Using this POC Axion Spin Helmet is easy. First, use the 360° size adjustment system to find a snug fit on your head. Make sure the helmet sits evenly and doesn't wobble. Adjust the breakaway peak to the position that suits the weather and your riding conditions. When riding, always ensure the helmet is securely fastened. As for maintenance, clean it regularly with a mild soap and water. Avoid using harsh chemicals as they may damage the helmet's shell. Store it in a cool, dry place when not in use. Check the helmet for any signs of damage, like cracks or dents, before each ride. If you've been in a crash, replace the helmet immediately as its protective capabilities may have been compromised.
