Specialized Propero 4 Helmet<\/h2>\n

The Propero 4 combines the aerodynamic advantages of the S-Works Evade 3 with the superb ventilation of the S-Works Prevail 3, without compromising comfort or, most importantly, safety. With the Propero 4, we've designed a high-performance racing helmet that excels in every category, from aerodynamics and ventilation to weight. From newcomers to seasoned veterans, the Propero 4 is a helmet for all racers, ready to help shave off those crucial seconds.<\/p>\n<\/div>\n

\n

AERODYNAMICS: Aerodynamics were paramount in the development of the Propero 4. We conducted extensive studies in computational fluid dynamics and tests in our WinTunnel until we achieved the perfect design. It's no surprise, then, that the new Propero bears a strong resemblance to the S-Works Evade 3 from the front. It was a lot of effort, but it paid off in the end, as the Propero 4 is a full 15 seconds faster over 40 km than our S-Works Prevail 3. That equates to four watts of power that can now be converted into speed.<\/p>\n

VENTILATION: Just as important as aerodynamics is the ventilation of the Propero 4. Here, too, we drew inspiration from our S-Works helmets. We didn't simply want to copy the S-Works Prevail 3, however. We wanted to integrate and improve its ventilation system into the new design. Ultimately, we opted for its rear vents and added a new system to the Propero 4. Micro Channeling consists of tiny air channels, only 2 mm in diameter, that swirl the airflow throughout the helmet, ensuring continuous ventilation and refreshing coolness.<\/p>\n

ATTENTION TO DETAIL: Of course, we didn't limit ourselves to aerodynamic properties and ventilation during development. We considered every single detail and incorporated as much technology as possible from our S-Works helmets \u2013 including MIPS\u00ae technology for added confidence and an adjustment system that provides all-day comfort. The new Propero 4 therefore perfectly meets our requirements for a high-end performance helmet for competition.<\/p>\n<\/div>\n

Highlights<\/h3>\n
    \n
  • The MIPS Evolve system consists of a low-friction layer that allows for a gliding movement of 10 to 15 mm in all directions. Studies indicate that this layer effectively reduces the rotational forces transmitted to the brain during lateral impacts.<\/li>\n
  • The Propero 4 has received 5 out of 5 stars in the Virginia Tech\u00ae Helmet Rating\u2122 from the internationally renowned Virginia Polytechnic Institute and State University.<\/li>\n
  • The FS3 adjustment system and the ability to adapt to individual skull bases optimize comfort. Additionally, the helmet angle can be adjusted for better compatibility with different goggles.<\/li>\n
  • The adjustable Tri-Fix strap system ensures a secure hold, and the straps, which are only 10 mm wide, increase comfort.<\/li>\n
  • Special channels in the helmet safely transport your sunglasses when you don't need them.<\/li>\n
  • Large rear vents, like those on the S-Works Prevail 3, and micro channeling improve ventilation.<\/li>\n
  • The design language of the S-Works Evade 3 stands for first-class aerodynamic properties.<\/li>\n
  • Surrounding shell made of precisely machined polycarbonate for increased durability and high-quality surfaces.<\/li>\n<\/ul>\n<\/div>\n
