Optimized for use in a peloton, the tubular rear and internal ventilation channels of the MET Trenta provide 7% less air resistance compared to a traditional design, resulting in top performance during group rides. The NACA ventilation opening and rear deflectors ensure sophisticated airflow management inside the helmet, efficiently cooling your head without slowing you down. Additionally, only 30% of the helmet makes contact with your head, allowing for superior temperature control. Equipped with the Mips-C2 safety system, the Trenta sits comfortably on your head and can effectively dissipate harmful rotational forces in the event of a fall.
