Aero helmets often compromise cooling for aerodynamic gains but with their Ventral Air SPIN Helmet, POC has managed to combine slippery streamlining and impressive cooling, making this a helmet for fast and hot days on the bike. Using CDF analysis the Ventral has been designed to create minimal air turbulence while precisely placed intake and exhaust vents suck air through internal channels, turbocharging the cooling performance of the helmet. Whether it's a high-speed ride on the flat or toiling up a hot climb this precision venting works to keep you cooler and sweat-free. The updated POC Ventral Air MIPS helmet is now available POC Protection You can also be confident head protection isn't compromised in pursuit of venting and aerodynamic performance. The EPS liner features multi-density zones to deliver targetted crash protection and this also helps keep weight low, just 230 grams for a size medium. The unibody shell is full-wrapped enhancing safety and helmet integrity while the straps are anchored to the helmet for a greater degree of hold in the event of a crash. Lastly, a lightweight size adjustment system keeps the helmet locked in place, vital should you take a fall. SPIN (Shearing Pad INside) Unlike most of its rivals who deploy the popular MIPS technology, POC has created their very own protective system known as SPIN, a patent-pending rotational impact protection system that reduces the effects of an oblique fall by limiting the amount of force transmitted to the head and brain. Using an innovative and unique pad technology to keep you safe you'll be protected from unexpected falls and install a new level of confidence as you ride. As used by the EF Education First Pro Cycling Team, the Ventral Air SPIN Helmet delivers coolness and aerodynamics in equal measure, letting you push harder than ever in pursuit of your cycling goals.
Our new performance helmet is designed to deliver coolness in ways like never before. With precise ventilation ports and internal channels to control air intake and release at both low and high speeds, the helmet provides a supreme cooling effect over the whole head. Ideal for long rides in the mountains or hotter days in the saddle. Winner of the coveted Design and Innovation Award 2019, the Ventral Air SPIN works to enhance a riders aerodynamic profile and minimize drag. Specific airflow zones enhance ventilation and cooling, while the aerodynamically optimized trailing edge reduces turbulence. The exceptionally lightweight Ventral Air SPIN has been developed according to our wholehelmet approach. It features a fully wrapped unibody shell construction and an EPS liner, delivering an ideal balance between weight and safety. Our patentpending silicone pad technology system SPIN also features. Practical features include a lightweight size adjustment system that guarantees a personalized fit, and an eye garage for easy and secure storage of eyewear when not in use.
POC Ventral SPIN HelmetIntroducing the finest aerodynamic performance the road has ever seen! The POC Ventral Spin Helmet welcomes the expert opinion of professional riders and has been thoroughly tested in the WATTS Lab to ensure speed, safety and high-end ventilation.Digging deep into their extensive knowledge and working with the Cannondale – drapac Pro Cycling Team to create what will certainly set the benchmark for road helmets, POC have gone all out with the Ventral Spin. Sporting a unique design to shred time off your personal best, this stylish lid leads air through the head rather than around it to reduce wake and boost your aerodynamic performance. There is the inclusion of airflow zones to create a range of different pressure points, increasing airflow and speed which delivers air around the head more efficiently. Known as the Venturi effect, your next ride is certain to be one of the coolest ones yet.With their high-end ventilation improving performance and comfort, it is fair to say the Ventral Spin Helmet really is one of the finest forms of protection on the market. Keeping you free from sweat and the build-up of odours, it also allows for residual air to travel over and around the lid. This is an impressive ability that is controlled by the aerodynamically optimised trailing edge to help limit turbulence, generating a longer linear airflow off both rider and helmet. Helping to add another dimension of raw speed to your ride, breaking up the road and saying goodbye to the peloton will leave you in the perfect position come the big sprint finish.Unrivalled SafetyIt’s not just speed that graces your ride when partnering with the Ventral Spin. Unlike many competitors who deploy the MIPS protection system, POC have created their own added layer of safety, a patent-pending rotational impact protection system known as SPIN. Reducing the effects of an oblique fall by limiting the amount of force transmitted to the head and brain, the Ventral also uses innovative and unique pad technology to make this the safest ride you have ever had. Sitting comfortably on your head to shear in each and every direction during impact, SPIN pads provide the ultimate form of protection, moving with the head during any unexpected falls. With the direct force transmitted to the head during falls reduced, POC have inspired your trip with supreme confidence.Lightweight ComfortOffering a helmet so lightweight you’re bound to forget it’s on your head, the Ventral Spin sports a fully wrapped unibody shell construction and an EPS liner for optimised weight and safety. Not leaving a single stone unturned in their quest for greatness, POC’s lightweight adjustment system and ergonomic precision strap allow you to customise your fitting on the go.

Aerodynamic performance, safety and ventilation do not need to come at the expense of each other. By using our whole-helmet approach to development, we have been able to deliver unparalleled levels of aerodynamic performance, safety and ventilation without compromise in the Ventral SPIN. Taking inspiration from the Venturi effect, the helmet’s airflow zones allow the helmet to pass through the air with greater efficiency, making it faster. Residual air traveling around the helmet is managed by the 22° aero trailing edge, the perfect angle for minimizing turbulence, further improving aerodynamic performance. By leading air through rather than around the helmet, its wake is minimized, while its ventilation and cooling properties are enhanced. Other features of our whole-helmet approach include a fully wrapped unibody shell with an EPS liner for the ideal balance between weight and protection. SPIN (Shearing Pad INside), our patent-pending silicone pad technology; a lightweight adjustment system and an ergonomic precision strap provides a flexible, comfortable and secure fit.
