If 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 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 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.
