Using the Cinettica Velocita Road Helmet is easy. First, adjust the dial retention system at the back to get a snug fit on your head. Make sure it's not too tight or too loose. When you're cycling, the 23 ventilation ports will keep you cool, so you can focus on the road. Remember to always wear the helmet correctly on your head, covering the top and sides. As for maintenance, use a mild soap and water to clean the helmet regularly. Don't use harsh chemicals as they might damage the helmet. Store it in a cool, dry place when not in use. Also, check the helmet for any signs of damage before each ride, and if you notice any cracks or significant wear, it's time to replace it.
