Through CFD (Computational Fluid Dynamics) and wind-tunnel data, engineers optimize each tube shape to deliver superior aerodynamic performance.
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.
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.
Key Performance Factors
Integrated aerodynamics
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 SL Aero cockpit help produce the best overall aero performance.
Total control
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 shallower 42mm front rim optimises aerodynamics and control.
Unrivaled efficiency
Advanced-grade composite frameset features high-performance materials and modern manufacturing processes for optimised stiffness and the lowest weight in its category.
Aerosystem Shaping Technology
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.
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.
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.
Vector Seatpost
This full-composite, lightweight and highly aerodynamic seatpost is engineered specifically for performance road riding.
Internal Cable Routing
Frame/handlebar/stem feature unique cable porting for sleek, non-cluttered appearance and performance.
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.
Aero Bar and Stem
Contact SLR aero composite handlebar and Contact SL Aero alloy stem are designed to reduce overall drag while minimizing weight.
