The structure of Kranium has been developed to absorb the impact energy. The ribs of the structure have been designed to accommodate movement in some places where as it remains perfectly rigid in some areas. Thus during a crash the force peak of the impact is absorbed by the ribs tending to flex and de-flex. The remaining amount of energy is then absorbed by the crumpling nature of the corrugated ribs. When tested against the British Standards (EN 1078) at the Imperial College, Kranium absorbs more than 3 times the amount of impact energy when compared to regular cycling helmets. This means that during a crash, lesser amounts of energy go into your head thus making it safer than regular cycling helmets.
Kranium has also proven to last more than one impact. During the testing phase the same helmet has been tested 5 times consecutively and it still proved to pass the standard. Polystyrene helmets however are rendered useless after a single impact. It has also been impregnated with a compound to make the cardboard water-proof.
