[QUOTE="tx246, post: 285605, member: 23127"] [b]lemme clarify[/b] patman, i agree with you on everything you have said. helmet builders will tell ya that they slow your head down with the styrofoam. the shell is there to protect the foam and prevent punctures to the foam and head. i dont mean to imply we should ride around in bicycle helmets. did your mountain bike buddy hit his head on something that might puncture ie a rock? that styro shell is supposed to break up. if it broke up from the outside due to a puncture from a rock than yes a fully shelled foam would of been better. people on trials i think would take your view as there are lots of things hanging around that would punch holes in a bicycle helmet. besides bicycle helmets have no face/jaw protection. they say the ultimate helmet is: light......to protect against whiplash strong(shell)............to displace loads that might puncture the shell and comprimise the foam and/or actually make it your head got full jaw coverage and finally.........uncomprimised foam liner to decellerate your head i guess the bottom line for helmet shells is this. strength is good for impact resistance to protect the foam. in itself the shell protects the foam so it can take the force of the head and decellerate it in a controlled manner. i feel that most people consider the shell as the most important part when in fact it isnt. if it was proven that the shell alone did the protecting, then we would all ride around in old army helmets. to be honest with you i think the manufacturers should do more research in the foam end of the helmet.
