Applied technologies

In this chapter, we explain the technologies that the manufacturer uses for this product.

Fusion In-Mold Polycarbonate Shell
The EPS foam is injected into the thin Microshell shell while it is still in the mold (or the "mold", which explains the name) is, instead of forming them separately and stick later. This process was first introduced by Bell and is today the standard for all sophisticated helmets.

Internal Roll Cages
A skeleton of composite material reinforces the helmet and allows for both larger vents, as well as a reduction in weight.

Float Fit ™
Bell's most advanced helm adjustment system combines comfort and safety in an ultra-lightweight design. Float Fit ™ optimizes the fit of the helmet in 2 ways - in terms of head circumference and vertical adjustment. In order to reduce weight and to simplify the operation, the guide arms uniquely enclose the back of the head thanks to the "Float" design. This puts the helmet in an ideal position on the head. Simple, easy and comfortable.

No-Twist tri-glides ™
It depends on the details. Our latest harness system is easy to adjust, keeps the straps flat and prevents them from twisting - which also helps to take a few watts from the wind.
