## Long description

The BELL 4Forty Air MIPS MTB Helmet in Sprint Stone is a high-performance head protection solution engineered specifically for trail riding and technical mountain biking. This helmet combines advanced safety features with a lightweight, aerodynamic profile to ensure riders remain protected and comfortable during demanding off-road sessions. By integrating industry-leading impact management technology with a highly ventilated shell, it provides a reliable balance of safety and airflow for enthusiasts tackling diverse terrain.
Advantages
The primary benefit of this helmet is the integrated MIPS technology, which is designed to reduce rotational forces that can result from certain angled impacts. The helmet features an optimized ventilation system that promotes consistent airflow, keeping the rider cool even during intense climbs or warm weather conditions. Its adjustable visor allows for customized coverage, while the moisture-wicking padding manages sweat effectively to maintain comfort throughout long rides. The secure fit system ensures the helmet remains stable on rough trails, providing confidence and peace of mind.
Suitable for
Trail riding and technical mountain biking
All-mountain cycling
Riders seeking enhanced rotational impact protection
Cyclists prioritizing ventilation and comfort on long rides
When it may not be suitable
This helmet is specifically optimized for mountain biking and trail use. It may not be the most suitable choice for specialized road cycling where a more aerodynamic, non-visored profile is preferred, or for high-speed downhill racing that requires full-face protection.
Key specifications
Integrated MIPS rotational impact protection system
Size M (55-59 cm)
Adjustable visor
Sweat-wicking interior padding
Optimized ventilation channels
How to use
To use the helmet, place it level on your head, ensuring it covers the forehead without obstructing your vision. Adjust the rear fit dial until the helmet is snug but comfortable against your scalp. Fasten the chin strap and adjust the side sliders so that the straps form a V-shape just below your ears. Ensure the buckle is securely clicked into place before starting your ride. The visor can be adjusted to your preferred angle to shield against sun or trail debris.
What to consider before purchase
Verify your head circumference to ensure the M size (55-59 cm) is the correct fit
Check compatibility with your preferred riding eyewear
Ensure the helmet style matches your primary riding discipline
Usage recommendations
Always inspect your helmet for signs of wear or damage before every ride. If the helmet sustains a significant impact, it should be replaced immediately, even if no external damage is visible. Store in a cool, dry place away from direct sunlight.
