Through CFD (Computational Fluid Dynamics) and wind-tunnel data, engineers optimize each tube shape to deliver superior aerodynamic performance.
Propel Advanced Disc
On the attack, in a sprint, or cornering at speed. Efficiency meets total control in this wind-slicing missile. Engineered with AeroSystem Shaping technology, an integrated WheelSystem, and disc brakes that are both powerful and aerodynamic, it gets up to speed and stays there with minimal resistance.

Highlights
This aero road bike minimizes drag so you can accelerate and sprint faster. Engineered with AeroSystem Shaping technology and Advanced-grade composite material, it delivers proven aero performance and one of the lightest frames in its category. The Propel Advanced Disc also comes with an integrated WheelSystem, flat-mount disc-brake calipers and thru-axles for added wheel stiffness and streamlined performance. The lightweight, easily adjustable Vector composite seatpost further minimizes drag. It all adds up to a race-ready machine that leaves the competition behind.

Aerosystem Shaping Technology
2
Advanced Composite Frame
High Performance Grade raw carbon fiber and Giant’s proprietary resin formula is used to produce custom composite material in our own composite factory that is extremely lightweight, stiff and compliant.
3
OverDrive
Giant’s original oversized fork steerer tube technology. Designed to provide precise front-end steering performance, the system’s oversized headset bearings (1 1/4” lower and 1 1/8” upper) and tapered steerer tube work in conjunction to provide optimal steering stiffness.
4
PowerCore
A massively oversized bottom-bracket/chainstay area features a fully integrated, 86-millimeter wide bottom-bracket design. Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
5
Vector Seatpost
This full-composite, lightweight and highly aerodynamic seatpost is engineered specifically for performance road riding.
6
Internal Cable Routing
Frame/handlebar/stem feature unique cable porting for sleek, non-cluttered appearance and performance.
7
Disc-Brake Integration
The frame and fork are engineered specifically for flat-mount disc-brakes, including front and rear 12mm thru-axles for reliable braking performance in all weather and road conditions.
8
Aero Bar and Stem
Contact SLR aero composite handlebar and Contact SL Aero alloy stem are designed to reduce overall drag while minimizing weight.
Techs & Features
Advanced Composite Technology
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.

Giant’s original oversized fork steerer tube technology. Designed to provide precise front-end steering performance, the system’s oversized headset bearings (1 1/4” lower and 1 1/8” upper for road, 1 1/2” lower and 1 1/8” upper for mountain) and tapered steerer tube work in conjunction to provide optimal steering stiffness.
PowerCore
A massively oversized bottom-bracket/chainstay area features a fully integrated, 86-millimeter wide bottom-bracket design (92-millimeter wide for off-road bikes). Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
