Highlights
Engineered with AeroSystem Shaping technology and Advanced-grade composite material, the Propel Advanced Disc delivers proven aero performance and one of the lightest frames in its category. It 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.

AEROSYSTEM SHAPING
2
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.
3
Aero WheelSystem
Engineered with proprietary Dynamic Balanced Lacing technology, this composite aero WheelSystem delivers superior efficiency, pinpoint control and superior aerodynamics.
4
OVERDRIVE
Giant’s proven oversized fork steerer tube technology is 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.
5
POWERCORE
A massively oversized bottom-bracket/chainstay area features a fully integrated, 86mm wide bottom-bracket design. Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
6
VECTOR SEATPOST
This full-composite, lightweight and aerodynamic seatpost is engineered specifically for performance road riding.
7
INTERNAL CABLE ROUTING
Frame/handlebar/stem feature unique cable porting for sleek, non-cluttered appearance and performance.
8
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.
9
AERO HANDLEBAR/STEM
Aero handlebar and 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.
AeroSystem Shaping Technology
Through CFD (Computational Fluid Dynamics) and wind-tunnel data, engineers optimize each tube shape to deliver superior aerodynamic performance.
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 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.
Vector Seatpost
This full-composite, lightweight and highly aerodynamic seatpost is engineered specifically for performance road riding.
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.
