Do you want to know more about triathlon helmets?
The triathlon helmet is a safety element on the bicycle, along with the glasses and gloves. Although its use is not mandatory everywhere, it is highly recommended and necessary to prevent head injuries in the event of an accident.
The bicycle helmets have a maximum duration of 5 years. After this time, the materials that make up its composition deteriorate, losing or reducing the capacity to absorb impacts and compromising, in this way, the safety of the user. That is why it is recommended to renew them after this time. It is also convenient to change it after a fall or a blow, because, although it does not appear to be damaged nor has exhausted its recommended use time, it may no longer protect adequately because its ability to absorb shocks could have been affected.
How to choose a bicycle helmet?
Choosing a helmet is not easy, since there are many models with different prices. Helmets for children can be purchased from 14 euros. For adults, you can find a good helmet from about 20 euros, although some cost more than 85 euros. A higher price is not a guarantee of higher quality, so to choose a helmet should take into account the following characteristics:
- Safety: the price of a helmet is determined, especially, depending on the material, weight and comfort, but in no case, for the level of security, since all helmets on the market must be approved according to with the European standard EN1078.
- The shell: the high-end bicycle helmets are manufactured by an In-mold process in which the outer part and the polystyrene of the inner part are joined together in a single piece, which increases the resistance against impacts and improves the diffusion of shock energy. If, on the other hand, the housing is stuck with the interior material, there is a greater risk of it coming off. The one-piece helmets are generally more expensive, since their average price exceeds 50 euros, while in the attached models the average price is around 35 euros.
- The outward appearance: striking colors or reflective stripes contribute to better visibility.
- The closing system: the click type, with two pieces of plastic that fit one inside another and open by pressing the sides, are the most practical system. Also check its strength, giving a strong pull to see if it opens easily. Whatever type it is, it must have a padded piece under it that protects the chin from rubbing with the closure and prevents the skin from being pinched when it is buckled.
- The ventilation holes: at first glance it is difficult to check their effectiveness, since this does not depend on the number of holes, but on their design and position. Some carry a mesh that prevents the entry of insects.
- The inner padding: the helmets usually have washable and comfortable pads and, sometimes, microperforated, for a better perspiration.
- The visor: can be put on and easily removed for the sun and the branches of trees. It is very common in mid-range MTB helmets.
How to adjust a bicycle helmet?
The effectiveness of a helmet depends in large part on its being well adjusted at the moment of impact. Therefore, you must use the contour adjustment system. Some models have simple cushions or an elastic band. However, the most precise adjustment is achieved with a plastic ring (rock-lock) that surrounds the entire helmet and fits the size of the head by means of a wheel on the back. This adjustment piece must be attached to the helmet by means of flexible plastic elements.
It is also necessary to adjust the length of the straps so that the helmet can not move, but without being uncomfortable (check that you can open your mouth). Make sure that the regulation system is easy to use and that you do not need to repeat the operation each time you fasten your helmet. Try stretching the straps to see if they give in excessively.
The helmet should be placed in a horizontal position, neither tilted towards the nape of the neck nor thrown over the eyes. When moving the head with energy, the helmet should not move from its position, but neither should it compress the head.
The straps should surround the ears, never cover them. You have to make sure that the helmet does not interfere with your hearing or vision. Always wear it fastened, for your own safety and that of the people behind you.
