MIPS is a sliding plane system within the helmet designed to slow or prevent the amount of energy that is transmitted to or from the head. Lots of safety certifications, enhanced protective features, well ventilated, deep fit with lots of coverage We majorly appreciated the extra coverage and protection of the Tyrant when things got rowdy, but it also comes with a weight penalty. This model is far heavier than your standard half-shell trail helmet. It doesn't make you feel like a bobblehead like some of the heavier full-face helmets out there, but you'll undoubtedly notice it has more heft than your average lid. Given the intended purpose of this helmet, we don't think the extra weight is a major issue. The Tyrant is perfect for having fun on the trails and testing your limits with the peace of mind provided by the protection from added coverage. Still, you may also prefer the lighter weight and ventilation the protective Kortal Race MIPS offers.

I have previously owned the Specialized Ambush MIPS helmet weighing in at just 278g for the size medium. The Sixer is 410g for the size medium so the weight difference was definitely something I had to get used to. Weight wise, the Ambush is unmatched in the category but I always questioned it’s reliability in a major crash. Over the last several months of riding, I have been able to put the Sixer through every situation. Well almost. Thankfully I haven’t taken a direct hit in the helmet. Instead I let Drew handle that end of the testing. Despite carnage to other parts of his body, what’s left of his brain seemed intact and un-rattled – impressive considering his dive. As part of a new wave of moto-inspired, open-face trail helmets, the Giro Tyrant Spherical provides significantly more head coverage than most of the standard mountain bike helmets we tested. Giro bills this beefy lid as a versatile option that can span the gap between gravity, trail, and dirt jump helmets. After weeks of rigorous testing, we support Giro's claim that it's an incredibly versatile helmet despite its heavy, protective construction. The first thing you'll notice when donning the Tyrant is that it shares a unique dual-shell construction with its half-shell counterpart, the Manifest. The inner shell is low-density EPP foam for minor impacts, and the outer shell is high-density EPS to absorb major collisions. Despite its double-shell composition, the helmet keeps a relatively low profile on your head, and the vents do a surprisingly good job of keeping things cool. Combine the innovative protection and coverage with Giro's Roc Loc harness system and refined shell shape, and you have a helmet that stays comfortable all day. Reasons to avoid: Old-style clasp, visor fixing screws can work loose, rear coverage less than competitors A visor's primary function is to shield your eyes from the sun, but they also serve as a little protection from rain and can help to deflect less consequential trailside obstacles. Helmet visors vary in size and shape, as well as in attachment method and adjustability. Many visors are adjustable and can be articulated up and down to improve visibility or accommodate goggles. Others are static and fixed in the lowered position. Our gear testers prefer adjustable visors for their versatility and so that they can better accommodate goggles.

Whether pinning the berms or taking in the sights, welcome the perfect level of protection with the Sixer MIPS Helmet from Bell. If you find an item at a lower price with another commercial internet retailer, you will receive it from us at the same price, provided the conditions listed in the link are met.

Always at the forefront of helmet design, Bell’s Sixer brims full of tech and provides a superlatively comfortable fit. Varying densities of foam are used to build up the structure of the Sixer, each one optimised to absorb different impact velocities. Progressive Layering utilizing two layers of foam: a hard layer against the outer shell closer to the point of potential impact, and a less dense layer closer to the head. Each layer has a thin hard shell molded into it. Integrated breakaway camera mount requiring no zip ties or tape, designed to break away upon impact to reduce the risk of injuryIn the in-mold construction, the robust polycarbonate outer shell is bonded to it in a single pass during foaming of the impact absorbing EPS inner shell. This makes the helmet even more resistant without any additional weight. This production process also makes it possible to form significantly better ventilation systems and openings. In-Mold helmets are lighter than traditional helmets and have much better ventilation systems.
