The Giant Defy Advanced SL 0 redefines what an endurance road bike should be, ultra-light, smooth-riding, and built for speed and comfort on the longest rides. Designed for sportives, Gran Fondos, and all-day adventures, this flagship model delivers exceptional performance without unnecessary complexity. Whether you're chasing distance, speed, or both, the Defy Advanced SL 0 is your ultimate endurance companion.
Featherweight Simplicity
Built with Advanced SL-grade carbon fibre, the Defy SL 0 is one of the lightest frames in its class. It strikes the perfect balance between stiffness, efficiency, and long-distance comfort, ideal for riders who want responsive handling without sacrificing ride quality.
Endurance-Specific Compliance
The frame and fork are specifically engineered to minimise fatigue on long rides. Integrated D-Fuse technology, in both the seatpost and handlebar, absorbs road vibrations and shocks, keeping you comfortable and in control over rough terrain and long distances.
Total Handling Control
The new Contact D-Fuse handlebar features ergonomic shaping and an 8-degree flare for improved control and comfort. Paired with hookless carbon wheels (22.4mm internal width) and support for high-volume tubeless tyres up to 38mm, this setup ensures predictable handling, even in crosswinds, thanks to its optimised 36mm rim depth.
Advanced SL-Grade Composite
Crafted from Professional-Grade carbon fibre, this frame offers unmatched stiffness-to-weight ratio. Used by Giant’s professional athletes, it’s designed for elite performance in road racing and endurance challenges alike.
Compact Road Design
Giant’s revolutionary Compact Road geometry, originally developed for the pro peloton, lowers the toptube and shortens the rear triangle for better power transfer, reduced weight, and a fit optimized for all rider sizes.
OverDrive Aero Integration
The internally routed OverDrive Aero system keeps brake and gear cables cleanly hidden inside the head tube via a D-shaped steerer. This setup not only improves aerodynamics but also simplifies serviceability.
PowerCore Bottom Bracket
An oversized bottom-bracket and chainstay area ensures uncompromising pedaling efficiency. The asymmetric chainstay design enhances stiffness on the drivetrain side and provides better balance and stability on the non-driveside.
Ideal For:
- Endurance road cyclists
- Gran Fondo and sportive riders
- Cyclists seeking long-distance comfort with lightweight performance
- Road riders who prioritise smooth handling, speed, and responsive geometry
If you're looking for one of the best high-performance endurance bikes available, the Giant Defy Advanced SL 0 is built to exceed expectations. With its advanced compliance system, race-ready carbon frame, and confidence-inspiring control, it’s engineered to keep you fast, smooth, and strong from mile one to mile one hundred and beyond.
