4.1 Helmet Fit Adjustment
A proper fit is crucial for safety and comfort. The helmet features a 360° dial fit retention system and adjustable straps.
- Place the helmet on your head. It should sit level and cover your forehead.
- Adjust the dial at the back of the helmet (pull out to adjust, push in to secure) until the helmet feels snug but comfortable, without excessive pressure points.
- Fasten the chin strap buckle. Adjust the straps so they form a 'V' shape under your ears. The strap should be tight enough that the helmet does not move more than an inch in any direction when you shake your head.
The helmet is available in two sizes:
- Medium: 54–58 cm (21.26–22.83 inches)
- Large: 57–61 cm (22.83–24.06 inches)
