It’s been a while since road helmets offered much in the way of genuine innovation, so the release of Bell’s new Zephyr might be something to get excited about.
Where most use a polycarbonate shell to house a single-density EPS liner, the Zephyr’s EPS is dual-density, essentially two shells nestled one inside the other.
‘We’ve called this Progressive Layering,’ says Bell’s Sean Coffey.
‘It creates a structure for absorbing a broad spectrum of impacts – regular EPS for severe impact protection, over lower-density EPS that reduces transmitted forces at lower speeds.’
What’s more, the two densities vary in thickness based on Bell’s crash research data on where different types of crash are most likely to impact the helmet.
Bell has backed up the Zephyr’s unique shell with additional security in the form of an integrated MIPS liner in its Float Fit Race retention system.
MIPS, available in several brands’ helmets but never before integrated, is a plastic insert that moves independently of the shell to reduce twisting forces on the skull and neck in the event of an impact.
