Setup, Compatibility & Care
To set up your Giro Register II, loosen the rear dial completely, place the helmet level on your head, and tighten until it is snug but comfortable. The straps should form a 'V' shape just below your ears with no slack. To clean, use only mild soap and water with a soft, lint-free cloth; avoid harsh chemicals or solvents that can degrade the structural integrity of the shell. Periodically inspect the retention system for debris to ensure the dial continues to turn smoothly. If you prefer a sleeker look for high-speed road riding, simply unclip the visor and store it in a cool, dry place.
