Specialized Propero 4 Helmet

The Propero 4 helmet combines aerodynamic elements from the S-Works Evade 3 with the ventilation features of the S-Works Prevail 3. It offers a four watt advantage over the Prevail 3 while maintaining high airflow through Micro Channeling technology. This system creates continuous internal air movement to manage heat effectively during intense cycling efforts in various conditions.

Safety remains a priority with a 5-Star Virginia Tech rating and the Mips Evolve Solution to manage rotational forces. The FS3 Fit System includes an Occipital Base Adjustment to allow for personalized positioning and secure sunglass storage. These features ensure a stable fit that works with eyewear while providing professional level performance and protection on every road ride.
