Bike helmet in different designs and executions
A bicycle helmet must offer protection and comfort and be as light as possible. But that is not enough for a triathlon or racing bike helmet. Because when it comes to speed, the aerodynamic properties also play a role. The shape and construction of the helmet have a relatively large influence on the air resistance when cycling and thus ultimately on your speed. The so-called aero helmets are therefore designed to meet these requirements.
Bicycle helmet with ventilation
Ventilation openings on a bicycle helmet have a negative effect on aerodynamics. However, it also does not work without ventilation, because otherwise the heat would accumulate on the head. With a good racing bike helmet, the ventilation ducts are therefore designed so that the air resistance during the ride remains as low as possible. There are also well ventilated helmets, which can be supplemented if necessary with a closed attachment. The helmet is then somewhat heavier, but has better aerodynamics. In addition, the attachment protects against rain and sun. If you are looking for a triathlon helmet and equipment, the appearance is not unimportant. Therefore, there are many models in several color variations.
Perfect size and fit
For the right fit, it is advantageous if a model is available in many different sizes. So you can choose a helmet that fits well with your head size. Fine adjustments are also possible for a perfect fit. The padding of a high-quality bike helmet adapts well to your head shape, so nothing pushes or slips. First-class inner pads are also characterized by the fact that they support the moisture regulation at the head. An easily adjustable, comfortable and quickly operable strap closure is also important. Because during competitions the putting on and taking off of the helmet must not take up too much time.
