If you are going to buy a helmet, here are some considerations when purchasing and using it:
Materials-Basically helmets are made in two parts: A plastic protective film or housing and interior(which surrounds the head) in expanded polystyrene(Styrofoam).
The outer film protects the polystyrene from natural wear(sun, rain, friction and moisture), keeping the assembly together and compact, as this material tends to form small cracks.
Polystyrene is the most important material of the helmet, since it is in charge of absorbing the impact, flattening first and then breaking.
If the speed is 50 kilometers per hour, for example, the helmet will make the impact equivalent to that of a fall at 45 kilometers per hour, it will also prevent cuts and bruises on the scalp(not insignificant) and distribute the impact force By a larger area of the skull. It’s like saying that it would be the difference between getting hit with a hammer or with a pan.
Types-Of hard shell or soft shell(also exists without shell, but almost no longer manufactured). Against the blows are more effective those of hard carcass, that on the other hand are less ventilated. Its use is practically inviable in long pedaladas. The hard-shell helmets are common among those who practice extreme maneuvers and adepts of free ride and downhill modalities.
Helmets can be manufactured with in-mold technology or not. The former means that polystyrene is manufactured directly on the outer shell as if it were a mold. So both pieces fit together, getting solidly together. The other way of doing the helmets implies that the parts are manufactured separately and come together later, which makes the helmet a little less robust. Currently most helmets are manufactured with in-mold technology.
Quality vs. price-The most expensive helmets are not necessarily the safest. The price of helmets depends on issues such as their weight, ventilation, whether they have visor or not, adjustment systems and course, helmet design.
The cheaper helmets cost around 40 reais and can reach 800 reais, which are some super sophisticated models. The price does not necessarily indicate greater security. Every homologated helmet should work well, the difference is in the other characteristics that we mentioned above.
Sizes-Helmets, like almost everything in life, come in different sizes depending on the circumference of the head. Traditional sizes are for heads with circumferences between 50 and 62, depending on manufacturers and models. For example, my head has a circumference of 56cm and this equals an ‘M’ of the brand Giro, which is worth for heads between 55 and 59cm due to the circumference regulation that has on the helmet.
The best way to know if the helmet is the right size for you is by experiencing it. Currently, most helmets come with a sort of adjustment strap to fit the head better.
Adjustments-For the helmet to protect your head as it should, it must be adjusted correctly. That is, the edge of the hull should be one or two fingers above the eyebrow so that when you look up you can see the edge. The belt must be tight. Ideally that which is less than 4 inches apart between the strap and chin, and the side of the strap should make a ‘V’ lightly leaning against the skin. The final result should be a firm but unscrewed helmet.
This is the test to know if you did it correctly:
- When you open your mouth, does it squeeze your head? Open your mouth as big as if yawning. You should feel how hard the helmet is pressing on your head. If you feel any discomfort you should loosen and if you do not press anything you should tighten the chin straps.
- Can you easily move the helmet back and forth? You should adjust the adjustment strap first, and then the chin straps until the helmet is firm.
For those with long hair, a trick: you can help keep the helmet in position by making a ponytail and passing in the triangle that makes the adjustment strap and the helmet itself. Depending on the height of the ponytail the helmet will be well positioned.
Miscellaneous advice-Helmets have validity, as do yogurts. Over time the polystyrene loses elasticity and no longer protects sufficiently the strokes. As a basic guideline, we can say that the average age of validity of a helmet is 5 years, but it depends on the make and model.
When the helmet receives its first strong impact it also ceases to be functional: the material loses tension, and will not react correctly when it has another impact. In that case, if you have had a considerable crash, replace the helmet.
For cycle tourism we recommend helmets with visor(flap). In addition to protecting against the sun, they also prevent heavy rains from directly
