Every detail of the Propero 4 was created with our equation for speed in mind. Aerodynamics + Ventilation + Lightweight = Fast.\u003c\/p\u003e\n\u003cp\u003eAERODYNAMICS: With extensive testing in CFD and in our Win Tunnel, aerodynamics were at the forefront of the Propero 4 development. We took the aerodynamic leading edge from the S-Works Evade 3 and pulled it directly into the Propero 4—which helped it to be four watts, or 15 seconds over 40km, faster than our S-Works Prevail 3.\u003c\/p\u003e\n\u003cp\u003eVENTILATION: Drawing inspiration from our world-renowned S-Works Prevail 3, our goal was not merely to replicate but to elevate. Ventilation became a focal point in our quest for a well-balanced, aerodynamic, and ventilated helmet. We incorporated the rear-end design language of the S-Works Prevail 3 and introduced small 2mm offset micro-channels that create turbulence in the airflow throughout the helmet to help create a continuous, refreshing flow of air.\u003c\/p\u003e\n\u003cp\u003eATTENTION TO DETAIL: Beyond just aerodynamics and ventilation, the Propero 4 represents meticulous attention to detail. We went the extra mile by incorporating cutting-edge technologies from our S-Works level helmets, like MIPS technology for confidence, and a fit system designed to deliver all-day comfort. The Propero 4 doesn't just meet expectations, it redefines them.\u003c\/p\u003e\n\u003cp\u003eFor helmets sold in the U.S. and Canada: Complies with U.S. CPSC Safety Standard for Bicycle Helmets for Persons Age 5 and Older.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"bulletPoints_Wrapper\"\u003e\n\u003cul class=\"bullet_points\"\u003e\n\u003cli class=\"bullet_item\"\u003eMips Evolve Solution is a low-friction layer that allows a sliding motion of 10 to 15mm in all directions.
