A new time trial helmet called Selector has been released by Giro for 2012. Coming with two aerodynamic lowers, the Selector allows riders to choose between different depths for the bottom section at the back, which are 10mm and 45mm.

Between the helmet and the back of the rider, there is no drag-causing gap. Drag is prevented since there are no front vents in the shell of the helmet. However, at the top of the removable visor, the little vents go straight to some deep channels in the body of the helmet.

In turn, the deep channels remove the air to wear out ports at the back, providing a steady flow of air over the rider’s head. Being one of the fastest production aero helmets on the market today, the 2012 Giro Selector Time Trial Helmet comes at a quite expensive price tags.
