1. Safety and Standards

The importance of safety

Safety is the top priority when cycling. A good helmet must offer effective protection against impacts, whether falls or collisions with obstacles. It's essential to choose a helmet that meets current safety standards.

Safety standards

Bicycle helmets must comply with European (EN 1078) or American (CPSC) safety standards. These standards guarantee that the helmet has passed rigorous impact resistance and retention tests. Some helmets can also be certified for other activities, such as mountain biking or BMX, offering additional versatility.

2. Construction and materials

Types of construction

There are two main types of construction for bicycle helmets:

• In-Mold: This construction combines a polycarbonate outer shell with EPS (expanded polystyrene) foam on the inside. In-Mold helmets are lightweight and offer good shock absorption, making them ideal for long rides.
• Hardshell: These helmets feature an ABS (acrylonitrile butadiene styrene) or fiberglass outer shell, with EPS foam inside. Hardshell helmets are sturdier and offer better protection against multiple impacts, but are generally heavier.

Materials

The materials used in helmet construction influence durability, weight and comfort. Polycarbonate and ABS shells are commonly used for their impact resistance and light weight. EPS foam is standard for shock absorption. Some top-of-the-range helmets use advanced materials such as Koroyd or MIPS (Multi-directional Impact Protection System), which offer enhanced impact protection.

3. Comfort and fit

Adjustment system

A good bicycle helmet should offer a precise, comfortable fit. Look for models with easy-to-use adjustment systems, such as adjustment knobs or ratchet tightening systems. These systems allow you to adjust the helmet to the shape of your head for optimum fit.

Ventilation

Ventilation is crucial to maintaining a comfortable temperature during outings. Bike helmets should be equipped with effective ventilation systems, with well-placed openings to control air flow. Some models offer active ventilation systems, enabling ventilation to be modulated according to weather conditions and physical exertion.

Lining and padding

The helmet's inner lining must be comfortable and moisture-wicking to prevent excessive perspiration. Look for helmets with removable, washable liners, offering optimum hygiene. The padding should be thick enough to offer good comfort, without compromising ventilation.

4. Specific features

Goggle compatibility

Bike helmets must be compatible with your cycling goggles. Look for models with eyewear attachment systems, such as clips or straps, to prevent the glasses from slipping off. The shape of the helmet should also allow a perfect fit with the glasses, without creating unpleasant pressure points.

Audio system

Some bicycle helmets feature integrated audio systems or are compatible with audio kits. These features enable you to listen to music or communicate with your cycling partners without having to remove your helmet. Make sure that the audio system does not interfere with the helmet's safety and comfort.

Accessories and options

Bike helmets can be fitted with a variety of options and accessories to enhance their functionality. Among the most useful are removable visors to protect against sun and rain, integrated headlamps for night rides, and multiple impact protection systems (MIPS) for added safety.

5. Durability and maintenance

Durability

Durability is an essential criterion for a bicycle helmet. Materials must be resistant to abrasion, impact and the elements. Helmets with ABS or polycarbonate shells offer good durability. Models with fiberglass or carbon reinforcements are even more robust, but generally more expensive.

Maintenance

Good maintenance extends the life of your helmet. The inner lining should be removable and washable to maintain optimum hygiene. Ventilation systems should be cleaned regularly to prevent the build-up of dirt and debris. Store your helmet in a dry place away from direct sunlight to prevent material degradation.

Choosing a bicycle helmet is a crucial decision for advanced cyclists. By taking into account safety, construction, comfort, specific features and durability, you can find the ideal helmet for your outings. Don't forget to check compatibility with your other equipment and to test the helmet in conditions similar to those you'll encounter on your outings. With the right helmet, you'll be able to enjoy every outing to the full, in complete safety and with optimum performance.
