Misconception 1: The lighter the helmet, the better
Relatively speaking, the lighter the helmet, the better. But the lighter the cycling helmet, the less likely it is to pass the national safety certification testing standards, and the higher its relative price will be. So the prerequisite for choosing a helmet is to pass the national safety certification test standards. Most helmets priced above 200 yuan can reach around 260G, and this weight will not make you feel tired even if you travel long distances, so there is no need to pay too much attention to the weight index of the helmet. Unless it's for a bicycle race. Try to reduce your own weight as much as possible, otherwise it's not worth spending extra money on a lightweight helmet.
Misconception 2: The larger or more holes in the helmet, the more breathable it becomes
Breathability is the key to a helmet, ensuring that your head is dry during long-distance cycling. The more or larger the ventilation holes on the helmet, the greater the airflow around your head, and the cooler you will feel. However, please remember that the more or larger the ventilation holes on the helmet, the more exposed your head will be, so the degree of protection will correspondingly decrease. Compared to mountain bike helmets, road bike helmets have more or larger ventilation holes. Similarly, compared to mountain cyclists, road cyclists need to consider the weight factor of their helmets more. Generally speaking, the lighter the weight of a helmet, the more expensive it is. Therefore, unless you are competing in a bicycle race and want to minimize your own weight, it is not worth spending extra money to purchase a lightweight bicycle helmet.
