At Escapa, we know that the protection a good helmet offers is very important, which is why we’re introducing the Specialized Propero 4 Helmet.
The new Propero 4 helmet stands out for its aerodynamics, ventilation, and lightweight design. It combines the aerodynamic benefits of the S-Works Evade 3 with the ventilation of the S-Works Prevail 3, all with the comfort and confidence you expect from Specialized.
AERODYNAMICS
After extensive CFD and wind tunnel testing, aerodynamics were at the forefront of the Propero 4’s development. We took the aerodynamic leading edge from the S-Works Evade 3 and incorporated it directly into the Propero 4, which helped make it four watts—or 15 seconds over 40 km—faster than our S-Works Prevail 3.
VENTILATION
Drawing inspiration from our world-famous S-Works Prevail 3, our goal wasn’t simply to replicate it but to elevate it. Ventilation became a central focus in our quest for a well-balanced, aerodynamic, and ventilated helmet. We incorporated the rear design language of the S-Works Prevail 3 and introduced small, 2-mm-offset microchannels that create turbulence in the airflow throughout the helmet to help generate a continuous, cooling airflow.
BETTER
Beyond aerodynamics and ventilation, the Propero 4 represents meticulous attention to detail. We went the extra mile by incorporating cutting-edge technologies into our S-Works-level helmets, such as Mips technology to provide peace of mind and a fit system designed for all-day comfort. The Propero 4 doesn’t just meet expectations—it redefines them.
FEATURES
- Mips Evolve Solution is a low-friction layer that allows for 10 to 15 mm of sliding movement in all directions. Studies indicate that this reduces some of the rotational forces transmitted to the brain during angled impacts.
- The Propero 4 earned the highest 5-star Virginia Tech® helmet rating from the internationally recognized Virginia Polytechnic Institute and State University.
- The FS3 fit system and occipital base adjustment optimize comfort by customizing the fit to the individual head shape, and the helmet’s angle can be adjusted to accommodate glasses.
- Adjustable Tri-Fix mesh divider combined with 10-mm-wide straps for added comfort.
- Exclusive sunglasses storage keeps them securely in place and out of the way when needed.
- Micro-channels and large rear vents provide enhanced ventilation.
- S-Works Evade 3 front design language for improved aerodynamics.
- Precision-molded, full-wrap polycarbonate shell for durability and a premium finish.
