With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

Met Trenta 3K Carbon Airframe MIPS Helmet in Opal Gray

Season:All Year Round

Brand:Met

Code:METROAD5TRENTA3KOG

The MET Trenta 3K Carbon Airframe represents the pinnacle of modern road helmet design, engineered for the highest level of racing performance. Developed in MET’s proprietary wind tunnel and tested in the world’s toughest competitions, it delivers unmatched ventilation, aerodynamics, and protection.

Created in collaboration with professional riders including Tadej Pogačar and UAE Team Emirates, this helmet has already proven itself at the highest level, with victories at the Tour de France, Giro d’Italia Women, and UCI World Championships.

At its core is the innovative 3K Airframe — a carbon fibre structure that reduces the amount of EPS foam while creating a continuous internal air channel. This design maximises airflow from front to rear, ensuring consistent cooling whether climbing, cruising, or descending at speed.

Safety is equally advanced, combining this construction with MIPS Air® rotational protection to achieve a 5-star Virginia Tech rating and one of the best scores ever recorded. The result is a helmet that not only performs aerodynamically but also delivers industry-leading protection.

With optimised fit, reduced contact points for improved airflow, and refined strap systems, the Trenta 3K Carbon is built for riders who demand the very best.
