Alpinestars Bionic Neck Support Sb X-large Black

Alpinestars Bionic Neck Support Sb X-large Black
The Bionic Neck Support SB or Special Blend is constructed of polyurethane that is strong enough to support impact even at sub-zero temperatures. This structure works with the helmet in attempt to reduce the severity of a catastrophic neck injury. It functions by providing an alternative load path when the neck is compressed. If the helmet is in contact with the neck support at the moment of impact the overall load passing through the neck can be reduced, which may prevent a fracture from occurring. Patented Pivot Key System: A special magnesium key located at the rear allows the convenient front opening of the devise while also allowing it to be dismantled in an emergency. Patented Fitting System: Fine adjustment of the shoulder height allows a more personalized fit. Patented Rear Stabilizer Failure System: In the event of large loads being channeled onto the rear stabilizer (the part that sits on the back), there are a number of deliberate bending and facture points designed to relieve extreme loads that may be transmitted down the back. Collar Bone Preservation 1: All parts in contact with the body use an expanded foam compound to distribute the impact force over the widest area yet remain light in weight. Collar Bone Preservation 2: A continuous frame member runs over the shoulders - this means there are no weak points in a critical part of the frame, and that there are no metal pins or screws sitting directly above the shoulder which could be dislodged into the shoulders or collar bone during an accident. Choice of Strap System: The Bionic Neck Support is supplied with the new X-Strap System which allows a smaller, lighter strap (worn over or under the jersey) to secure the device to the rider. The larger A Strap assembly (sold separately) provides a traditional chest strap for those who like to wear the protector tight to the body. Carbon Composite frame to achieve the best stiffness with the lowest weight.
