## Long description

The BELL 4FORTY AIR size S (52–56 cm) in Matte Cement is a compact mountain bike (MTB) helmet engineered for trail and enduro riding. It combines a low-profile shell with targeted ventilation and impact protection to meet the demands of daily off-road use. The size S fit is intended for riders with head circumferences between 52 and 56 cm, offering a secure, adjustable retention system and a design that balances coverage and mobility on technical terrain.
Advantages
The helmet delivers a blend of ventilation and protection through a streamlined shell and internal impact-absorbing liner, while maintaining a lightweight feel appropriate for extended rides. An adjustable fit system ensures consistent contact and stability during dynamic movement, and the Matte Cement finish provides a neutral, low-glare appearance suited to a variety of riding kit combinations. The 4FORTY AIR focuses on essential MTB features without unnecessary bulk.
Suitable for
 Trail and enduro mountain biking on singletrack and technical descents
 Daily off-road training rides and bike park laps
 Riders needing a compact helmet in size S (52–56 cm)
 Cyclists who prefer a matte, low-reflective helmet finish
Key specifications
 Fit size: Small, fits head circumference 52–56 cm
 Intended use: Trail and enduro mountain biking
 Shell finish: Matte Cement
 Ventilation: Multiple intake and exhaust ports for airflow management
 Protection: Internal energy-absorbing liner designed for impact mitigation
 Retention: Adjustable rear fit system for secure positioning

How to use
Place the helmet on the head so the front edge sits just above the eyebrows and the rear covers the base of the skull without lifting when you move. Adjust the rear fit dial until the helmet feels snug but not constricting, and position the side straps to form a comfortable Y-shape around each ear. Fasten the chin strap and tighten it so that two fingers can fit between the strap and the chin. Inspect the helmet for visible damage before each ride and replace it after any significant impact according to manufacturer guidance.
Usage recommendations
Use the BELL 4FORTY AIR for trail and enduro sessions where a compact, well-ventilated helmet is preferred. Regularly check straps, buckles and the fit system for wear and functionality, and clean the helmet with mild soap and water. If the helmet has been involved in a crash or shows cracks, dents or compromised liner integrity, replace it immediately to maintain effective protection.
