The lightweight Strale helmet uses a unique design with a system of vents for maximum cooling effect and great aerodynamics. Cool air is brought in through the front tunnels and, thanks to the Venturi effect, pushes the heat away from the head through the rear vents. Safe, comfortable and well ventilated - that's the Strale helmet. The helmet is constructed using state-of-the-art In-Mould Intelligent Fusion technology, the Safe-T Duo system is used for easy one-handed fitting and hypoallergenic padding ensures comfort. Strale Safe-T Duo Road Bike Helmet A style clamping system designed to ensure that the helmet stays firmly on your head. Control disc in the back of the helmet for easy one-handed size adjustment. Being visible is a basic prerequisite for cyclist safety. When riding at night, the rider is much more visible to drivers approaching from behind thanks to the ability to mount an LED light at the back of the helmet. Air shaft system The exceptional design uses a main air tunnel to draw in cold air and together with the side shafts ensures maximum helmet ventilation. Thanks to the Venturi effect, heat is pushed out through the rear vents, providing a great cooling effect. All while maintaining amazing aerodynamics. Hypoallergenic padding The internal padding is the most important factor determining the comfort of the helmet. MET uses only hypoallergenic materials with different widths to match the positioning in the helmet. In-Mould Fusion In-mould construction consists of an outer polycarbonate that is injection moulded at high temperatures into usually grey or black polystyrene. The result is a helmet that offers you the optimum balance between weight, volume and absorption properties. Sizes Weight S - 240 g M - 255 g L - 290 g
