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.
