How to use
To use the helmet, place it level on your head so that it covers the forehead without obstructing your vision. Use the adjustment dial located at the back of the helmet to tighten or loosen the internal harness until it fits snugly but comfortably. Fasten the chin strap securely, ensuring that the buckle clicks into place and the straps form a V-shape around your ears. Always check that the helmet does not wobble or slide before beginning your ride.
What to consider before purchase
Verify your head circumference measurement before ordering to ensure the 55-58 cm range is appropriate.
Ensure the helmet is compatible with any additional accessories like cycling glasses.
Check that the chin strap is adjusted to allow for comfortable breathing while remaining secure.
Usage recommendations
Regularly inspect the helmet for any signs of wear or damage, especially after an impact. Keep the helmet clean by wiping it with a damp cloth and mild soap, avoiding harsh chemicals that could degrade the protective materials. Store in a cool, dry place away from direct sunlight when not in use.
