Kask Caipi MTB Cycling Helmet (WG11)Highly protective, thanks to its technical construction, lightweight, at just 250g, and well ventilated, with a total of 22 vents, the Kask Caipi MTB Cycling Helmet (WG11) is ready to roll with you on any mountain bike escapade. Trail-Ready ProtectionAs you drop into technical trails, rip around big berms and revel in the thrill of taking on challenging terrain, the Caipi MTB Cycling Helmet will give you confidence that should you take a tumble, your head is well protected. In order to protect you in the event of a fall, the Caipi uses Kask's innovative MIT design. MIT uses a polycarbonate shell fused to an impact-absorbing inner EPS liner. By directly joining the layers together shock absorption is improved. An extended rear section to the helmet boost all-round protection too, covering you to the base of the skull. The integrated peak keeps the sun off, spray out and brushes off trail-side debris.Thanks to the strength of the MIT construction, Kask have also been able to optimise ventilation without compromising safety. The 22 vents of the Caipi ensure your head doesn't suffer from getting too hot and the Sanitized® antimicrobial padding keeps things fresh and prevents an itchy head after a day's riding. WG11 Safety TestThe Caipi passes the stringent WG11 test. This focuses on protection from rotational impact forces, measuring rotational kinematics from both oblique and normal impacts. With this safety test passed, you can be sure the Caipi has you covered should you be unfortunate enough to fall from your bike. Kask Octo-FitThe Kask Octo-Fit offers both excellent security and a precise fit. A rubberised Micro Dial adjuster provides an improved finger grip for adjustment. Floating cradle contact and supports are designed to oscillate freely through 180° allowing a perfect fit on any shaped head. The Skeletal Brackets of the cradle have been designed and refined to provide the best fit and support whilst being as light as possible.Features:MIT protection technology - full polycarbonate shell coverExcellent ventilation with 22 ventsGenerous protection and head coverageThermoformed paddingOcto Fit adjustment systemCustom-fit divider on strap for optimal fitLightweight polypropylene visor with integrated ventilationPasses WG11 International Safety Test and CE-EN-1078, CPSC 1203AS/NZS 2063Weight: 250g (M)Buy Kask Helmets from Chain Reaction Cycles, the World's Largest Online Bike Store.

Kask Utopia Road Cycling Helmet (WG11)Engineered to deliver uncompromising aerodynamics, the Kask Utopia Road Cycling Helmet (WG11) is fast. But it's safe too, passing the tough WG11 test for safety, keeping you protected from direct and rotational impacts.Kask set out to create a cycle helmet suited to the high speeds of racing, with smooth airflow and excellent ventilation as key drivers of the design. Using wind tunnel testing and computational fluid dynamics (CFD) simulation, Kask have succeeded in creating a helmet with unrivalled aerodynamics while retaining incredible ventilation and safety. Compared to the competition the Utopia resulted in a saving of up to 6 watts when riding at 50kph. It may not sound significant but every little bit of saved energy is vital when going for the win.While aerodynamics were the primary concern, Kask didn't overlook ventilation. Using the data from their testing the design and engineering team have been able to optimise airflow so that you can use the Utopia all year round, even in warmer conditions.

Kask Wasabi Aero Road Helmet (WG11)The Kask Wasabi Aero Road Helmet (WG11) brings together smooth aerodynamics and a unique sliding panel to let you regulate temperature and airflow to meet the demands of the weather and your ride. While the Wasabi Aero Road Helmet (WG11) is certainly streamlined, second only to the Utopia in Kask's wind-tunnel test, it's how it lets you regulate airflow and temperature where it excels. Aero. Warm. Cool. You ChooseThe Wasabi Aero tackles heat regulation via an innovative sliding front panel. This lets you maintain low-drag performance as the pace increases or you can boost or restrict airflow as and when needed. Closing the vent keeps your head warmer during colder weather conditions, ideal for winter training and early season racing. But pop it open when the heat rises and you have more cooling airflow.Even with the sliding panel open, the drag increase is minimal (with a claimed 1-watt drag increase at 50 km/h). But this helmet isn't just about heat regulation and aerodynamics, your comfort and safety are of course key characteristics too. WG11 Safety TestThe Wasabi Aero passes the stringent WG11 test. This focuses on protection from rotational impact forces, measuring rotational kinematics from both oblique and normal impacts. With this safety test passed, you can be sure this helmet has you covered should you be unfortunate enough to fall from your bike.Naturally ComfortableInside the helmet, you'll find pads made with merino wool. These pads are excellent at regulating temperature and wicking away moisture, boosting comfort whatever the weather. And with natural bacterial resistance, itchy scalps and nasty smells are prevented. Kask Octo-FitThe Wasabi uses Kask's super-adjustable Octo-Fit system for a perfect fit every time. A rubberised Micro-Dial adjuster provides easy adjustment with a quick twist. Meanwhile, the floating cradle features contact points and supports designed to oscillate freely through 180°, allowing a secure fit on any shaped head.
