Propel Advanced Pro (Dura Ace)

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

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 Contact SLR/SL Aero cockpit produce the best overall 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 frameset features high-performance materials and proprietary manufacturing processes. As a result, its lighter than the previous generation for an even greater stiffness-to-weight ratio.

Technologies

Advanced Composite Technology

Giants High Performance Grade raw carbon material is used to produce this custom frame material in our 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.

AeroSystem Shaping Technology

Through CFD (Computational Fluid Dynamics) and wind-tunnel data, engineers optimize each tube shape to deliver superior aerodynamic performance.

Tubeless System

Fewer flat tires. Greater traction. Less rolling resistance and a smoother, faster ride. Giants Tubeless System makes it easier than ever to experience all these benefits.

OverDrive 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.
