CASCO SPECIALIZED PROPERO 4 MIPS
Here is the new Propero 4 helmet – the aerodynamics of the S-Works Evade 3 combined with the exceptional ventilation of the S-Works Prevail 3, and furthermore the comfort and reliability of all Specialized helmets, plus the 5-star rating from Virginia Tech Institute®. Every detail of the Propero 4 has been designed with the equation Aerodynamics + Ventilation + Lightweight = Speed in mind.
AERODYNAMICS: In developing the Propero 4, aerodynamics was the starting point, and for this we conducted numerous CFD tests and wind-tunnel sessions. With the profile inspired by the S-Works Evade 3, we gain already 4 watts, i.e., 15 seconds over a 40 km distance.
VENTILATION: Drawing from the S-Works Prevail 3 helmet, we achieved our quality objectives. We incorporated the rear exhausts of the S-Works Prevail 3 and introduced 2 mm micro-channels that create turbulence in the airflow through the helmet, thereby creating a continuous and refreshing air passage.
ATTENTION TO DETAIL: Beyond aerodynamics and ventilation, the Propero 4 is characterized by meticulous attention to detail. We have applied cutting-edge technologies such as MIPS and a fit system designed for comfort. The Propero 4 exceeds expectations.
CASCO SPECIALIZED PROPERO 4 MIPS KEY FEATURES:
- MIPS C-Solution technology
- On the Virginia Tech® Helmet Rating™ scale from Virginia Polytechnic Institute and State University, the Propero 4 earned 5 stars, the best rating.
- The FS3 retention system and the occipital base adjustment allow fine-tuning to the individual head shape. The helmet’s position angle can be adjusted for compatibility with glasses.
- TriFix strap system for optimal comfort.
- Glasses insertion capability.
- Thin straps, 10 mm wide.
- Large rear exhausts and internal micro-channels for maximum ventilation.
- Precision, full-wrap polycarbonate shell for increased durability and premium finish.
- Very durable polycarbonate shell with a first-class quality finish.
