The Z1 FAST helmet has an integrated and non-removable cover that is attached to the EPS liner, to create an unbeatable advantage. Because of the one piece shell, it has a better distribution of impact forces.
In addition to improved impact distribution, the Z1 FAST has a distinct advantage over a regular road helmets, aerodynamic performance. The shell closes of most ventilation holes, thus it creates a surface that glides through the air with significantly less resistance. Tests have proven that the Z1 FAST helmet can provide gains between 4 and 10 Watt when cycling at 45 kph, or a difference between 12 and 30 second over 40 kilometers. That could be the difference between standing around watching the podium ceremony versus being on the top step!
