    *Helmets begin with ideas, which lead to a sketches, which lead to half-scale models made first of foam and then of clay. The models allow engineers and designers to quickly and easily revise helmets before committing to full-size prototypes.* Photo: Peter McCollough/Wired

    *When Giro developed helmets for Lance Armstrong's Tour de France campaigns, it made a life-size model of his torso to refine his [$15,000 time trial helmet](http://stag-komodo.wired.com/playbook/2010/07/armstrong-helmet-exclusive/) in a wind tunnel. The Air Attack shares the frontal profile of a time-trial helmet.* Photo: Peter McCollough/Wired
