MET Trenta 3K Carbon Helmet - White Gloss Medium SKU: HE4957

The new MET Trenta 3K Carbon is the most ventilated road helmet ever developed for the toughest races and refined inside the Tube MET's proprietary wind tunnel. Already a winner at the Tour de France and the Giro d’Italia Women the Trenta 3K Carbon is the ultimate expression of a modern road helmet. The air has changed and so has the standard. The helmet features the 3K Airframe 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 ensuring consistent airflow at both high and low speeds. The new construction achieves a 40% improvement in the Virginia Tech test — the world’s most recognized independent safety rating protocol — earning 5 stars and one of the best scores ever recorded. The Trenta 3K Carbon arrives at exactly the right moment made for an era where racing demands more — more speed more control more protection.
