Apex Zephyr Helmet Black 58-61cm and 54-56

The Apex Zephyr Helmet Black bicycle helmet combines style and safety perfectly. It's designed to fit heads with a 58-61cm circumference, with an adjustable dial system enables you to adjust the size of the helmet. Built into the dial is an LED light, which should help drivers see you more easily when you're riding on the road.

A detachable peak improves your view, helping to block out the sun's glare on bright days. When it does get too hot, the 11 vents across the helmet will keep you cool.
