Exceptionally ventilated with its 31 holes, and completely streamlined thanks to its Aero shell, the helmet the one is also designed to be able to place the glasses on the top if you do not need during the race, all this without compromise to safety, thanks to the safety QR code and LED designed by bubbles. The helmet the one also has a winter lining for use throughout the year and a removable visor to turn it into helmet mountain bike.
