3T Extrema Italia Frameset

The 3T Extrema Italia Frameset, produced at 3T's state-of-the-art Italian facility, joins the brand's latest lineup alongside the Racemax Italia. While the Racemax caters to swift courses and mixed tarmac/gravel rides, the Extrema lives up to its name, designed for the toughest race circuits and high-speed adventures. Sharing advanced carbon production technology with the Racemax, the Extrema distinguishes itself by incorporating adventure-focused features, providing a comfortable and capable ride without compromising on speed and performance. With leading tire clearance accommodating 700c/29” wheels, triple mounts for enhanced bikepacking, and a versatile design for both electronic groupsets and wireless dropper posts, the Extrema offers riders the flexibility to choose between an adventure-focused or performance-driven cycling experience.

The Extrema's thoughtful design, featuring a round seat tube for dropper or suspension seatpost compatibility, ensures adaptability for navigating technical trails, while its aero frame tubes maintain efficiency for high-speed endeavors. The Extrema stands out as a versatile frame that seamlessly adapts to various riding styles and terrains, making it an ideal choice for those seeking a dynamic and responsive cycling experience.

Designed around 3T’s REALFAST aero shaping, the Extrema Italia uses actual tire dimensions—WAM (Width As Measured) and RAM (Radius As Measured)—to optimize airflow across the entire frame system. From the slim fork crown to the 75mm flared downtube and deep rear wheel cutout, every shape is tuned to reduce drag and improve performance across varied terrain. The result? A bike that moves fast, even when the trail turns rough.

The Extrema Italia is made to clear up to 57mm WAM tires with 700c wheels, giving it the ability to handle true off-road adventure without compromising race-day speed. 3Touring geometry increases stack and shortens reach for greater comfort and control, while a dropped chainstay design keeps the rear end stiff and responsive. The frame also features triple accessory mounts on the fork, internal routing through the 3T MORE Integrale system, and full compatibility with SRAM Transmission drivetrains.

Whether you're planning ultra-distance gravel events, multi-day bikepacking trips, or just want the fastest way across any terrain, the Extrema Italia frameset is the perfect place to start your build.
