To use the Rockbros LK-99, place the helmet on your head so that it sits level and covers your forehead. Adjust the rear retention system to ensure a snug but comfortable fit against your scalp. Once the position is correct, bring the magnetic buckle together under your chin until it clicks securely into place. Adjust the side straps so they form a V-shape around your ears, ensuring there is no slack in the webbing.

Measure your head circumference accurately to ensure it falls within the 58-62 cm range
Verify that the helmet style matches your specific type of cycling
Check that the magnetic buckle mechanism is compatible with your personal preference
For optimal safety, always inspect the helmet for any signs of damage or wear before each ride. Ensure the straps are tightened correctly and the visor is adjusted to your preferred angle to maintain clear visibility on the trail.
