3T Racemax Italia GRX Di2 2X12 Discus 45/40 CTi

The 3T RaceMax Italia GRX Di2 2x12 is a high-performance gravel bike that balances aerodynamics, speed, and the craftsmanship of a handmade Italian carbon frame. Built in Presezzo, Italy, this model reflects 3T’s engineering at its finest—where every layer, line, and cable path is optimized for speed, control, and versatility.

At the heart of the design is 3T’s REALFAST aero shaping, based on actual tire measurements—WAM (Width As Measured) and RAM (Radius As Measured). This makes the frame shaped for how tires perform in the real world, delivering low drag across a wide range of surfaces. It’s quick on the tarmac, efficient on fast gravel, and can clear tires up to 61mm wide (with 650b wheels), giving you serious flexibility for mixed-surface riding and racing.

This build features Shimano’s GRX Di2 2x12 electronic drivetrain, offering precise shifts and a broad gearing range for technical climbs and fast descents. A fully integrated 3T Aeroghiaia LTD carbon cockpit keeps the front end clean and aero, while the Discus 45/40 CTi carbon wheels offer fast rolling and confident handling. 3T’s MORE Integrale system routes cables internally without compromising fit or ease of service.

The RaceMax Italia GRX Di2 2x12 is made for riders who want a fast, refined gravel machine with the quality and soul of true Italian construction.
