Mavic road bike helmets: safety, ventilation and a precise fit

 The best road bike helmets for professional cyclists are those that offer the perfect combination of lightness, ventilation and safety.
Mavic helmets, leaders in this field, are designed using advanced technologies in their construction and architecture, incorporating different densities of expanded polystyrene (EPS).
The adjustment system is among the lightest on the market, and the Autofit non-adjustable chin strap automatically adapts to different head shapes.
Mavic helmets are prized by professionals for their comfort, aerodynamics and impact resistance, making them an ideal choice for cyclists of all levels.

Measure your head circumference (above the eyebrows), then refer to the size guide.
Mavic helmets are available in various sizes, ranging from S to L (and from 51 to 61, covering juniors to adults), to suit all head shapes.
It is important to choose a helmet that fits the shape of your head perfectly, without being too tight or too loose.
Also ensure that the helmet sits correctly on your forehead, with the chin strap properly adjusted. Once you have found the ideal size, you can enjoy optimal comfort and maximum protection on your bike rides.

 The lifespan of a road cycling helmet depends on several factors, such as frequency of use, intensity of rides, and storage and maintenance conditions.
Mavic helmets are designed to last for several years, but it is recommended that you replace them after 5 years from first use, even if they show no visible signs of wear.
This is because the materials used in the manufacture of helmets can degrade over time and through exposure to high temperatures and/or UV light (behind a windscreen, for example), which reduces their ability to absorb impact in the event of an accident. 

It is also important to replace a helmet after a significant impact, even if it does not appear to be damaged, as internal damage may compromise its protective performance. 

The helmet should sit horizontally, low on the forehead (without obstructing your vision). Tighten the rear fastening until it is firmly secure, then adjust the V-shaped straps around your ears. The chin strap should be comfortable but tight enough to prevent the helmet from slipping.

Most road helmets combine an outer shell and an impact-absorbing inner structure (often made of EPS foam), with straps and comfort padding.
Specific features may be added depending on the model: technical padding, anti-rotation systems such as MIPS, or adjustment or self-adjusting mechanisms..

In Europe, bicycle helmets are generally certified to the EN 1078 standard. This standard sets out requirements and tests (impact absorption, retention system, field of vision, marking).
In other markets, different standards may apply (for example, CPSC in the United States).

Because a fall from a bike can result in a blow to the head, even at moderate speeds. A helmet is designed to absorb some of the impact energy and protect your head.
In practice, the most important thing is to wear your helmet every time, ensure it is properly fitted and that it is in good condition.
It remains your best ally for keeping you safe.

Clean with warm water and mild soap, then leave to air dry. Avoid solvents and direct heat. Wash the foam pads if they are removable, and regularly check the condition of the straps and buckle.
You can buy replacement foam pads suitable for your helmet.
