Specialized S-Works Evade 4 Cycle Helmet Traditionally, choosing an aero helmet meant sacrificing ventilation, but Specialized has shattered that compromise. Thanks to an advanced 4D Cooling System, the S-Works Evade 4 Cycle Helmet is an impressive 2.4% cooler than its predecessor, the Evade 3. This means you can sustain your peak output for longer, staying fresh and focused when defending a breakaway or pushing through the final kilometres of a gruelling gravel race. Advanced Aerodynamics The Evade 4 leads the pack in speed. Even with the added ventilation, Evade 4 is Specialized's fastest everyday race helmet. It begins with TT5-inspired shaping that reduces overall drag while rear diffuser channels release air cleanly and efficiently. Meanwhile, long, narrow side vents ensure aero performance and ventilation work in perfect harmony. Sophisticated Fit Beyond its aerodynamic prowess, the Evade 4 introduces a highly sophisticated fit system designed for all-day comfort and top-tier safety. It features a new headform, the BOA® FS2 Fit System, and Tri?Fix 5 splitters, offering a 360-degree micro-adjustable fit with 40% finer adjustment points via a tactile dial. These all combine to give a fit-and-forget feel - comfort is performance.  Mips® Air Node Pro For peace of mind, the helmet incorporates Mips® Air Node Pro technology directly into the padding for superior rotational impact protection, earning it a prestigious Virginia Tech 5-Star safety rating. Complete with removable pads in two thicknesses for custom sweat management, the Evade 4 isn't just a piece of kit-;it’s a genuine performance investment that ensures you ride faster, cooler, and safer.
