2025 Giant TCR Advanced Pro 1 Di2 Road Bike

2025 GIANT TCR ADVANCED PRO 1 DI2 ROAD BIKE

KEY PERFORMANCE FACTORS

SYSTEM OPTIMIZATION
The frameset, wheels, cockpit and other parts are engineered, developed and tested together to perform as a system. The all-new OverDrive Aero steerer tube technology is combined with a Contact SL AeroLight stem and Contact SL handlebar to incorporate internal cable routing that integrates the top cap, cables and spacers in a more aerodynamic, user-friendly setup.

WINNING EFFICIENCY
Featuring a greater stiffness-to-weight ratio than the previous generation, along with new aero tube shaping and a lighter overall weight, this uncompromising race bike delivers explosive acceleration and unyielding pedaling stiffness. The result is race-winning performance in the moments that count.

INTEGRATED AERODYNAMICS
All tube shapes are engineered and developed using Computational Fluid Dynamics (CFD) modeling and wind-tunnel testing. From the truncated ellipse shape of frameset tubing to a new cockpit design and component integration, it all adds up to a more streamlined profile that improves overall aero performance compared to the previous generation.

Weight
The most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
