Troy Lee Designs Grail Helmet

Yes, the Grail is specifically certified for electric bicycle use. It meets the necessary safety standards to handle the higher speeds and potential impact forces associated with e-bike riding.

The visor-free design is primarily an aesthetic choice for a cleaner, more minimalist look. It does not compromise the helmet's structural integrity or safety features, making it just as effective for gravel riding as it is for urban commuting.

The MIPS (Multi-directional Impact Protection System) is integrated into the internal structure of the helmet. It is designed to reduce rotational forces on the brain during certain types of angled impacts, providing an extra layer of protection beyond standard foam liners.

The 14 vents are strategically placed to promote consistent airflow across the scalp. While it provides solid ventilation for commuting and gravel riding, it is designed for versatility rather than the extreme airflow found in dedicated racing helmets.

The helmet utilizes a precision dial retention system located at the back. This allows you to easily tighten or loosen the fit with one hand to ensure the helmet sits securely and comfortably on your head.
