Key Performance Factors
Integrated aerodynamics
Easier adjustability
Race-winning efficiency
Advanced SL Composite Technology
Professional Grade raw carbon fiber is woven in our composite factory to produce our lightest stiffest and highest quality frames. This is the technology used by Giant’s pro racers in almost every cycling discipline.
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.
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.
Integrated Seatpost
Designed as a key performance factor in the overall frameset the integrated seatpost saves up to 40 grams compared to standard composite posts while improving aerodynamics and adding road-smoothing compliance.
