Aero & Aero Road Helmets

Giro's Aerohead MIPS takes the same wind-cheating silhouette as the leading-edge Aerohead Ultimate, but adds increased ventilation to keep triathletes and time trialists cool when the competition is hot. By using a polycarbonate shell, Wind Tunnel ventilation, and internal channeling, this helmet is proven to boost cooling power while remaining aerodynamic. Additionally, Aerohead MIPS features a wrap-around eye shield that offers an impressive field of view with the convenience of a magnetic anchor attachment to allow easy storage of the lens in the "flipped up" position—perfect for fast swim-to-bike transitions.

Meet the all-new Propero 4 helmet—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, earning the highest 5-Star Virginia Tech® helmet rating. Every detail of the Propero 4 was created with our equation for speed in mind. Aerodynamics + Ventilation + Lightweight = Fast. AERODYNAMICS: With extensive testing in CFD and in our Win Tunnel, aerodynamics were at the forefront of the Propero 4 development. We took the aerodynamic leading edge from the S-Works Evade 3 and pulled it directly into the Propero 4—which helped it to be four watts, or 15 seconds over 40km, faster than our S-Works Prevail 3. VENTILATION: Drawing inspiration from our world-renowned S-Works Prevail 3, our goal was not merely to replicate but to elevate. Ventilation became a focal point in our quest for a well-balanced, aerodynamic, and ventilated helmet. We incorporated the rear-end design language of the S-Works Prevail 3 and introduced small 2mm offset micro-channels that create turbulence in the airflow throughout the helmet to help create a continuous, refreshing flow of air. ATTENTION TO DETAIL: Beyond just aerodynamics and ventilation, the Propero 4 represents meticulous attention to detail. We went the extra mile by incorporating cutting-edge technologies from our S-Works level helmets, like MIPS technology for confidence, and a fit system designed to deliver all-day comfort. The Propero 4 doesn't just meet expectations - Mips Evolve Solution is a low-friction layer that allows a sliding motion of 10 to 15mm in all directions. Studies indicate that this reduces some of the rotational forces transmitted to the brain during angled impacts. - Propero 4 earned the highest 5-Star Virginia Tech® Helmet Rating from internationally renowned Virginia Polytechnic Institute and State University. - FS3 Fit System & Occipital Base Adjustment optimizes comfort by personalizing fit to individual head shape, and helmet angle can be adjusted for compatibility with glasses. - Adjustable Tri-Fix web splitter combined with thin 10mm webbing for increased comfort. - Dedicated sunglass storage maintains a secure fit and keeps eyewear out of the way when needed. - Micro Channeling & large rear-end vents for increased ventilation. - S-Works Evade 3 front-end design language for enhanced Aerodynamics. - Precision, full-wrap polycarbonate shell for increased durability and premium finish

The most aero road helmet in the peloton now breathes better. The S-Works Evade 3 was reinvented from the inside out to cool better, making it the fastest choice for more stages. Through extensive Computational Fluid Dynamics and Win Tunnel testing, we created a rear "diffuser" that helps minimize drag and improve ventilation. The diffuser helps optimize aero performance by allowing air to release easier and improves ventilation by drawing 10% more air through the helmet at a given speed. The Occipital Base Adjustment optimizes comfort by personalizing fit to individual head shape and helmet angle can be adjusted for compatibility with glasses. An adjustable Tri-Fix web system gives riders added comfort with updated, thinner 10mm webbing that minimizes strap noise. And the ANGi-ready, ultralight Mindset micro-dial fit system with height adjustability has been updated for improved grip and reaction for easy on-the-go fit. Our ultralight and supremely comfortable MIPS Node Air technology is integrated directly into the helmet padding, with a sleek low friction layer designed to dissipate rotational forces. With Specialized's proprietary development work, we added perforations to maximize breathability, performance, comfort, and weight savings. - Enlarged front vents help increase ventilation. - Rear Diffuser for aero and ventilation benefits. - MIPS Air Node is MIPS' most ventilation-focused solution. - Adjustable Tri-Fix web splitter boosts comfort through personalized fit. - Precision, full-wrap polycarbonate shell for increased durability and premium finish. - Dual-density optimized EPS foam.
