How to choose your bike helmet?

Certification is mandatory: the CE EN 1078 standard guarantees a minimum level of protection. The size is measured by head circumference; a well-fitted helmet stays in place without moving or compressing, with an adjustment dial. Depending on the activity, a road helmet is aerodynamic and lightweight, while an MTB helmet covers more of the rear and adds a visor. Ventilation (number of vents) is important in hot weather. The

Frequently asked questions

How to choose the size of your bike helmet?

Measure the head circumference above the eyebrows and compare it to the brand's size guide. The helmet must fit firmly without pressure points, be adjusted with the dial, and not slip when you move your head.

Road helmet or MTB helmet, what's the difference?

The road helmet prioritizes lightweight design and aerodynamics with large vents; the MTB helmet covers more of the back of the skull and adds a visor against the sun and branches. Choose according to your activity.

What is MIPS technology? MIPS is an inner hard shell that slides slightly during an oblique impact, reducing the rotational forces transmitted to the brain. It is an additional protection against certain injuries, complementing the outer shell.
