1. Safety and Standards

The importance of safety

Safety is the top priority when mountain biking. A good helmet must offer effective protection against impacts, whether from falls or collisions with natural obstacles such as rocks and trees. It's essential to choose a helmet that meets current safety standards.

Safety standards

Mountain bike 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 BMX or mountaineering, offering additional versatility.

2. Types of mountain bike helmets

In-Mold helmets

In-Mold helmets combine a polycarbonate outer shell with EPS (expanded polystyrene) foam on the inside. They are lightweight and offer good shock absorption, making them ideal for long outings and competitions.

• Advantages: Lightweight, good ventilation, effective shock absorption.
• Disadvantages: Less robust than Hardshell helmets.

Hardshell helmets

Hardshell helmets feature an ABS (acrylonitrile butadiene styrene) or fiberglass outer shell, with EPS foam inside. They are more robust and offer better protection against multiple impacts, but are generally heavier.

• Advantages: Sturdiness, durability, increased protection.
• Disadvantages: Higher weight, sometimes less effective ventilation.

Full-face helmets

Full-face helmets offer complete head protection, including face and jaw. They are ideal for more extreme mountain biking disciplines such as DH and freeride.

• Advantages: Maximum protection, enhanced safety for extreme disciplines.
• Disadvantages: Higher weight, limited ventilation, less comfort on long climbs.

3. Comfort and fit

Adjustment system

A good mountain bike 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. Mountain 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

Visor

The visor is an important feature of mountain bike helmets, offering protection against sun, rain and mud splashes. Look for models with adjustable or removable visors for maximum adaptability to light and terrain conditions.

Multiple Impact Protection System (MIPS)

MIPS (Multi-directional Impact Protection System) is an advanced technology that offers additional protection against oblique impacts. Helmets equipped with MIPS are designed to reduce the rotational forces exerted on the brain during an impact, offering enhanced safety.

Compatibility with goggles and masks

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

5. Durability and care

Materials

The durability of a mountain bike helmet depends on the materials used in its construction. 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, which offers better ventilation and enhanced shock absorption.

Care

Good care extends the life of your mountain bike helmet. The inner liner 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 mountain bike helmet is a crucial decision for advanced riders. By taking into account safety, helmet types, comfort, specific features and durability, you can find the ideal helmet for your mountain adventures. 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 descent and ascent to the full, in complete safety and with optimum performance.
