When time is of the essence, no other helmet will get you from start to finish faster than the S-Works TT. In order to create the fastest TT helmet out there, we turned to the design of the S-Works McLaren TT to make a helmet that truly differentiates itself from the 'competition.' The biggest innovation found on the S-Works TT is the patented Gill Vents that pull air into the helmet and allow it to freely flow out of the rear exhaust port. This makes for a time trial helmet that's not only fast (62 seconds over 40 kilometers compared to a standard road helmet to be exact), but will also keep you cool on the course. A fast helmet is useless if it doesn’t fit well, after all, so that’s why we spec'd the S-Works TT with our height-adjustable Mindset micro-dial fit system that makes for a tremendous fit and fast transitions. This, along with our lightweight 4X DryLite webbing that won’t stretch out with sweat or water and Instrap webbing system for ultra-light construction and security, make for a TT helmet that provides comfort over the long haul. Each S-Works TT helmet has been designed around a removable shield, which means that you get a TT helmet that's just as fast with a shield as it is with sunglasses—the first of its kind. Each helmet comes with two removable shields (Smoke and Clear) that allow for the ultimate in visibility when cranking out power while in the aerobars. With our most advanced Win-Tunnel-developed aerodynamics and ventilation, the S-Works TT helmet is your best option for pure speed. - Advanced wind tunnel developed aerodynamics and ventilation saves 62 seconds over 25 miles/40km (over a standard road helmet) - Innovative Gill Vent design improves airflow and reduces drag - Removable Shield has a robust snap fit and comes with both clear and smoke tints - Ultra-light, Mindset micro-dial fit system with height adjustability for a perfect fit - Tri-Fix strap splitter for improved comfort and ease of strap adjustments - Thin, soft and lightweight 4X DryLite padding won’t stretch out with sweat or water - Instrap webbing system for ultra-light construction and security - Complies with one or more of the following safety standards for bicycle helmets: CPSC, SNELL B90A, CE and AS/NZS

Helmets have long been plagued by an unspoken rule: Low weight, ventilation, aerodynamics-pick two, there's your helmet. As you can tell by now, though, we don't play by these rules—or really any for that matter. We'd rather turn standards on their head and create products that nobody ever dreamed of. And you needn't look any further than the new S-Works Evade helmet for proof of this. Straight up, it's the fastest road helmet out there. - Through extensive Win Tunnel development, the Evade is the fastest road helmet we've tested. - 4th Dimension Cooling System with deep internal channels, large vents, and aligned exhaust ports make it the best combination of aerodynamics and ventilation. - Patented Energy Optimized Multi-Density EPS construction helps to manage impact energy. - Patented Aramid-Reinforced Skeleton provides internal EPS support to help manage impact energy. - Ultra-light Mindset HairPort II micro-dial fit system with height adjustability for the perfect fit. - Gutter Action brow pad design for increased comfort and sweat management. - Thin, soft, and lightweight 4X DryLite webbing won't stretch out with sweat or water. - Tri-Fix web splitter for improved comfort and ease of strap adjustments. - Instrap webbing system for ultra-light construction and security. - MIPS-equipped. - Integrated ANGI crash sensor. - Magnetic buckle is simple and secure.

Helmets have long been plagued by an unspoken rule: Low weight, ventilation, aerodynamics—pick two, there's your helmet. As you can tell by now, though, we don't play by these rules—or really any for that matter. We'd rather turn standards on their head and create products that nobody ever dreamed of. And you needn't look any further than the new S-Works Evade helmet for proof of this. Straight up, it's the fastest road helmet out there. Beginning with the aerodynamic development, we basically lived in our Wind Tunnel to create this Evade. Having our own wind tunnel allows us to develop our products with aero at the forefront of the design, rather than merely testing them there. With this, we carefully analyzed every aspect of helmet performance in the Win Tunnel, and with real-world testing, to ensure that we left no stone unturned in the quest for performance. This makes for a helmet that has countless testing hours and years of development, and ultimately, this adds up to the fastest road helmet we've ever tested. We not only took grams out of the drag, but we did it without sacrificing safety. In fact, we switched the construction to favor our Energy Optimized Multi-Density EPS that optimizes the foam type in different places. As far as ventilation is concerned, free-flowing air through the helmet not only makes the helmet cooler than ever, but it also decreases aerodynamic drag. Going hand-in-hand with this, ventilation and aerodynamics were both optimized in the Win Tunnel together, making for the best combination of aerodynamics and ventilation out there. Now, the exterior vents and interior channels have been carefully considered to make sure that the helmet draws in the maximum amount of air through the helmet for extreme cooling. And the result? The new Evade is just as cool as a bare head with no helmet, making it the coolest aero helmet on the market today. Through this work, the Evade saves 50 seconds over 40km versus a traditional road helmet and roughly six seconds over the prior iteration of Evade. This means that it's not only as cool as a bare head, but also as fast. For road race helmets, there's nothing that can match this performance. Last, but most certainly not least, a fast helmet is useless unless it fits correctly. With this in mind, the new S-Works Evade has all the features you'd expect from a top-level helmet, like our Mindset HairPort 2 fit system with micro-adjustments, our soft webbing that won't stretch out, and a new Gutter Action brow pad that manages sweat to keep it out of your eyes. And to top it off, we've added a new magnetic buckle to the mix that makes buckling with one hand a breeze. - Through extensive Win Tunnel development, the Evade is the fastest road helmet Specialized has ever tested. - 4th Dimension Cooling System with deep internal channels, large vents, and aligned exhaust ports make it the best combination of aerodynamics and ventilation. - Patented Energy Optimized Multi-Density EPS construction helps to manage impact energy. - Patented Aramid-Reinforced Skeleton provides internal EPS support to help manage impact energy. - Ultra-light Mindset HairPort II micro-dial fit system with height adjustability for the perfect fit. - Gutter Action brow pad design for increased comfort and sweat management. - Thin, soft, and lightweight 4X DryLite webbing won't stretch out with sweat or water. - Tri-Fix web splitter for improved comfort and ease of strap adjustments. - Instrap webbing system for ultra-light construction and security. - Magnetic buckle is simple and secure.

It even boasts revolutionary dual-density EPS foam for protection without bulk. And, Specialized's Mindset retention system and Tri-Fix straps let you dial in the perfect fit.

When we set out to improve the original S-Works Prevail, we knew that we had our work cut out for us. How could we improve on the industry benchmark for fit, ventilation, and comfort? By listening to our riders—that’s how. Through this, we realized that there were a few aspects of the original Prevail II that needed to be changed, with the biggest request being for a lower-sitting design. We thought to ourselves, "thinking big shouldn't result in bigger helmets," so with the Prevail, we set out to prove that big ideas can come in smaller packages. It all starts with our patented EPS construction that relies on multi-density foam that's paired with a robotically woven, Aramid-reinforced skeleton. This comes with a reduction in the overall size, creating a smaller profile that fits lower down on the head for a better fit and safety. It also has deep internal channels that are aligned from front-to-rear, so the air intake and exhaust are optimized for unparalleled cooling over the entire head. And in the Win Tunnel, we found these new designs amounted to six seconds saved over 40km when compared to a "standard" road helmet. Another standout feature of the S-Works Prevail II is the Gutter Action System that manages the flow of sweat, keeping it away from your eyes and dripping it off of the pads over your temple. Our new ANGi Crash Sensor gives you and your loved ones peace of mind like never before—when combined with our iOS or Android app, the sensor will detect a crash and send a text message to specified contacts in your phone. It also syncs with our app and STRAVA to provide GPS-based activity tracking.

The Specialized S-Works Evade shares its roots with some illustrious company, namely, the fastest TT helmet in the world, the S-Works McLaren TT. When they set out to design it, Specialzied wanted to create a helmet that had all the aerodynamic benefits of a TT helmet, only without sacrificing fit or ventilation. The logical place to start was with the shape. If you place the Evade and S-Works TT helmet side by side, you’ll notice they bear a striking resemblance to one another. The Evade uses the same profile shape as the TT, which results in a drastic decrease in drag. How drastic? Compared to the S-Works Prevail, it saves you 46 seconds over 40km. Making an aerodynamic road helmet is one thing, but ensuring that the fit and comfort are up to par is something else entirely. After all, one of the main detractions with TT helmets is that they don’t vent particularly well. And when you’re spending five hours in the saddle, you need to be sure that you’re getting proper venting to keep you cool. The Evade checks all these boxes, though. And with strategically positioned air vents, the S-Works Evade actually draws air around your head and then channels it out the rear exhaust ports to make sure that you keep cool when temperatures rise around you. But what good is a helmet if it isn't comfortable? No matter how fast it is, we all know that a helmet will collect dust if it's uncomfortable. The Trifix web splitter fit system, combined with a five-step height adjustment and ultra-light Mindset micro-dial, ensures comfort by making the perfect fit intuitive, easily obtainable, and completely foolproof. - Advanced aerodynamics saves 46 seconds over 40km compared to standard road helmet. - Patented Aramid-Reinforced Skeleton provides internal EPS support to help manage impact energy. - Ultra-light Mindset micro-dial fit system with height adjustability for the perfect fit. - 4th Dimension Cooling System with deep internal channels, large vents, and aligned exhaust ports. - Thin, soft, and lightweight 4X DryLite webbing won’t stretch out with sweat or water. - Tri-Fix web splitter for improved comfort and ease of strap adjustments. - Instrap webbing system for ultra-light construction and security.
