3K Carbon Technology

The construction of the MET Trenta 3K Carbon performs better than any other helmet on the market. The R&D team of MET discovered that the carbon’s elastic modulus allows to reduce the density of the EPS foam by 20%, without affecting its capacity to absorb energy. The parallel ‘ribs’ are linked from the centre of the helmet by a carbon cage embedded into the liner, making it dramatically lighter compared to a traditional construction. The result is a lightweight, yet better-performing shell that sets a new standard in terms of ventilated helmet manufacture.

Naca Vent

Originally developed by NACA, a precursor to NASA, the position of this inlet at the front of the helmet has a cooling effect. Harnessing the power of the Venturi effect, the vent pushes out the warm air within the helmet through specially positioned exhausts. This ensures constant airflow through the helmet, without catching the wind and creating drag.

Rear Deflectors

The back of a helmet has a huge impact on how well ventilated it is, with the exit of warm air from within a key priority. The MET Trenta features a flat rear deflector inclined at 25°, which makes it possible to include two wide exhausts that optimise airflow when you’re on the drops and riding hard.

Tube-shaped Tail

The tail of the helmet also has an aerodynamic purpose. It works in synergy with the NACA front vent and the rear deflector to effectively drive airflow. It has a lower profile at the rear, which we developed thanks to specific wind-tunnel testing in the NEWTON laboratory of Milan.

Head Contact Surface

MET built the Trenta in such a way that only 30% of the head will be in contact with the helmet when you’re wearing it. This allows the other 70% to benefit from the optimised airflow passing through the internal cavity, keeping you cooler as you ride.

Fit System

  • All-round belt offers 360° adjustment
  • 4 positions for vertical adjustment
  • 2 positions for occipital adjustment
  • MET USB LED light compatible

Nachdem mich mein alter Helm, bei einem Sturz mit kompliziertem Schlüsselbeinbruch, vor schlimmeren Schäden bewahrt hat, musste ein neuer her. Da ich bei meiner Kopfform immer Probleme hatte, einen gut sitzenden und optisch anprechenden Helm zu finden, habe ich MET erstmals ausprobiert. Eine Offenbarung! Der Helm ist superleicht, lässt sich perfekt anpassen, und sieht grandios aus.
Отличный шлем, очень красивый и невероятно легкий!
На обхват головы 53,5 см размер S подошел идеально. Легкий и очень красивый.
Stunning helmet. small. light, very comfortable.
Adjustments, are very easy, and you can adapt it a lot, sideways, height.
Bought also, the back led light and the front Duagel pad.. very interesting product. will recomend it.
