MET Trenta 3K Carbon

TRENTA 3K Carbon


For thirty years MET has been making helmets for the very best in the sport of cycling. 
We’ve learned, refined and developed our products, getting faster, lighter and more comfortable with every generation.  
We created the MET Trenta to mark this milestone year.

MET's 30th anniversary

Now, there’s a new member of the family, a new standard in helmet design, 
a new competitive edge for the world’s elite.

MET Trenta 3K Carbon


The construction of the MET Trenta performs better than any other helmet on the market.

Our R&D team discovered that the carbon’s elastic modulus allows us 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.

Enhanced for the Peloton 


Met Trenta

The MET Trenta is a performance road helmet for elite cyclists. 
Looks and performs best when riding in the bunch, engineered to keep your head fresh and save you energy with every pedal stroke.


3K carbon construction | Weight: 215 g (size M) | 19 vents | Proven drag saved: 7% at 45km/h


Designed & Engineered in Italy



Originally developed by NACA, a precursor to NASA,  
the position of this inlet at the front of the helmet has a cooling effect.

See more about Venturi Effect

Harnessing the power of the Venturi effect,  
the vent pushes out the warm air within the helmet through specially position exhausts. This ensures constant airflow through the helmet, without catching the wind and creating drag.


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.


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.


We built the MET 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.
