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.

LIGHTER, COOLER, SLEEKER, PLUS ALL THE ADDED PROTECTION OF SPHERICAL TECHNOLOGY POWERED BY MIPS® AND OUR NEW DRYCORE™ SWEAT MANAGEMENT SYSTEM: THE ARIES SPHERICAL IS LIKE NOTHING BEFORE. STRUCTURAL INTEGRITY The proprietary AURA II Reinforcement Arch makes everything possible. These shatter-resistant, translucent twin bridges run throughout the helmet, providing structural integrity without adding unnecessary weight. Aries’ ultra-low weight (~5% lighter than Aether), impressive cooling power and sleek, compact shape would not be possible without AURA II. SPHERICAL TECHNOLOGY This unique ball-and-socket design, powered by Mips®, helps redirect impact forces. Spherical Technology also boasts more comfort, improved airflow, and Progressive Layering (which mates two densities of EPS foam to address a wide range of impact energy). The results are clear: independent authority Virginia Tech has rated Aries #1 in reducing the risk of injury. It’s the best performing helmet they’ve tested so far – even out-performing much bigger, bulkier helmets at reducing risk. COOL COMFORT Deep internal channels connect with Aries’ massive front and rear vents. This system provides a path for cool air to flow over the rider’s scalp and exit the rear, taking excess heat with it. Aries outperforms our previous cooling benchmark, the Aether, with a 2.3% improvement in cooling efficiency. STREAMLINED SPEED When it comes to going fast, smaller truly is better. To craft Aries, we focused on reducing the frontal surface area to eliminate more drag. Add in tiny details like chamfered edges on the AURA II, and meticulously engineered internal channeling that actually speeds up the air as it exits the helmet, and Aries emerges as the climbing helmet that doesn’t sacrifice speed, reducing aerodynamic drag by 4% over Aether Spherical. Aries also debuts our revolutionary DryCore™ sweat management system. A soft, silicone bead is hidden within the plush brow pad that redirects sweat away from the forehead and to the temples, where it can evaporate more easily. LIKE NOTHING A helmet that feels like it isn't there: the all-new Aries™ Spherical is like nothing before. Its sleeker form and lighter weight (only 270 grams in size medium, CE certification), deliver sensational comfort and cooling power. Spherical Technology™, our ball-and-socket design powered by Mips®, adds protection by redirecting energy away from the brain in certain impacts, and Progressive Layering with dual densities of Nanobead EPS foam adds more comprehensive energy management. 24 Wind Tunnel vents are maximized by the AURA II Reinforcement Arch, while a plush DryCore™ brow pad manages sweat and combines with a network of intricately engineered deep internal channeling to elevate comfort. From the proven reliability and adjustability of the Roc Loc® 5+ Air fit system, to full lower hardbody coverage to enhance durability, to the meticulous production quality, the Aries is state-of-the-art performance, protection, and style.

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.

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.
