An Aero Rocketship

Now even faster, the 2025 Giant Propel Advanced Pro Frameset is built for speed when it matters most. This reengineered frameset is even more adept at slicing through wind, and it’s also lighter than the previous generation. The result? Race-winning efficiency that’s hard to beat.

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 Aero

Found inside the head tube of the Defy, Propel and TCR ranges, the D-shaped fork steerer tube and corresponding spacers provide an extremely aerodynamic, easier to service system of internally routed brake and derailleur cables.

Features:

• Frame – Advanced-Grade Composite, 12x142mm thru-axle, disc
• Fork – Advanced SL-Grade Composite, full-composite OverDrive Aero steerer, 12x100mm thru-axle, disc, with headset
• Seatpost – Giant Vector, composite, -5/+15mm offset
• Extras – computer mount, bottle cages, 32mm max tire size
