Meet the all-new Propero 4 helmet—it 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 our equation for speed in mind. Aerodynamics +
Ventilation + Lightweight = Fast.AERODYNAMICS: 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.
VENTILATION: 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.ATTENTION 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 doesnt just
meet expectations; it redefines them.
