The Casco Speed Time Helmet design with uncompromising aerodynamics. No helmet delivers better times on short and long distances time trials and triathlons. The aerodynamics of the Speed Time adapts to the body position and the posture of the athletes head. Even in the heat of the race when the sportsman fights and isn't in an ideal body position the Speed Time Helmet is uncompromisingly streamlined and delivers top aerodynamics.

This helmet enables the cyclist to mobilise his 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 of the athlete the visor provides the best aerodynamics and prevents air vortex formation. The visor also enables even from the lowest position a trouble-free field of view. The head of the Speed Time wearer doesn't 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 closeable front opening allows for additional air to come into the helmet, flowing around the head of the sportsman, and streaming outwardly through the ventilation slots on the rear again. With this variable and highly efficient ventilation system, the helmet is suitable for flat, short and long distances such as triathlon or time trial.

Key Features:

  • Adaptive since the aerodynamics adjust to the athlete’s body position and head posture delivering outstanding performance in any position
  • Helmet shape to promote airflow through sophisiticated double shell construction
  • Multiple break away edge on rear custs air resistance
  • Flow channels optimise air flow
  • Sealable front inlet for personal ventilation preferences
  • Special contactless fit using tensed net
  • Size: Unisize 55-61cm
