turned.
A product information sticker is shown with model and serial number details.
Step D: Secure Handlebar Clamp
Tighten the bolts on the handlebar clamp. Follow the numbered sequence (0, 1, 2) and ensure the clamp is properly secured.
? Caution: Read safety warnings in the owner's manual.
Step E: Initial Stem Bolt Tightening
Using a 4mm hex wrench, tighten the stem bolts in a specific sequence. Rotate each bolt 180 degrees in the order 1, 2, 3, 4. This ensures even pressure.
? Sequence: 1 -> 2 -> 3 -> 4, each rotated 180 degrees.
Diagram shows incorrect clamp orientations (indicated by crosses).
Step F: Check Handlebar Clamp Tightness
Visually inspect the handlebar clamp to ensure it is properly seated and tightened. The diagram shows correct and incorrect tightening methods (indicated by checkmark and cross).
Step G: Final Stem Bolt Tightening with Torque Wrench
Repeat the tightening sequence from Step E. Use a torque wrench set to 5.2 Nm. Tighten bolts until the torque wrench makes a clicking sound, ensuring correct torque is applied.
Tighten bolts in the sequence 1, 2, 3, 4, applying 5.2 Nm torque to each.
Step H: Headset Rotation Check
Check the headset for smooth rotation. Perform a 360-degree rotation check. Then, perform a 180-degree rotation check for the stem bolts, repeating three times for each bolt.
Use a 5mm hex wrench for the 360-degree rotation check and a 4mm hex wrench for the 180-degree stem bolt checks.
Step J: Final Handlebar Alignment Check
With the bike upright, check that the handlebar is perfectly straight and aligned with the front wheel. The diagram shows a correct alignment (checkmark) and an incorrect alignment (cross).
Step K: Final Stem Bolt Tightening
Repeat the stem bolt tightening sequence using the torque wrench set to 5.2 Nm. Ensure all bolts are tightened to the correct torque by listening for clicking sounds.
Tighten bolts in sequence 2 and 3 (referring to the diagram's numbering), applying 180 degrees of rotation.
Step L: Attach Seat Post
Insert the seat post into the frame. Follow the numbered sequence (1, 2) indicated in the diagram.
Step M: Tighten Seat Post Clamp
Using a 5mm hex wrench, tighten the seat post clamp. Rotate the bolt 180 degrees three times (180°x3) to ensure a secure fit.
Step N: Adjust Seat Height and Rider Fit
Adjust the seat height so that the rider can comfortably place both feet flat on the ground while seated. The diagram shows correct rider fit (checkmark) and incorrect fit (cross).
Correct fit: Rider's feet are flat on the ground.
Incorrect fit: Rider's toes are touching the ground, or feet are not flat.
Step O: Check Seat Tightness
Ensure the seat is securely fastened. The diagram shows an incorrect seat angle (indicated by a cross).
Use a torque wrench for final tightening, with a maximum torque of 8 Nm.
Step P: Prepare for Checks
Flip the bike over onto its handlebars and seat for easier access to wheels and pedals.
Step Q: Check Rear Wheel Tightness
Check the rear wheel for tightness. Use a 15mm box wrench. Ensure the wheel is secure by checking the indicated points.
Step R: Check Front Wheel Tightness
Check the front wheel for tightness. Use a 4mm hex wrench. Ensure the wheel is secure by checking the indicated points.
Step S: Check Pedal Tightness
Check the pedals for tightness. Use a 5mm hex wrench. Ensure pedals are securely fastened.
Step T: Tire Inflation
Inflate the tires to the recommended pressure: 35 PSI (240 kPa) (2.4 BAR). A tire pump is shown.
Step U: Post-Assembly Check (Drop Test)
After assembly, check for loose parts by listening for clunking or rattling noises. Drop the bike from a height of 30cm (1 foot) and listen for any unusual sounds.
Step V: Post-Assembly Check (Tilt Test)
Check for loose parts by listening for clunking or rattling noises. Tilt the bike and listen for any unusual sounds.
