When speed is your obsession, this is your bike. You train, you put in the work, and this aero machine does the rest. Built to give you an edge when it really counts—on the attack, in the sprint, going all out—it delivers energy-saving efficiency and race-winning aero performance.
Developed and proven by the fastest sprinters on the CCC Team WorldTour squad, the 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 optimised 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 callipers and thru-axles for optimal wheel stiffness and braking performance. For pro-level road performance and the ultimate aero advantage, the Propel Advanced SL Disc puts you ahead of the pack.
AeroSystem Shaping, a result of CFD analysis and dynamic wind-tunnel testing, optimises aerodynamic performance at every yaw angle. The truncated ellipse airfoil tube shapes and Contact SLR Aero cockpit produce the best overall aero performance.
Integrated disc brakes deliver powerful stopping power and modulation for added control in all conditions and weather. Thru-axles boost stiffness and improve overall handling. And an integrated WheelSystem with a 65mm rear rim and 42mm front rim optimises aerodynamics and control.
Advanced SL-grade composite frameset features Giant’s highest performance materials and manufacturing processes for optimised stiffness and the lowest weight in its category.

Weight: The most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
