Giant Defy 3 (2015)
A light and lively aluminum feel, with engineered compliance to keep you going strong.
Brought to you by the world’s leading aluminum frame engineers, Defy redefines the performance possibilities of an aluminum road bike. Born in Giant’s own in-house aluminum forging facility and engineered with FluidForm ALUXX SL aluminum tubes, Defy blends comfort and control. Frame technologies include the OverDrive steerer tube for stiffness and sharp steering, the D-Fuse seatpost for vibration damping, and a PowerCore oversized bottom bracket area for stiff, efficient power transfer.
