Product Details
The 3T Strada Italia Ultegra Di2 2X12 ZIPP 303 road bike combines Italian-made performance with the reliability and precision of Shimano's top-tier electronic shifting. Built in Bergamo using 3T’s advanced filament winding and RTM carbon molding techniques, the frame offers a responsive, aero-optimized ride without sacrificing comfort. Geometry is tuned around 30–35mm WAM tires for exceptional speed, grip, and road-smoothing capability.
Designed for real-world aerodynamics, the Strada Italia’s tube shapes are tested at 20–30mph—even with bottles onboard—to deliver efficiency in everyday conditions. The Shimano Ultegra Di2 2x12 groupset ensures smooth, instant gear changes across a versatile range. Paired with Zipp 303 Firecrest wheels, this build delivers aerodynamic gains, dependable handling, and lightweight performance. Internal cable routing via the 3T MORE system completes a streamlined, travel-friendly cockpit setup.
