Giant Defy Advanced 1 Road Bike 2025

Featuring no superfluous amenities, the frameset is one of the lightest in its class. Its ideal blend of quick response and extended comfort complements a "less is more" approach to today's endurance road riding.
Advanced-grade composite frames and forks are designed for extended road cycling, providing a comfortable and energy-efficient ride that mitigates fatigue on extended rides. The latest D-Fuse components combine to further reduce impact from road bumps and vibrations.
Ergonomic shaping and a 8° flare on the Contact D-Fuse handlebar provide comfort and control during extended rides. The hookless carbon rims with an inner width of 22.4mm are optimised for tubeless tyres up to 38mm, with a 36mm depth for a steady, predictable ride in gusty winds.
