Bell 4Forty MIPS MTB Helmet

With the 4Forty MIPS, Bell has developed a high-end MTB helmet designed for disciplines such as trail, all-mountain and enduro cycling, offering superior protection whilst ensuring a high level of comfort. Indeed, it features generous ventilation, with the Sweat Guide system that channels sweat to the sides to prevent droplets from falling in front of your face and impairing your vision. The Float Fit system allows you to adjust the helmet to your head shape using an ergonomic dial located at the back of the helmet.

With the Bell 4Forty, you get extended rear coverage, a full-shell design, an adjustable visor and integrated MIPS protection. The MIPS system helps reduce rotational forces during an impact, providing a level of protection that exceeds the required standards. Its design is compatible with MTB goggles.
