On the last day before time trials at the Tour de France, teams are on their last seconds to fine-tune their kits. Specialized team riders will choose from a quiver of three updated S-Works helmets.
The new lineup of Specialized S-Works helmets encompasses three familiar models, all optimized for airflow and aerodynamics. Each one focuses on a specific set of conditions and riding disciplines.
To perform the upgrades, Specialized rolled out fluid dynamics, finite element analysis, and testing on multiple continents including aero trials in its “Win Tunnel.” Rider feedback informed the process that ultimately produced the competition-focused Evade 3, lightweight Prevail 3, and speed-optimized TT5.
Without further ado, here are the three models you’ll see on the noggins of Specialized riders.
S-Works Evade 3
When Specialized looked at updates the Evade 2 needed, it found the most room for growth in airflow. But fluid dynamics tests also showed its slight teardrop shape made sense. Making aero gains would require a redesign that didn’t compromise overall form factor.
Enlarged front vents primarily help increase airflow. A rear diffuser, brand new to the design, helps airflow as well but also supports aerodynamics at the top back of the helmet. That area, according to Bikerumor, was one of the previous design’s few draggy spots.
