Developed and proven by the fastest sprinters on the CCC Team WorldTour squad, the 2021 Giant Propel Advanced SL 1 Disc Road Bike 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.
The 2021 Giant Propel Advanced SL 1 Disc Road Bike’s 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.
KEY PERFORMANCE FACTORS
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.
