THE FUTURE OF AERO ROAD. LIGHTWEIGHT, STIFF AND NEARLY INVISIBLE TO THE WIND, PLUS THE ADDED CONTROL OF Disc BRAKES.
Meticulously developed for best-in-class aero road performance, this razor-sharp road racer offers a true advantage for sprinting and solo riding. And new this year, it also incorporates the superior control of disc brakes. The frame is handcrafted using Advanced-grade composite material to produce a bike that’s lightweight and stiff, with a sharp, responsive ride quality. Its disc brakes are completely integrated within the frame using flat-mount calipers and thru-axles designed to optimize the technology. From sprints to solo attacks, cornering and descents, the new Propel Advanced Pro Disc helps you slice through the wind and gain an advantage on the competition.
Extensive CFD analysis and dynamic wind-tunnel testing were used to optimize every frame tube and angle in a process called AeroSystem Shaping technology. The frame is handcrafted using Advanced-grade composite material to produce a bike that’s lightweight and stiff, with a sharp, responsive ride quality. Disc brakes are integrated with the frame using flat-mount calipers, thru-axles and an asymmetric fork to maximize aerodynamic performance. From sprints to solo attacks, cornering and descents, the new Propel Advanced Pro Disc helps you slice through the wind and gain an advantage on the competition. Here's a look at its key technologies/

Giant’s High Performance Grade raw carbon material is used to produce this custom frame material in our own composite factory with a high stiffness-to-weight ratio. The front triangle of these framesets is assembled and molded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction.
Through CFD (Computational Fluid Dynamics) and wind-tunnel data, engineers optimize each tube shape to deliver superior aerodynamic performance.
The most advanced steerer tube technology in today’s Giant bikes. Designed to offer unprecedented front-end steering performance, the system’s oversized headset bearings (1 1/2” lower, 1 1/4” upper) and tapered steerer tube work in harmony to provide supreme steering stiffness.
Giant’s chainstay integrated, wireless data transmitter. The removable transmitter sends wheel speed and cadence information directly to any ANT+ compatible computer.
This full-composite, lightweight and highly aerodynamic seatpost is engineered specifically for performance road riding.
