Why are not use to the more expensive helmets after a crash?
This can be explained with the construction of the shell (in-mold technology) . This is made of resilient polyester foam and is fused with a very thin plastic upper shell in the manufacturing process. The shell acts in a very stiff and remains so, as long as there is no force acting on a specific location. If, namely this, and it is usually in a fall the case, the applied force is distributed over the shell lattice. The skull gets the impact energy in the form of a distributed pressure is felt. This can indeed be painful and in severe cases, concussion , But he will almost never cause serious head injuries.

But still: The helmet is unfortunately broken after a fall. He does not have to be broken into two parts. No, there are hairline cracks in the polyester foam, which can often be seen on the surface. What you can not see, the internal "injuries" of the bicycle helmet. In any case, the helmet can not protect everything in a second fall the head, are acting as the impact energy no longer distributed over the composite shell and steamed it can. It will be at near full strength on the skull . Pierced And if it is running very unhappy, fragmented the shell and injured his head at that.
