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.
Compact Road Design
Introduced by Giant with the professional Team ONCE in the 1990s Compact Road revolutionized the look and feel of high-performance road bikes forever. A downward sloping toptube (from the headtube to the seattube) creates smaller front and rear triangles for a lighter stiffer bike. It also makes it easier for riders of all sizes to have a perfect fit.
D-Fuse Seatpost
The proprietary “D” shaped composite seatpost damps vibration, resulting in a smooth, compliant ride.
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.
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.
