Adult Bicycle Helmets

The S-Works Prevail 3 helmet is perfect for riders who value the comfort and thermoregulation benefits that superior ventilation delivers. It is the ultimate all-around helmet that excels in hot conditions, strenuous climbs, and mountainous stages. With a never-ending quest to push the limits of ventilation, we eliminated air-blocking foam "bridges" from the center, effectively creating thru-air channels that increase the surface area of ventilation by 24.5% compared to the S-Works Prevail II Vent helmet. The all-new S-Works Prevail 3 has the most ventilation area of any helmet we have ever made. When a helmet is impacted, its job is to dissipate the energy of the impact. The conventional approach to helmet design is that more foam (EPS) means better energy management. We re-wrote the book on cycling helmet design by innovating beyond foam. Woven aramid "cables" traverse the helmet and are anchored to carbon fiber side panels. Upon impact, the AirCage technology* works as a suspension bridge and is designed to distribute localized forces throughout the helmet. 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. - AirCage innovation increases airflow. - Precision, full-wrap polycarbonate shell for increased durability and premium finish. - MIPS Air Node technology is MIPS' most ventilation-focused solution. - Adjustable Tri-Fix web splitter boosts comfort through personalized fit. - Occipital Base Adjustment optimizes comfort and compatibility with glasses. - ANGi-ready Mindset fit system for improved grip and reaction for easy on-the-go fit.

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.

For Dissident II, we collaborated with powerhouse athletes, Loïc Bruni and Finn Iles, to design a helmet that would meet the highest demands of downhill mountain bike racing, in terms of confidence, a modern-styled fit, and breathability.With five strategically placed EPS foam inserts, we’re able to tune for higher and lower density foam based on where it is being configured inside the helmet—allowing us to maintain a light weight and still manage energy. The use of a softer foam density allows more energy to be absorbed in an impact, transferring less to the rider. Dissident II also provides added confidence through its Mips Evolve Solution—that helps to redirect rotational movement away from the head. In this Evolve Solution, we utilized fabric pocket attachments inside, reducing creakiness.Remaining cool is more than a state of mind, and it’s hard to keep your composure when things get hot—specially when your head feels like its in a sauna. That’s why instead of focusing on more vents, we focused on better vents. Built from the inside out, the Dissident II ventilation system features a hood scoop to channel a flow of cool air in, and purpose-placed vents that direct the warm air out—letting your head stay cool and comfortable in any situation.Keeping this helmet light was of high importance. In a race context, feeling light and mobile leads to faster reactions, and reduced fatigue between the tape. With the EPS foam insert construction, the helmet remains very light while still offering big protection. While we can’t speculate on everything that was going through Finn Iles’ head during his 2022 winning run at Mont-Sainte-Anne—we know what he wasn’t thinking about… Whether you’re taking the stage to drop in on your first winning World Cup run, or chasing your own championship on the local enduro series, Dissident II has you covered.For helmets sold in the U.S. and Canada: Complies with U.S. CPSC Safety Standard for Bicycle Helmets for Persons Age 5 and Older. - 3 Layer Construction: Carbon Shell / Poly Carbonate / EPS. - 5-unique pieces of EPS tuned to optimized performance in each specific location. - Mips Evolve Solution: Fabric pocket attachments to reduce bobble head and creakiness. - Ionic Plus Fabric anti-microbial pad kit.
