Specialized Propero 4 Road Cycling Helmet

The all-new Specialized Propero 4 Road Cycling Helmet brings the aero advantages of the S-Works Evade 3 together with the ventilation of S-Works Prevail 3, all with the comfort and confidence Specialized helmets are famous for, earning the highest 5-Star Virginia Tech helmet rating. Every detail of the Propero 4 was created with speed in mind.

Aerodynamics + Ventilation + Lightweight = Fast. AERODYNAMICS: With extensive testing in CFD and in the Specialized Win Tunnel, aerodynamics were at the forefront of the Propero 4 development.

Specialized took the aerodynamic leading edge from the S-Works Evade 3 and pulled it directly into the Propero 4which helped it to be four watts, or 15 seconds over 40km, faster than the S-Works Prevail 3. VENTILATION: Drawing inspiration from the world-renowned S-Works Prevail 3, the goal was not merely to replicate but to elevate.

Ventilation became a focal point in Specializeds quest for a well-balanced, aerodynamic, and ventilated helmet. They 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.

ATTENTION TO DETAIL: Beyond just aerodynamics and ventilation, the Propero 4 represents meticulous attention to detail. Specialized went the extra mile by incorporating cutting-edge technologies from S-Works level helmets, like MIPS technology for confidence, and a fit system designed to deliver all-day comfort.

The Propero 4 doesnt just meet expectations it redefines them. Features Mips Evolve Solution is a low-friction layer that allows a sliding motion of 10 to 15mm in all directions.

Studies indicate that this reduces some of the rotational forces transmitted to the brain during angled impacts. Propero 4 earned the highest 5-Star Virginia Tech Helmet Rating from internationally renowned Virginia Polytechnic Institute and State University.

FS3 Fit System amp Occipital Base Adjustment optimizes comfort by personalizing fit to individual head shape, and helmet angle can be adjusted for compatibility with glasses. Adjustable Tri-Fix web splitter combined with thin 10mm webbing for increased comfort.

Dedicated sunglass storage maintains a secure fit and keeps eyewear out of the way when needed. Micro Channeling amp large rear-end vents for increased ventilation.

S-Works Evade 3 front-end design language for enhanced Aerodynamics. Precision, full-wrap polycarbonate shell for increased durability and premium finish.
