Through CFD (Computational Fluid Dynamics) and wind-tunnel data, engineers optimize each tube shape to deliver superior aerodynamic performance.
Launch your attack. Sprint for the win. This composite aero rocketship combines AeroSystem Shaping Technology with disc-brake integration. The result: control, efficiency, and race-winning speed.
Developed with pros including 2017 Tour de France points classification winner Michael Matthews, the new Propel Advanced SL Disc delivers ultimate speed through integrated aerodynamics. It’s engineered with Giant’s AeroSystem Shaping technology, which means every tube shape and angle is optimized for minimal drag. These tubes feature a “truncated ellipse” shape, which also result in a frame that is ultra-stiff and superlight. Disc-brake technology is integrated into the frameset with flat-mount calipers and thru-axles for optimal wheel stiffness and braking performance. For pro-level road performance and the ultimate aero advantage, the new Propel Advanced SL Disc puts you way ahead of the pack.
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 Aero cockpit help produce the best overall aero performance.
Integrated disc brakes deliver powerful stopping power and modulation for added control in variable weather. Thru-axles boost stiffness and improve overall handling and an integrated WheelSystem with a 65mm rear rim and 42mm front rim optimizes aerodynamics and control.
Advanced SL-grade composite frameset features Giant’s highest performance materials and manufacturing processes for optimized stiffness and the lowest weight in its category.
