Mountain biking is a demanding sport - compromising on equipment is definitely not a good idea. The 4Forty helmet is made to withstand the pitfalls of trails. Its quality is comparable to helmets that cost twice as much: it has a deep profile that covers the back of the head, is perfectly ventilated, fits perfectly on the head thanks to the Float Fit fastening system and has an adjustable label.
CLAMPING SYSTEM: Float Fit (integration with MIPS for variant with MIPS system)
CONSTRUCTION: In-mold Polycarbonate Shell
VENTILATION: 15 holes, Channeled Ventilation
FEATURES: positionable label, Sweat Guide
SIZES: S (52-56 cm), M (55-59 cm), L (58-62 cm), XL (61-65 cm)
MIPS IS A MOVEMENT
All Bell helmets are designed to absorb as much energy as possible during an impact and meet the applicable European standard: EN 1078. The goal of the new MIPS technology is to eliminate rotational forces that act on the head in the event of a fall. In an impact at any angle, the MIPS system allows the EPS shell of the helmet to rotate independently around the rider's head. Although this movement is only on the order of a few millimeters, we believe that MIPS technology significantly reduces the amount of rotational force that would otherwise be transmitted to the brain.
WHAT IS MIPS (multidirectional Impact Protection System) AND HOW DOES IT WORK?
MIPS is a slippery insert between the EPS shell (helmet body) and the inner linings. In the event of an impact at an angle (for example, when you catch your head on a branch), the EPS shell of the helmet rotates a few millimeters after the MIPS layer, protecting the head and brain from a violent rotational jerk.
