Two years ago helmet manufacturer Giro defied established genres by launching the Air Attack. It attempted to blend some of the the ventilation benefits offered by a traditional road helmet, with the aero performance of a TT lid, without sacrificing comfort or performance.
Taking that design ethos one step forward, the new Giro Synthe attempts to blend the aero benefits of the Air Attack, with better ventilation, to produce the ultimate road helmet.
In wind tunnel testing, the Synthe was the most aerodynamically efficient road helmet Giro has ever produced. The acclaimed Air Attack still has the edge when tucked, and a dedicated TT helmet like the Selector will still be the go to choice for Tri-Athletes, but the Synthe offers the best performance advantage when riding in a more normal upright position.
In addition to being almost as aerodynamic as a dedicated TT helmet, the Synthe is the best ventilated helmet they’ve ever tested, due to elaborate internal channeling that pushes air through 19 massive vents.
Utilizing a head form covered in temperature sensors and heated to the same temp as a human body, Giro found that the Synthe outperformed the Aeon (which has five more vents) for cooling prowess, but nearly matched the cooling performance of the bare head form.
The new wonder helmet weighs just 250g, offers a fully adjustable retention system, has a sunglasses docking feature.
Helmets will be available this Fall, in seven standard and one limited edition colors, for an MSRP of $250.
