The Giant TCR Advanced Pro 1 Di2 is a high-performance road machine that serves as the perfect intersection of lightweight climbing ability and modern electronic precision. For 2026, this 10th-generation TCR has been re-engineered with a focus on "System Integration," featuring a frameset that is stiffer and more aerodynamic than its predecessor while remaining a leader in the stiffness-to-weight category. Built from Advanced-grade composite using cutting-edge manufacturing techniques to minimize structural waste, the TCR Advanced Pro 1 is designed to be a "total race bike" that excels in every scenario, from steep alpine passes to fast-paced criteriums.
This model features the OverDrive Aero system, marking the TCR's shift to a fully integrated cockpit. By routing the hydraulic hoses internally through the Contact SL AeroLight handlebar and stem, Giant has reduced drag while maintaining a clean, professional aesthetic. The bike is powered by the Shimano 105 Di2 12-speed groupset, providing the legendary reliability of Shimano’s electronic shifting at a more accessible level. Rolling on the all-new Giant SLR 1 40 Carbon wheels, the TCR Advanced Pro 1 offers an exceptionally responsive ride quality that reacts instantly to every pedal stroke.

Key Technologies
Advanced Composite: High-performance grade raw carbon material is used to produce a frame with a superior stiffness-to-weight ratio for explosive acceleration.
OverDrive Aero: A D-shaped steerer tube and integrated spacers provide an aerodynamic, internal cable routing system that is easier to service and adjust.
Variant Seatpost: Proprietary seatpost design balances lightweight and superior ride quality for a smooth, high-performance feel.
Hookless Rim Design: Enhances the rim's durability and allows for a wider inner rim width, improving tire shape and side-wall support for better cornering grip.
