BELL 4FORTY Integrated MIPS mountain bike helmet — size L (58–62 cm), matte gloss cement

The BELL 4FORTY Integrated MIPS mountain bike helmet in size L (58–62 cm) with a matte gloss cement finish combines multi-impact shell construction and Integrated MIPS technology to address both linear and rotational forces in a crash. Designed for trail and all-mountain riding, the helmet offers a balance of protection, ventilation and fit adjustability. The low-profile shape and integrated visor provide coverage and glare control without compromising head movement or sightlines on technical terrain.

Advantages

Integrated MIPS is built into the helmet to help reduce rotational forces transmitted to the head during oblique impacts. The multi-impact shell construction improves durability for repeated use in off-road environments. Ventilation channels move air through the helmet to help manage temperature on longer rides, while the adjustable fit system and sizing range (58–62 cm) allow a precise, stable fit for riders who require a large size. The included visor is adjustable to accommodate goggles or to improve sun protection on variable trails.

How to use

Select the correct size by measuring head circumference at the widest point above the eyebrows. Place the helmet level on the head, then tighten the adjustable fit system until the helmet sits securely without excessive movement. Adjust the chin strap so it fits snugly under the jaw with the side straps forming a V just below each ear. Use the visor adjustment to set angle and clearance for goggles or sun protection. Inspect the helmet regularly for damage and replace it after significant impact or if shell integrity is compromised.

Usage recommendations

Use the BELL 4FORTY Integrated MIPS for trail and all-mountain riding where multi-impact durability and rotational-impact mitigation are priorities. For optimal protection, ensure a correct fit and replace the helmet after any crash that affects its structure. Pair with properly fitted goggles or eyewear and clean the helmet according to the manufacturer’s care instructions to maintain performance.
