Specialized Propero 4 MIPS Helmet

Specialized Propero 4 road cycling helmet in Sandstone Metallic color. Specialized reference: 60126-1704

Meet the new Propero 4 helmet—it brings the aerodynamic advantages of the S-Works Evade 3 along with the ventilation of the S-Works Prevail 3, all with the comfort and confidence that Specialized helmets are known for, earning the highest 5-star rating from Virginia Tech®. Every detail of the Propero 4 was created with our speed equation in mind. Aerodynamics + Ventilation + Lightweight = Speed.

AERODYNAMICS: With extensive CFD and wind tunnel testing, aerodynamics was at the forefront of the Propero 4's development. We took the aerodynamic advantages of the helmet and created a faster helmet. We took the aerodynamic front of the S-Works Evade 3 and molded it directly into the Propero 4, which contributed to it being four watts, or 15 seconds faster over 40 km, than our S-Works Prevail 3.

VENTILATION: Inspired by our world-renowned S-Works Prevail 3, our goal wasn't simply to replicate it, but to take it further. Ventilation became a central focus in the quest for a well-balanced, aerodynamic, and ventilated helmet.

We incorporated the rear design of the Prevail 3 and introduced small, 2mm offset microchannels that create turbulence in the airflow across the entire helmet to help create a continuous, cooling airflow. Ventilation became the focal point of our quest for a well-balanced, aerodynamic, and ventilated helmet.
