Assembly Steps
Step A: Handlebar Alignment
Align the handlebar with the front fork. Ensure the handlebar is straight and centered.
Step B: Attaching the Handlebar Stem
Attach the handlebar stem to the fork's steerer tube using the provided bolts. Use a 4mm hex wrench and tighten the bolts securely.
Step C: Handlebar Clamp Adjustment
Ensure the handlebar is correctly positioned in the stem. Check for any improper alignment indicators.
Step D: Securing the Handlebar
Place the handlebar into the stem. Insert and tighten the bolts using a 4mm hex wrench. Ensure the handlebar is centered and straight.
Step E: Final Handlebar Tightening
Tighten the handlebar bolts in a criss-cross pattern. Use a 4mm hex wrench. Rotate each bolt 180 degrees at a time, ensuring even pressure. Check for correct torque specifications.
Step F: Handlebar Orientation Check
Verify the correct orientation of the handlebar clamps. Avoid incorrect positioning.
Step G: Torqueing the Handlebar Bolts
Using a torque wrench, tighten the handlebar bolts to 5.2 Nm. Ensure all bolts are tightened to the correct torque by listening for the clicking sound of the torque wrench.
Step H: Steering System Check
Ensure the steering system rotates freely and is properly aligned. Check for any obstructions or incorrect angles. Tighten the steering column bolts using a 5mm hex wrench and then a 4mm hex wrench, rotating them 180 degrees three times each.
Step J: Final Alignment Check
Confirm the handlebar is perfectly straight and aligned with the front wheel. Check that the steering moves smoothly.
Step K: Final Torqueing
Re-check the torque on the handlebar bolts using the torque wrench, ensuring they are tightened to 5.2 Nm. Confirm by listening for the clicking sound.
Step L: Seat Post Adjustment
Insert the seat post into the frame and adjust to the desired height. Ensure it is securely fastened.
Step M: Seat Post Tightening
Tighten the seat post clamp using a 5mm hex wrench. Rotate the bolt 180 degrees three times to ensure it is secure.
Step N: Saddle Height and Rider Fit
Adjust the saddle height so that the rider can comfortably place their feet flat on the ground while seated. Ensure the seat post is at the correct height for the rider's leg length. Check for proper rider posture and foot placement.
Step O: Saddle Alignment
Ensure the saddle is level and facing forward. Check for any incorrect saddle positioning.
Step P: Final Bike Check
Perform a final inspection of the entire bicycle to ensure all components are securely attached and properly adjusted.
Step Q: Rear Wheel Check
Ensure the rear wheel is properly secured. Use a 15mm box wrench to check the axle nuts.
Step R: Front Wheel Check
Ensure the front wheel is properly secured. Use a 4mm hex wrench to check the axle nuts.
Step S: Pedal Check
Ensure the pedals are securely attached. Use a 5mm hex wrench to check the pedal tightness.
Step T: Tire Inflation
Inflate the tires to the recommended pressure: 35 P.S.I (240KPa) (2.4 BAR). Use a tire pump to achieve the correct pressure.
Step U: Stability Check (Drop Test)
Lift the bicycle approximately 30cm (1 foot) and let it drop. Listen for any clunking or rattling noises that may indicate loose parts.
Step V: Stability Check (Wobble Test)
Gently wobble the bicycle to check for any looseness in the steering or wheels. Listen for any clunking or rattling noises that may indicate loose parts.
