Through CFD (Computational Fluid Dynamics) and wind-tunnel data, engineers optimize each tube shape to deliver superior aerodynamic performance.
Maximize your watts during sprints, breakaways and solo attacks. This aero road machine is reengineered to give you a real advantage against the wind. Because small gains lead to big wins.
Key Performance Factors
Integrated aerodynamics
AeroSystem Shaping, a result of CFD analysis and dynamic wind-tunnel testing, optimizes aerodynamic performance at every yaw angle. The truncated ellipse airfoil tube shapes and all-new Contact SL Aero cockpit produce superior aero performance.
Race-winning efficiency
Advanced-grade composite frame and full composite fork deliver optimal stiffness and weight savings. The result is an even greater stiffness-to-weight advantage.
Easier adjustability
All-new cable routing through the handlebar and frame makes it quicker and easier to adjust or change cockpit components and fine-tune performance and riding position.
Highlights of the Propel Advanced Aero Bike
Engineered with AeroSystem Shaping technology and Advanced-grade composite material, the all-new Propel Advanced combines proven aero performance and one of the lightest framesets in its category. New cable routing through the stem and head tube makes it quick and easy to adjust and dial in rider positioning. The lightweight, easily adjustable Vector composite seatpost further minimizes drag.

Aerosystem Shaping
Advanced Composite
High-performance grade raw carbon material is used to produce this custom material in our own composite factory with a high stiffness-to-weight ratio.
Aero Tubeless WheelSystem
Engineered with proprietary Dynamic Balanced Lacing technology, this composite aero WheelSystem and tubeless tires deliver superior efficiency, pinpoint control and superior aerodynamics.
OverDrive Aero
Found inside the head tube of the all-new Propel range, the D-shaped fork steerer tube and corresponding spacers provide an extremely aerodynamic, easier to service system of internally routed brake and derailleur cables.
Full Composite Fork
D-shaped steerer tube and fork legs are constructed entirely from Giant’s Advanced-grade composite for light weight and superior handling.
PowerCore
A massively oversized bottom bracket area features a fully integrated 86.5mm wide design. Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
Vector Seatpost
This full-composite, lightweight and aerodynamic seatpost is engineered specifically for performance road riding.
New Cable Routing
Frame and handlebar feature unique cable porting for sleek, non-cluttered appearance and easier adjustability.
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 Handlebar/Stem
Aero handlebar and stem are designed to reduce overall drag while minimizing weight.
Aero Bottle Cages
Custom-engineered down tube and seat tube-specific water bottle cages help minimize overall aerodynamic drag.
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.
AeroSystem Shaping Technology
Through CFD (Computational Fluid Dynamics) and wind-tunnel data, engineers optimize each tube shape to deliver superior aerodynamic performance.
Tubeless System
Fewer flat tires. Greater traction. Less rolling resistance and a smoother, faster ride. Giant’s Tubeless System makes it easier than ever to experience all these benefits.
OverDrive Aero
Found inside the head tube of the all-new Propel range, the D-shaped fork steerer tube and corresponding spacers provide an extremely aerodynamic, easier to service system of internally routed brake and derailleur cables.
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.
Vector Seatpost
This full-composite, lightweight and highly aerodynamic seatpost is engineered specifically for performance road riding.
RideSense Ready
This frame comes prepared to accept the Giant RideSense sensor and accompanying hardware.

- WeightThe most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
