Bell Stratus MIPS
The Bell Stratus MIPS helmet is built on the same design principles as the pro-level Z20 helmet. Stratus combines light aero efficiency with comfort technologies.
The shape of the helmet was chosen for great road performance - the ventilation is great for long climbs, but also for fast straights - and the integrated Float Fit system offers comfort and protection with an increase wheel for easy adjustment of the helmet size with one hand. The Overbrow ventilation system pushes cold air from the front of the helmet through air channels in the helmet, reducing overheating. And thanks to the adjustable No-Twist Tri-Glides straps, the helmet stays properly positioned on your head regardless of how hard you pedal.
Manufacturer Bell managed to integrate the MIPS system into the fastening system - fewer layers, lower weight, smaller helmet profile. The shell is composed of two layers. The one closer to the head has a lower density, is softer, and can thus absorb smaller impacts. The more distant one is, on the other hand, harder.
All Bell helmets are designed to absorb as much energy as possible in the event of an impact and comply with the applicable European standard: EN 1078. The new MIPS technology aims to eliminate the 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. Nevertheless, this movement is only within a few millimeters.
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 a branch with your head), the EPS shell of the helmet rotates a few millimeters after the MIPS layer, protecting the head and brain from a violent rotational jerk.
