Faster and Cooler Than Ever
The new S-Works Evade 4 represents the new pinnacle of Specialized's fastest race helmets. Designed in Specialized's own WinTunnel, tested in WorldTour racing, and verified through over 100 hours of aerodynamic and thermal analysis, the Evade 4 achieves a balance that few helmets manage: world-class aerodynamics, cooling performance, and enhanced comfort.
In addition to re-engineered ventilation, the new MouthPort (forehead air intake) has been reintroduced, and internal air channels have been optimized. Furthermore, the head form was updated to improve fit, comfort, and airflow. As a result, the Evade 4 achieves a 2.4% improvement in cooling performance without sacrificing any aerodynamic efficiency.
This is a helmet for riders pursuing peak performance—whether for podiums, personal bests, or high-paced group rides. It is not just about speed; it is about going faster, for longer. Cooling and comfort are what sustain speed.
Aerodynamics to Win
The aero story of the Evade 4 begins in Specialized's WinTunnel. By improving vent shapes and helmet surface airflow, aerodynamic performance is enhanced without disrupting airflow.
Optimized vent structure and NACA vents reduce air resistance while boosting cooling performance.
Thin, long side vents maintain smooth airflow. Inspired by the TT5, the flat top and tail fin silhouette reduce turbulence.
2.4% Cooler
The Evade 4 offers a 2.4% improvement in cooling performance over the previous Evade 3, verified by independent testing using thermal analysis head forms. This test will be standard for all future helmet developments.
Coolness brings victory. A cool head enhances power and performance.
The re-engineered MouthPort increases intake airflow. 4D cooling internal channels guide air deep into the helmet, and the rear diffuser directs it to the back.
The new Mips® Air Node Pro pad design controls sweat flow.
Fit, Comfort, and Confidence
The Round Fit, developed with Asian market riders, improves fit through all-directional shape adjustment and a revised internal profile, providing a deeper, more stable fit than before. While the size chart remains the same, it achieves a more natural and secure fit.
