The shape was refined for all-around road performance—ventilated for long climbs but still fast for the flats—and the integrated Float Fit system offers comfort and security with a streamlined fit and an oversized dial that’s easy to adjust with one hand.The Overbrow Ventilation system pulls cool air in through the front and pushes it through an air-channel matrix to reduce overheating. And thanks to the adjustable No-Twist Tri-Glides, the straps stay flat and properly positioned no matter how hard you’re hammering. This model also includes MIPS (Multi-Directional Impact Protection System) for added protection in certain types of impacts.FeaturesFloat Fit™Fusion In-Mold Polycarbonate ShellLightweight Internal Polycarbonate Roll CageLightweight StrapsMIPS®ï¸-EquippedNo-Twist Tri-Glides™Overbrow Ventilation™Reflective Decals (select colors)Sweat Guide™ PaddingWeight: 275 gCertification: CE EN1078, CPSC BicycleTechnologiesMIPS MIPS is a sliding plane system within the helmet designed to slow or prevent the amount of energy that is transmitted to or from the head.Float Fit Bell's most advanced helmet fitting 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. To reduce weight and simplify handling, 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, light and comfortable.IN-Mold In the in-mold construction, the robust polycarbonate outer shell is bonded to it in a single pass during foaming of the impact absorbing EPS inner shell. This makes the helmet even more resistant without any additional weight. This production process also makes it possible to form significantly better ventilation systems and openings. In-Mold helmets are lighter than traditional helmets and have much better ventilation systems.Rol Cage The Roll Cage™ is a reinforcement made of particularly impact-resistant Nylon®, which is embedded directly in the EPS inner foam of Bell's best helmets. It provides extra stability and safety. Casco strada Bell Stratus Mips taglia S (52-56 cm) nero opaco
