Zefal Z-Eye mirror
Z eye is a mirror that can be easily mounted on most cycling helmets thanks to its Velcro fastening. The advantage is its very low weight (22 g) and it does not weigh down the handlebars.
Thanks to the long stem with an adjustable tip, this mirror allows you to adjust the angle of the mirror according to its position to see what is happening behind you and improve your safety on the bike.
