## Long description

BELL 4FORTY size M (55–59 cm) is a mountain bike helmet designed for trail and enduro riding. The helmet combines a lightweight outer shell with an internal EPS impact-absorbing liner and multiple ventilation ports to balance protection, comfort and airflow during extended off-road use. An adjustable retention system and padded straps provide a secure fit for riders who need reliable head protection across varied terrain.
Advantages
The shell construction keeps overall weight low while preserving structural integrity. The internal EPS liner is engineered to absorb and dissipate impact forces, and the strategically placed vents promote continuous airflow to help regulate temperature during climbs and technical sections. The adjustable retention system allows fine-tuning of fit, and the helmet’s design accommodates goggles and other common trail accessories.
Suitable for
 Trail riding on mixed singletrack and forest paths
 Enduro stages and downhill practice
 Recreational off-road cycling and weekend rides
 Commuting on rough or unpaved routes
Key specifications
 Size range: Medium fit for 55–59 cm head circumference
 Shell: lightweight hard outer shell construction
 Liner: internal EPS impact-absorbing foam
 Ventilation: multiple airflow ports for heat dissipation
 Retention: adjustable fit system with micro-adjust dial
 Comfort: padded straps and removable/washable liner pads
 Finish: matte white and black color scheme
How to use
Place the helmet on the head so the front edge sits just above the eyebrows and the rear covers the back of the skull without tilting. Adjust the retention dial until the helmet feels snug but not restrictive; tighten the chin strap so two fingers fit between the strap and the chin, and position the side straps to form a V just under the ears. Regularly inspect the shell and liner for cracks or damage after a fall and replace the helmet if it has been impacted. Clean the helmet with mild soap and water and allow it to dry naturally.
Usage recommendations
Use this helmet for trail and enduro riding where a balance of ventilation, impact protection and lightweight construction is required. Replace the helmet after any significant impact or according to manufacturer guidance, and pair it with appropriate eyewear and protective gear for technical descents.
