Specialized Propero 4 MIPS Helmet

Specialized Propero 4 MIPS road cycling helmet in Sandstone Metallic. Specialized product code: 60126-1704

Introducing 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 famous for, earning the highest 5-star rating from Virginia Tech®. Every detail of the Propero 4 was designed with our speed equation in mind. Aerodynamics + Ventilation + Lightweight = Speed.

AERODYNAMICS: With extensive CFD testing and testing in our Wind Tunnel, aerodynamics was at the forefront of the Propero 4's development. We took the aerodynamic design of the helmet to the next level to create 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 our 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, helping to create a continuous and refreshing airflow. Ventilation became the focal point of our quest for a well-balanced, aerodynamic, and highly ventilated helmet.
