Giant Defy Advanced 1 Road Bike

Giant Defy Advanced 1 Road Bike

Choose the longer route. Climb higher mountains. This smooth-riding endurance road bike is made for long-distance rides on all types of roads.


Key Performance Factors

Engineered compliance

Advanced Composite frame is engineered for endurance road riding. The D-Fuse seatpost and handlebar absorb road shocks and vibrations, and its smooth ride quality means you’ll feel less fatigue on long rides.

Total control

Seamless disc brake integration including flat mounts and 12mm front and rear thru-axles produces more consistent braking power for better control, even in wet weather and on rough roads.


Endurance road geometry, plenty of tire clearance (up to 35mm), and disc-brake integration allow you to tackle a variety of roads and conditions, from smooth pavement to rugged mountain passes.
