The Giant Defy Advanced 0 focuses on functional simplicity, delivering a clean, refined endurance road bike built to perform over long hours in the saddle. The Advanced-grade composite frame is one of the lightest in its class, carefully engineered to balance responsiveness with comfort rather than chasing outright stiffness.
Endurance geometry places you in a stable, efficient riding position that reduces fatigue on long rides, steep climbs and rougher road surfaces. The full carbon fork and oversized OverDrive steerer improve front-end precision, giving confident handling on descents and through fast corners.
Comfort is a defining feature of the Defy. Giant’s D-Fuse system, used in both the composite seatpost and Contact D-Fuse handlebar, is designed to flex slightly under load. This helps absorb road buzz and repeated impacts from broken tarmac or cobbles, keeping the ride smooth without feeling dull.
Shimano 105 Di2 electronic shifting delivers fast, consistent gear changes with minimal effort. The 2x12 setup, paired with an 11–36T cassette, provides a wide gear range well suited to long climbs, rolling terrain and steady cruising.
The Giant SLR 2 40 carbon wheelset is optimised for endurance riding, offering a balance of low weight and stability. Wide rims are matched with 32c tubeless Giant Gavia Fondo tyres, improving comfort, grip and puncture resistance while maintaining predictable road handling.
With clean design, reliable electronic shifting and carefully tuned compliance, the Defy Advanced 0 is built for riders who want to ride further, stay comfortable and enjoy consistent performance on every mile.
