2. Safety Information
Always prioritize safety when using this helmet. Please read and understand the following guidelines:
- This helmet is designed for cycling and similar activities. It is not intended for motor sports or other activities where a different type of helmet is required.
- Ensure the helmet fits snugly and comfortably. An improperly fitted helmet may not provide adequate protection.
- Always fasten the chin strap securely. The strap should be tight enough to prevent the helmet from moving freely, but not so tight as to cause discomfort.
- Inspect the helmet regularly for any signs of damage, such as cracks, dents, or frayed straps. If damage is found, replace the helmet immediately.
- Do not modify the helmet in any way. Modifications can compromise its protective capabilities.
- Clean the helmet only with mild soap and water. Harsh chemicals can damage the helmet's materials.
- Replace the helmet after any significant impact, even if visible damage is not apparent. The internal structure may be compromised.

4. Setup and Adjustment
Proper helmet fit is crucial for safety. Follow these steps to ensure a correct fit:
- Choose the Correct Size: This helmet is available in size XS (46-51 cm head circumference). Measure the user's head circumference to ensure it falls within this range.
- Position the Helmet: Place the helmet squarely on the head, covering the forehead. It should sit level, not tilted back or forward.
- Adjust the Retention System: Use the dial or slider at the back of the helmet to tighten or loosen the internal retention system. Adjust until the helmet feels snug but comfortable, without excessive pressure points. The helmet should not move significantly when the head is shaken.
- Adjust the Side Straps: The side straps should form a "V" shape just below the ears. Adjust the sliders on the straps to achieve this position.
- Fasten the Chin Strap: Buckle the chin strap. Tighten the strap until it is snug under the chin. You should be able to fit one or two fingers between the strap and the chin, but no more.
- Check for Movement: With the chin strap fastened, try to push the helmet from side to side and front to back. It should not move more than an inch in any direction. If it does, readjust the retention system and straps.
- Visor Attachment (if detached): Align the visor's attachment points with the corresponding slots on the helmet and firmly press until it clicks into place.
- Rear Light Installation: The rear light is designed to be easily removable and attachable. Ensure it is securely clicked into its designated slot at the back of the helmet.
