The Bell 4Forty MIPS is a trail helmet built for mountain biking and all-day riding, offering premium features at an accessible price. Extended rear coverage adds protection where it matters most, giving you confidence on every descent.

MIPS Evolve integrates the slip plane into the retention system to help reduce rotational forces, keeping the helmet compact, lighter and better ventilated. Combined with the Float Fit system, optimised ventilation and Sweat Guide padding, it stays comfortable and secure across long days on the trail.
