The POC Myelin is a helmet unlike any that's ever been on the market in the past. From a style standpoint, it's a commuter helmet and it's unique even if you don't go farther than that. The outer shell uses a fabric covering and there's no adjustment to the rear cradle. The look would pair well with something from Chrome or Mission Workshop but there's a lot more to it beyond what you can see. The TS+ is used on mid-level road, mountain bike, recreational, and kids helmet models. Adjustable Head Basket Start by measuring your head with a fabric measuring tape. You want to place it across your brow and above your ears. If you don't have a soft measuring tape then use a piece of string then compare it to a standard measuring tape. I've even used a long USB cable in a pinch. Polycarbonate Roll-Cage - The helmet foam is sandwiched around an additional polycarbonate layer during construction. In the same way as the roll cage of a rally car, this layer keeps the foam together after a crash providing additional protection in the event of additional impacts. system providing vertical adjustability and the exclusive KinetiCore protection technology, and the result is an

Lazer Aeroshell Compatible - The Sphere is compatible with the Lazer Aeroshell accessory. Snap on the Aeroshell for improved aerodynamics and protection from the elements. The big difference between the two is that Smith adds Zonal Koroyd in addition to MIPS. Koroyd looks a bit like a handful of straws and the idea is that it actually replaces some of the foam to add rotational impact protection right into the helmet itself. There's another interesting effect of the Koroyd though.

OFF-ROAD

The inconspicuous design of the helmet makes sure it is at home wherever you take it. An in-mold construction is used Sleek and comfortable - Tonic KinetiCore is designed for the recreational road cyclist who wants a lightweight helmet When it comes to finding a comfortable budget bike helmet, it's all about fit. You could say the same about more expensive helmets as well but it becomes even more important as other features get stripped away. Different brands have different size ranges and some fit perfectly while others are a struggle.

The real star though is the rear cradle. The design is the same as products like the Giro Eclipse aero helmet and that means it's compatible with the Roc Loc 5 LED light. It is an added cost but it's the most integrated rear light I know of on a road bike helmet. The Agilis also adds reflective paint that's effective even without a light. One way to approach the idea of budget is to look for a helmet that's highly versatile. If you commute by bike during the week and then go for longer rides on the weekend, it can be difficult to find the right helmet for both situations. A lot of people solve the problem by having more than one helmet. Bontrager has another idea though. Virginia Tech tests helmets from a wide variety of sports and has been doing so since 2011. No helmet brand is able to pay for better results and there is a standard testing protocol. If you do decide to keep an eye on the testing results of Virginia Tech, you'll need to understand what they mean. to improve airflow when you’re pushing your pace. Once the temperature drops and cold wind is no longer welcome, the There are a variety of reasons that a good helmet might not have MIPS. For one thing, as already mentioned, not every company agrees with the need for a slip-plane system for safety. There are also other companies that do agree with the need but would rather develop a unique system of their own. Some of the technologies that replace MIPS are WaveCel from Bontrager, Kineticore from Lazer, and Koroyd which Smith uses.MIPS outfits a helmet with a low friction layer that reduces rotational forces in case of a crash. This replicates the brain’s own protection system. Bottom Shell - Polycarbonate bottomshell finishing looks great and helps protect the helmet foam from cosmetic damage. Given that those are all important for evaluating a helmet, we've included the scores when available. If you are looking for a helmet, it's reasonable to consider that score but you might also choose a helmet that doesn't have it. Not every helmet has been through the testing and there are valid reasons that might have nothing to do with performance. When it comes to the downsides of the Circuit, it centres around the WaveCel rotational impact system. Unlike Kineticore which actually adds breathability, WaveCel is a system of cells that cuts down on breathability somewhat. I've never found that to be a big deal but I have found myself bothered that I can't reach through the vents and scratch my head. I also would always prefer a lighter helmet over a heavier helmet MIPS stands for multi-impact protection system and it's a brand name. At this point, it's become synonymous with helmet safety because MIPS was early to identify the need for a slip plane system to reduce head trauma. The brand is the most well-known because of its excellent marketing and smart technology. That doesn't mean though that a helmet has to have MIPS to be safe.
