Through CFD (Computational Fluid Dynamics) and wind-tunnel data, engineers optimize each tube shape to deliver superior aerodynamic performance.
Advanced Pro 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.
This full-composite, lightweight and aerodynamic seatpost is engineered specifically for performance road riding.
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 legs are constructed entirely from Giant’s Advanced SL-grade composite for the lightest weight and superior handling.
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.
New Cable Routing
Frame features all-new cable porting for sleek, non-cluttered appearance and easier adjustability.
Aero Bottle Cages
Custom-engineered down tube and seat tube-specific water bottle cages help minimize overall aerodynamic drag.
