Road Racing · Aero · Ventilation · MIPS Evolve

Meet the all-new Propero 4—it brings the aero advantages of the S-Works Evade 3 together with the ventilation of S-Works Prevail 3, all with the comfort and confidence Specialized helmets are famous for. Every detail was created with our equation for speed in mind: Aerodynamics + Ventilation + Lightweight = Fast.

  • 4 Watts Faster: Four watts faster than S-Works Prevail 3—15 seconds over 40km, proven in Win Tunnel testing.
  • MIPS Evolve Solution: Low-friction layer reduces rotational forces during angled impacts.
  • FS3 Fit System: Occipital base adjustment personalizes fit and tunes helmet angle for glasses compatibility.
  • Evade 3 Aero DNA: S-Works Evade 3 front-end design language for enhanced aerodynamics.
  • Prevail 3 Ventilation: Rear-end design with micro-channeling creates continuous airflow.
  • Dedicated Sunglass Storage: Secure eyewear storage when you need them out of the way.
  • Tri-Fix + 10mm Webbing: Adjustable splitter with thin webbing for all-day comfort.

Aerodynamics + Ventilation + Lightweight = Fast. Simple math, dominant results.

4 Watts Faster
Extensive testing in CFD and our Win Tunnel proved it—Propero 4 is four watts faster than S-Works Prevail 3. That's 15 seconds over 40km. S-Works Evade 3 aerodynamic leading edge pulled directly into Propero 4.
MIPS Evolve Solution
Low-friction layer allows a sliding motion of 10 to 15mm in all directions. Studies indicate this reduces rotational forces transmitted to the brain during angled impacts—confidence to go fast.
Prevail 3 Ventilation DNA
Drawing inspiration from S-Works Prevail 3, small 2mm offset micro-channels create turbulence throughout the helmet to generate continuous, refreshing airflow. Not just replicate—elevate.
FS3 Fit System + Occipital Base Adjustment
Personalizes fit to individual head shape. Helmet angle can be adjusted for compatibility with glasses—perfectly synched every ride.
Dedicated Sunglass Storage
Maintains a secure fit and keeps eyewear out of the way when needed. Rattle-free, secure, always accessible.
