Italian helmet manufacturer, KASK, welcomes a new aerodynamic helmet to their 2012 line, the K.31 Crono. This time trial helmet was built to be the best with comfort, fit, design and manufacture (a good portion of their products are hand-made and all built in Italy). The helmet incorporates a unique up-and-down size hinged adjustment system to comfortably cradle the nape of the neck, providing the ultimate fit in terms of precision, comfort and security. The tail of the K.31 Crono forms a vertical fin, like the tail of an aircraft, to reduce drag as the rider lowers their head. And in unfortunate incidents, the strengthening frame helps prevent the helmet from shattering into pieces. Ventilated, non-stick pads keep you cool and the chin pad is made of anti-allergic leather.
