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 peak 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 top-level temperature control. Equipped with the Mips-C2 safety system, the Trenta floats on your head, effectively redirecting harmful rotational forces away from your head in the event of a fall.
