Shockdoctor - http://www.shockdoctor.com have released a new product that can helps remove helmets in the advent of a serious accident.
It is so simple, but so effective. If any sort of spinal injury is suspected, it allows the Helmet to be pushed off by the internal bladder.
Like a lot of great inventions, its very simple, and yet very clever, and very well priced as well for something that could save your life.
Already major teams and Manufacturers and even the AMA are adopting it as standard equipment http://www.xlnk.me/o
