I am looking at purchasing a new helmet and was wondering if anyone can give me some information about helmet shell materials. As far as I can tell, there are 3 main types of materials used:
3. carbon fiber
Is there anymore? And what is the advantages and disadvantages of each?
Lastly, is there any helmet that anyone recommends (I know I'll get a wide array of replies). I am looking in the $200-$300 range.
