Giant Propel Advanced Pro 0 Di2 2026 Bike

This aero rocketship is built for speed when it matters most. It's lighter than the previous generation and engineered to slice through wind. The result? Race-winning efficiency that puts you ahead of the pack.

Features

Integrated Aerodynamics

AeroSystem Shaping, a result of CFD analysis and dynamic wind-tunnel testing, optimizes aerodynamic performance at every yaw angle. The truncated ellipse airfoil tube shapes and all-new Contact SL Aero cockpit produce superior aero performance.

Easier Adjustability

All-new cable routing through the stem and head tube makes it quicker and easier to adjust or change cockpit components and fine-tune performance and riding position.

Race-Winning Efficiency

Advanced-grade composite frame and fork deliver optimal stiffness and weight savings. The result is an even greater stiffness-to-weight advantage.

Technologies

• Advanced Composite Technology: Giant's High Performance Grade raw carbon material is used to produce this custom frame material in Giant's own composite factory with a high stiffness-to-weight ratio. The front triangle of these framesets is assembled and molded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction.
• Aero System Shaping Technology: Through CFD (Computational Fluid Dynamics) and wind-tunnel data, engineers optimize each tube shape to deliver superior aerodynamic performance.
• Over Drive Aero: Found inside the head tube of the Defy, Propel and TCR ranges, the D-shaped fork steerer tube and corresponding spacers provide an extremely aerodynamic, easier to service system of internally routed brake and derailleur cables.
• Tubeless System: Fewer flat tires. Greater traction. Less rolling resistance and a smoother, faster ride. Giant's Tubeless System makes it easier than ever to experience all these benefits.
