## Summary description

BELL 4FORTY MIPS is a mountain bike helmet in solid white, size M (55–59 cm), featuring MIPS rotational impact protection for enhanced safety. Designed for trail and all-mountain riding, it offers ventilation, a secure retention system and multi-impact protection elements to reduce rotational forces and improve rider safety during off-road cycling.

## Long description

BELL 4FORTY MIPS MTB helmet in solid white, size M (55–59 cm) is a mountain bike helmet engineered for trail and all-mountain riding. It integrates a multi-impact shell construction with MIPS rotational impact protection to help reduce rotational forces in certain crash scenarios. The helmet balances coverage and ventilation, and includes an adjustable retention system for a secure fit during off-road use.
Advantages
The helmet provides rotational impact mitigation through the integrated MIPS system combined with a multi-impact capable shell, delivering added protection compared with a basic single-impact construction. Ventilation channels are designed to promote airflow on longer climbs and technical descents. An adjustable retention system allows quick size fine-tuning for comfort and stability, while the solid white finish offers a neutral, low-visibility aesthetic that is easy to pair with different kit.
Suitable for
 Trail riding and enduro / all-mountain cycling where additional rotational protection is desired
 Day-long rides that require consistent ventilation and comfort
 Riders seeking a mid-size helmet (55–59 cm) with an adjustable fit system
 Mountain bikers who prefer a straightforward, solid-colour helmet design
When it may not be suitable
This helmet is designed primarily for mountain biking and off-road use; riders who need a road-specific aero helmet or a full-face downhill helmet with chin protection may find it inadequate. Additionally, those outside the 55–59 cm head circumference range will require a different size for proper fit and protection.
Key specifications
 Intended use: Mountain bike / trail / all-mountain
 Size range: Medium fit for 55–59 cm head circumference
 Protection features: MIPS rotational protection and multi-impact shell elements
 Ventilation: Multiple airflow channels for passive cooling
 Fit system: Adjustable retention mechanism for secure fit
 Finish: Solid white color
How to use
Place the helmet level on your head so the front edge sits just above the eyebrows. Adjust the retention system and side straps until the helmet feels snug but not tight; the helmet should not move significantly when you shake your head. Fasten the chin strap and adjust it so you can fit one or two fingers between the strap and your chin. Inspect the helmet for damage before each ride and replace it after any significant impact or when signs of wear compromise protection.
What to consider before purchase
 Measure head circumference to confirm the 55–59 cm medium size is appropriate
 Decide whether MIPS rotational protection and multi-impact shell characteristics match your riding style and risk tolerance
 Check compatibility with any goggles, communication systems, or accessories you plan to use
 Consider alternative sizes or models if you require full-face coverage or road-specific features
Usage recommendations
Use the helmet for trail and all-mountain riding where a balance of ventilation, fit adjustability, and rotational protection is required. Replace the helmet after any significant crash, and follow manufacturer care instructions to maintain the integrity of protective liners and the MIPS system.
