How to use
To use the helmet, place it level on your head so that it covers your 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 against your head without causing discomfort. Fasten the chin strap securely, ensuring there is enough space to fit two fingers between the strap and your chin. Always check that the helmet does not shift significantly when you move your head before starting your ride.
What to consider before purchase
Measure your head circumference accurately to ensure it falls within the 55-58 cm range.
Verify that the helmet sits comfortably and does not press against your temples.
Ensure the chin strap mechanism is easy for you to operate with one hand.
Usage recommendations
Regularly inspect your helmet for any signs of wear, cracks, or damage to the straps and shell. If the helmet sustains a significant impact, it must be replaced immediately, even if no visible damage is present, to ensure continued safety. Store the helmet in a cool, dry place away from direct sunlight to maintain the integrity of the materials.
