Propel Advanced Pro
Developed with pro sprinters and proven in the heat of the battle, the all-new Propel Advanced Pro combines the superior aerodynamic performance of the current Propel Disc range with the convenience of new and improved rim brake performance. Extensive CFD analysis and dynamic wind-tunnel testing was used to optimize every frame tube and angle in a process called AeroSystem Shaping technology. The frame is handcrafted using Advanced-grade composite material to produce a bike that is both lightweight and stiff, with a sharp, responsive ride quality. Purpose-built aero road technologies, including SpeedControl brakes, a Vector seatpost and new rim-brake technology put the new Propel Advanced Pro ahead of the pack.
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.
A massive rectangular downtube and oversized toptube work in unison to provide superior front end lateral and torsional steering precision. The precisely engineered, rectangular shaped downtube yields unprecedented steering and pedaling stiffness.
A massively oversized bottom-bracket/chainstay area features a fully integrated, 86-millimeter wide bottom-bracket design (92-millimeterwide for off-road bikes). Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
