What is the best type of adult bicycle helmet for a decent price?




sammypj


wondering if it is worth it to by one at a bike shop for $50+ or target for $20?


Answer
It matters in one key area...comfort and/or ventilation. Summer is here. Your head will need to vent from as many directions as possible. Most cheap helmets only have vent slots on top. Better ones will have vent slots on the top & REAR! You can find a really good Giro helmet on Amazon.com for $40 or less with free shipping.

what is the structure of the bicycle helmets?

thanks very much



Answer
ive attached a picture that shows the ventilation of a modern helmet, i couldnt find anything that shows the structure.

basically, a helmet is a foam inside with a plastic shell. the idea behind this is that when your head impacts something hard (like the ground) the foam will be crushed and absorb the impact. some expensive helmet (Giro Atmos) are built with a carbon fiber rib cage which enhances the durability of the lid. carbon will tolerate some flex before it breaks and helps transfer the impact throughout the helmet instead of one spot.
