Helmets

Size

The size is determined by the circumference of your head as measured about 2.5 cm above your eyebrows. Sizes are listed in cm. Some models have only one size and are adjusted by the sizing wheel.

General sizing parameters for adult helmets:

• S (50 - 54 cm)
• M (54 - 58 cm)
• L (58 - 62 cm)
• XL (62 cm and more).

Helmet types

Road bike

• Better aerodynamics, low weight, and efficient ventilation.
• Can also be used for mountain bikes and rollerblades.

MTB

• Equipped with a removable visor that protects your eyes against the sun and road debris.
• Feature a more robust design and protect the back of the skull.
• Can also be used for road bikes and rollerblades.

BMX/Freeride

• Have a specific design providing maximum protection for downhill rides and rough terrain. Usually protect the head from the sides as well, including the nape of the neck and jaw.
• Structurally they are more closed, have less ventilation, and higher weight.

Fastening

• Dual straps - the first strap goes around your head, while the other is buckled under your chin.
• Sizing wheel - a newer fastening mechanism, controlled by a sizing wheel on the back of the helmet's internal sizing ring. Twisting it in one direction expands the helmet, while twisting it in the opposite tightens it.

Other features

• Insect mesh
• Inner padding - provides greater comfort during long trips.
• Removable interior lining - can be washed in a washing machine.
• Antibacterial protection - contains silver ions, which kill bacteria and reduce unpleasant odour.
• Number of vents - particularly important in long summer trips and children's helmets. A well-ventilated helmet reduces the risk of a heat stroke.
