The MET Trenta was created to mark our 30th anniversary year. We wanted to develop a helmet for elite riders , a competitive edge for the best in the sport . The name , of course is the italian for 30. Enhanced forr use in the peloton , the MET Trenta’s tube-shaped tail and internal channeling ensure it performs best when riding in a group offering up to 7% reduction in drag vs a traditional road helmet . Engineered to keep you cool , the front NACA vent and rear deflectors work together to channel airflow through the helmet , without slowing you down . Just 30% of the helmet touches the head , further reducing temperature build up .
