BELL 4Forty MIPSMountain Bike Helmet

Sturdy Design with Fusion In-Molding

Bell's Fusion In-Molding technology combines the helmet's outer shell with the EPS foam liner. This process creates a sturdier helmet, enhancing protection and durability.

Multi-directional Impact Protection System (MIPS)

Equipped with MIPS, this helmet features a leading slip-plane technology designed to reduce rotational forces during certain impacts. The integrated float fit system ensures a minimalist and lightweight fit, with an easy-to-turn rubber dial for precise adjustments.

No-Twist Tri-Glides & Sweat Guide

Our quick-adjust fasteners, No-Twist Tri-Glides, help keep straps flat and properly positioned. The Sweat Guide pad design efficiently pulls moisture away from the brow pad and eyewear, ensuring optimal comfort during prolonged use.

GoggleGuide Adjustable Visor System

This adaptable visor system allows the helmet to work seamlessly with both goggles and glasses. Whether the visor is attached or not, it accommodates a variety of headwear, enhancing versatility and comfort.
