4. Setup and Adjustment
Proper fit is essential for helmet safety and comfort. Follow these steps to ensure your helmet is correctly adjusted.
4.1. Measuring Head Circumference
Before adjusting, measure your head circumference to confirm it falls within the helmet's recommended range of 54-62 cm.
- Use a flexible measuring tape.
- Wrap the tape around your head, just above your eyebrows and ears.
- Note the measurement. If it's between 54-62 cm, the helmet should fit.
4.2. Adjusting the Fit
- Positioning: Place the helmet squarely on your head. It should sit level, covering your forehead. The front edge should be no more than two finger-widths above your eyebrows.
- Dial System: Turn the adjustable dial at the back of the helmet clockwise to tighten the fit, or counter-clockwise to loosen it. Adjust until the helmet feels snug but comfortable, without excessive pressure points. The helmet should not move freely when you shake your head.
- Chin Straps: Fasten the quick-release buckle under your chin. Adjust the side straps so that they form a 'V' shape just below your ears. The chin strap should be snug against your throat, allowing only one or two fingers to fit between the strap and your chin.
- Final Check: With the straps fastened, try to roll the helmet forward and backward. It should not move significantly. If it does, re-adjust the dial and straps.

5. Operation and Usage
Once your helmet is properly fitted, you are ready for your ride. Always wear your helmet when cycling to protect against head injuries.
- Ventilation: The helmet features 18 vents designed to circulate air, keeping your head cool and dry during rides.
- Lightweight Design: The ultra-lightweight construction (approximately 253g) minimizes strain on your neck and head, even during extended use.

6. Maintenance
Regular maintenance helps prolong the life of your helmet and ensures hygiene.
- Cleaning the Helmet: Use only mild soap and water to clean the helmet's exterior and interior. Avoid harsh chemicals, abrasive cleaners, or solvents, as these can damage the helmet's materials.
- Cleaning Inner Pads: The inner padding is removable for easy cleaning. Gently detach the pads, hand wash them with mild soap and water, rinse thoroughly, and allow them to air dry completely before reattaching.
- Storage: Store the helmet in a cool, dry place away from direct sunlight and extreme temperatures. Avoid storing it in a hot car, as excessive heat can damage the EPS liner.
- Inspection: Periodically inspect the helmet for any signs of damage, such as cracks in the shell or foam, frayed straps, or malfunctioning buckles. If any damage is found, replace the helmet immediately.

7. Troubleshooting
If you encounter issues with your helmet, refer to the following common solutions:
- Helmet feels loose or shifts: Re-adjust the rear dial system and chin straps. Ensure the helmet is positioned correctly on your head.
- Helmet feels too tight or causes pressure points: Loosen the rear dial system. Check if the inner pads are correctly positioned. If discomfort persists, the helmet size may not be suitable for your head shape.
- Chin strap is uncomfortable: Ensure the 'V' shape of the side straps is correctly positioned below your ears. Adjust the chin strap length so it is snug but not constricting. The chin strap includes a pad for comfort.
- Visor detaches easily: Ensure the visor tabs are fully engaged in the helmet slots. Press firmly until you hear a click.
