Propel Advanced 1
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.
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.
Advanced-grade composite frame and fork deliver optimal stiffness and weight savings. The result is an even greater stiffness-to-weight advantage.
Giant’s 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.
Through CFD (Computational Fluid Dynamics) and wind-tunnel data, engineers optimize each tube shape to deliver superior aerodynamic performance.
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.
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.
