Casco Speed Time Trial Helmet

The aerodynamics of the Casco Speed Time Trial Helmet adapts to the body position and the posture of the athletes head. Even in the heat of the race when you fight and your body position is not ideal SPEEDtime is uncompromisingly streamlined and delivers top aerodynamics no mater what position your head is in.

You can mobilise your complete physical reserves without taking any aerodynamic disadvantages. On the one hand this is possible by the air spoilers at the rear edge of the helmet, which significantly reduce the flow resistance. On the other hand the patented air guidelines on the outer shell of the helmet optimise the air stream. In addition the sophisticated double-shell construction supports the unprecedented streamline design of the helmet.

Thanks to its large dimension across the face and ears, the SPEEDmask provide best aerodynamics and prevents slowing air vortex formation. The head of the SPEEDtime wearer does not contact the helmet shell. It only has contact with the helmet through a tensed net. This ensures a very good fit and provides excellent heat removal. The closable front opening allows additional air to enter into the helmet, flows around the head and streams outwardly through the ventilation slots on the rear. With this variable and highly efficient ventilation system the helmet is suitable for flat short and long distances such as triathlon or time trial.

Sizing: Uni - 55-61cm
