The SPEEDster TC helmet features the brilliant adaptive aerodynamic design that is unique to the SPEED series and delivers perfect aerodynamics.
Adaptive aerodynamics: One of the many tear-off airflow edges on the rear ensures best aerodynamics, whatever the head position.
CASCO-Loc: For quick opening with one hand and remarkably simple adjustment.
Closed sides: Closed side pieces for uninterrupted air flow in the interior and exterior of the helmet (improved elimination of heat and prevention of turbulence).
Available in TWO sizes: Medium (52cm-57cm) & Large (58cm-62cm).
