Since its debut in 2017, the MET Trenta 3K Carbon has been refined through thousands of test hours, race days, and, yes, real crashes.
2025 sees the brand introduce its latest iteration of the helmet, “created in close collaboration with Tadej Pogačar, UAE Team Emirates XRG, and UAE Team ADQ.”
With the arrival of this latest version, we are told that “The goal was never incremental change. It was to push airflow and impact protection to a new level while keeping the helmet intuitive for riders at full effort.”
Headline details
- Ventilation: Increased by 16% thanks to a reworked internal geometry and optimised air channelling, engineered within MET’s proprietary wind tunnel.
- Protection: Safety performance is up 40% in independent lab testing for linear and rotational impacts, earning a 5-star Virginia Tech rating.
The new Trenta 3K Carbon, “chosen by riders who know that safety and performance are the same thing,” has already taken wins at the UCI Road World Championships, the 2025 Tour de France and Giro d’Italia Women.
MET points out that “The Trenta still feels minimal, but its structure now reacts better when speeds are high and crashes come hard.”
3K Airframe
The new helmet features a carbon wing structure that eliminates EPS from the internal frame. The result is a continuous internal air channel, uninterrupted from the front intake to the rear exhaust.
With a 16% improvement in airflow compared to the previous generation, it sets a new benchmark in ventilation, aerodynamic management, and comfort.
At its core is the 3K Airframe: a carbon wing structure that removes EPS from the internal frame with open air channels. Air moves freely from the front intakes to the rear exhausts – you can almost see straight through it. It’s a quiet piece of engineering that keeps the head cool whether climbing at 12km/h or descending at 90.
Protection isn’t theoretical
The new construction achieves a 40% improvement in the Virginia Tech test — the world’s most recognised independent safety rating protocol — earning 5 stars and one of the best scores ever recorded.
Every year, MET receive between 20 and 30 crashed helmets from the team — most of them showing clear signs of high-energy impacts. This means almost every rider of a World Tour Team experiences at least one high-speed crash per season, which is why minimising the risk of concussion is a top priority, at the same level as performance.
