Looks really cool Bill but it's not for me. I fall off my bike at least once a week and it would just busted in the wreck. Maybe it would be a good idea for riders that aren't plagued with vertigo and poor vision but kerf would tear it up quick.
I hope you guys realize that it was posted with 'tongue in cheek'
that was were the 'not-so-hardcore' part came from
the new DH mtn bike on the side of that page looks pretty cool tho
