Step-by-Step Assembly

1. Attach Stem & Handlebars:

1. Remove the protective cap from the stem wedge.
2. Take off the Stem Plug and loosen the Stem Bolt with a 6mm Allen or 13mm wrench.
3. Insert the stem into the headtube, ensuring the Minimum Insertion Line is below the headset’s top nut.
4. Align the stem and handlebar with the front wheel.
5. Tighten the Stem Bolt and reinsert the Stem Plug.
6. Ensure smooth rotation of the headset and a tight top nut.
7. Loosen the 6mm Binder Bolt and adjust the handlebar to a 45-degree angle.
8. Retighten the Binder Bolt to secure the handlebar in place.

1. Install Front Wheel:
1. Remove the tension adjusting nut and one spring, then slide the quick release skewer through the hub. For disc brakes, insert the skewer from the side with the rotor. Replace the spring and nut.
2. If your bike has rim brakes, disengage them for more clearance between the tire and brake pads.
3. Insert the wheel into the dropouts, ensuring the quick release lever is on the left.
4. Hold the lever open and tighten the tension adjusting nut until it's snug against the fork dropout.
5. Push the wheel firmly into the fork slots, center the rim, and move the quick release lever into the closed position.
6. The lever should be parallel to the fork and curved toward the wheel. Apply enough force so it leaves an imprint on your hand.

2. Attach Pedals:

   • Screw the right pedal into the right crank arm (clockwise) and the left pedal into the left crank arm (counterclockwise).
   • Tighten using a wrench.
