3. การติดตั้งและการประกอบ

Proper helmet fit is crucial for maximum protection and comfort. Follow these steps to ensure your Lennon helmet is correctly adjusted:

1. วัดหัวของคุณ: Use a flexible measuring tape to measure the circumference of your head, just above your eyebrows. Refer to the sizing chart below to determine your appropriate helmet size. If you are between sizes, it is generally recommended to size down for a snug fit.
2. ตำแหน่งเริ่มต้น: Place the helmet squarely on your head. It should sit level, covering your forehead without tilting back or forward.
3. Adjust the ErgoKnob-2 System: Locate the ErgoKnob-2 dial at the back of the helmet. Turn the dial clockwise to tighten the internal retention system until the helmet feels snug and secure, but not uncomfortably tight. The helmet should not move excessively when you shake your head.
4. ปรับสายรัด: The helmet features adjustable nylon straps. Ensure the straps form a 'V' shape just below your ears. Adjust the sliders to achieve this position.
5. Secure the Chin Buckle: Fasten the chin buckle. Tighten the strap so that it is snug under your chin, allowing only one or two fingers to fit between the strap and your chin. The buckle should not rest directly on your jawbone.
6. Check Visor Attachment: The removable visor can be attached or detached as needed. Ensure it is securely fastened if you choose to use it.
