They work by making the head a bit more aerodynamic, making it slip easier through the air. With less wind resistance you get the same speed at less effort, or more speed at the same effort as if you didn't wear a helmet.
And some of them are tested to the same level of impact protection as regular helmets,which can reduce the risk of injury in case of a crash or a fall.
You can buy cycle helmets from either your local cycle shop (which is preferred so it can be sized properly) or from online sites such as 'Halfords', 'Action bikes' or even 'Amazon'.
Much research shows that there is no problem with have stickers on any form of helmet such as ; motor cycle helmets, bmx/shateboard helmets and any other form of crash helmets.
To allow for cooling, so the head does not get too hot.
It depends what type of racing they are doing. In a Time trial there are specific Aero helmets that many prefer. In touring a long distance road riding a light comfort helmet is preferred it's very dependent and also has to do with preference.
Yes, it is scientifically shown that bicycle helmets do work. They help to absorb the impact from a crash and protect your skull and brain.
Very well...
Not all builders wear yellow helmets, but builders generally wear brightly colored helmets...brightly colored to maximize their visibility at the work site, and helmets to protect their heads from injury.
Welders or steel workers use auto darkening and passive welding helmets .
There are many different safety statistics sites online that will show children the safety of wearing helmets. The one I recommend is the CPS website. It is child friendly.
AERO was created in 2004-09.
You can reduce air resistance when cycling by tucking in your body to become more aerodynamic, wearing tight-fitting clothing, keeping your elbows close to your body, and using aerodynamic equipment such as aero handlebars or aero helmets. Riding in a group or drafting behind another cyclist can also help reduce air resistance.
You can adjust the color by right clicking on your desktop and clicking "personalize". You must have the proper graphics card and drivers to ensure that Windows Aero will work.
