Using the Axion Race Mips bike helmet is easy. Just place it on your head and adjust the straps to fit snugly. Make sure it sits level on your head and covers your temples and the back of your head properly. When riding, the helmet will keep you cool due to its ventilation system. For maintenance, use a mild soap and water to clean the exterior and the interior padding. Let it air - dry completely before using it again. Always check the helmet for any signs of damage after a crash or if it has been dropped. If you notice any cracks, dents, or other issues, replace the helmet immediately. Also, avoid exposing the helmet to extreme heat or direct sunlight for long periods as it may affect its performance.
