BELL Avenue MIPS Adult Road Bike Helmet

Product Information

MIPS stands for Multi-directional Impact Protection System, which is a leading slip-plane technology inside the helmet designed to reduce rotational forces that can result from certain impacts. Others, such as Lazer, have come out to say they support rotational injury standards and, beyond cycling, FIM (Fédération Internationale Motorcyclisme), the motorbike racing equivalent of the UCI, also wants to make it part of its testing. PROGRESSIVE LAYERING—The process of engineering a helmet liner with variable EPS foam densities to better manage the transfer of energies after some impacts. Marcus Seyffarth, head of product development at MIPS, uses the analogy of stretching a rubber band to explain the effect these strain values can have.

We were a small company,” says Halldin. “It takes quite a lot of effort to get your product in different helmet segments. This bike helmet simply refuses to be put into a box—it's part road, part mountain, and part world traveler. It's the helmet that opens up the possibilities for endless exploration. The Mips system is designed to provide added safety for helmets in many accidents. For certain impacts, the Mips system can reduce harmful rotational motion that might otherwise be transferred to the user’s head.There are two analogies used by the team at MIPS to help explain what’s at stake, and why preventing rotational forces from transferring to the brain is important. It’s also worth noting the time frame in which a helmet can actually do something to help prevent serious brain injury is slim. Several well-known bike helmet brands offer select MIPS helmets, but Nutcase, which manufactures stylish helmets for kids and adults, is the first bike helmet brand to fully incorporate MIPS into its lineup. Fit system: Float Fit LED - a lightweight fit system with an easy-to-turn rubber overmolded dial for adjustments (integrated with MIPS)

Some mountain bike helmets feel downright steamy when your head gets warm, but the Bell 4Forty MIPS Bike Helmet keeps discomfort at bay with several thoughtful features. Whether you’re grinding it out on some seriously technical trails on your e-MTB or exploring new terrain at your local park, innovative Sweat Guide material draws moisture away from your brows and eyewear. You’ll also find 15 vents for optimal airflow. The Super Air is the first trail helmet to offer Flex Spherical + MIPS, making it our most advanced trail helmet. Period. This combination of outstanding safety, optimized ventilation and extreme lightness brings epic achievements within reach — on any trail, in any terrain. When you’re ready to step up, upgrade by adding the optional chin bar. See you on the trail!Every helmet on this list does just that, if not more, and should at least offer your head some protection against bumps and scratches if you fall off your bike while out riding. We rate each bike helmet based on the results of 24 impact tests in our laboratory. A drop tower designed to match helmet-to-ground characteristics in cycling is used to test the helmets. We measure linear acceleration and rotational velocity for each impact, which are correlated to concussion risk. A helmet that fits properly can reduce the risk of injury during a crash, which is why Specialized has selected a micro-dial fit system with height adjustability. There’s even a HairPort to keep cyclists with longer hair safe and comfortable.
