Initially glance, you 'd be forgiven for thinking that the Smith Overtake Helmet could not potentially be aerodynamic. Simply look at all those little Koroyd tubes, sucking air right to your head, cooling you as you ride! But, the engineers at Smith, in conjunction with aerodynamics master Len Brownlie, made sure that the Overtake was competitive on all fronts, consisting of aerodynamics. Over a 40k time trial, the Overtake was only about a second slower than the Specialized Evade, and was over 4 seconds much faster than Giro's Air Attack. Back to those Koroyd tubes, though. They're tiny, extruded, co-polymer tubes that absorb about 30 % more effect than standard EPS foam, and, due to their hollow nature, permit air to flow freely in a way that foam simply can't. On top of that, the microstructures permit less material to be made use of in the construction of the helmet, which amounts to a highly-protective helmet that weighs in at just about 250 grams.
