The Defy is crafted for extended journeys—scaling higher peaks, riding harder, all with unwavering confidence and seamless control. It's about pushing boundaries, surpassing limits, and revelling in the ride. The latest Defy, now in its fifth generation, enhances the beloved qualities riders cherish—plentiful compliance and lightweight efficiency. It emerges lighter, smoother, and more efficient, making it the ideal partner for enduring sportives, ambitious gran fondos, or conquering challenging roads on an epic solo adventure.
The Giant Defy features their D-Fuse handlebar and seat post on select models. These components significantly improve the ride comfort on those rougher roads.
Giant's testing found that the flagship Defy Advanced SL provides up to 8.9 percent greater transmission stiffness than its top-of-the-line predecessor (2023 Defy Advanced Pro).
Increased frame stiffness means better power transmission, enabling the rider to reach and maintain higher speeds with less effort. The combination of lower weight and higher stiffness adds up to unrivaled overall efficiency.

The sizing chart is a great place to start when picking your next bike but everyone will fit a bike a bit differently. Your torso, arm, and leg lengths all play into what size of bike you may need. Plus, there's your own personal preference.
We always recommend swinging by the shop and taking the bike that you're looking for a spin to see how it feels. If you're unable to come by, looking at the geometry of your current bike and comparing it is a good place to start. If you have any further questions, our customer service team is there to help.
