Defy
Advanced SL 1
$9,499 RRP
WARNING: This product contains a button/coin battery and is hazardous. Keep batteries away from children.Go long. Go fast. Superlight and silky smooth, the flagship series of the new Defy range is back to reclaim its title as the pinnacle of endurance road. It’s the perfect choice for the sportive or gran fondo that’s circled on your calendar.
Key Performance Factors
Functional simplicity
Free of cumbersome gimmickry, the frameset is one of the lightest in its category. With a perfect balance of high-performance reactivity and all-day comfort, it offers a “less is more” experience for modern endurance road riding.
Engineered compliance
Advanced SL-grade composite frame and fork are specifically engineered for endurance road riding, delivering a smooth and efficient ride quality that minimises fatigue on long rides. The new D-Fuse components work together to further absorb road shocks and vibrations.
Total control
A new Contact D-Fuse handlebar features ergonomic shaping and an 8-degree flare for comfort and control on all-day rides. Wide, hookless carbon rims (22.4mm inner width) are optimised for high-volume tubeless tyres (up to 38mm), and a 36mm rim depth offers stable, predictable handling in crosswinds.
Ultralight Carbon Endurance Road Bike
With greater lateral stiffness and a superlight frame weight of 785g, this is the most efficient Defy ever. The composite frame layup targets smooth-riding performance for long, hard rides. The new D-Fuse SLR seatpost is now lighter and engineered with 40 percent added compliance. The Contact SLR D-Fuse handlebar, also new, features similar D-shaped tubing as the seatpost to absorb shocks and vibrations, plus an 8-degree flare for improved ergonomics and control. Component highlights include the new Contact SLR AeroLight stem with integrated cable routing. A CADEX 36 WheelSystem with superlight hookless carbon rims delivers snappy yet stable handling and superior tubeless tire performance.

Advanced SL Composite
2
OverDrive Aero
The D-shaped fork steerer tube and corresponding spacers provide an extremely aerodynamic, easier to service system of internally routed brake and derailleur cables.
3
D-Fuse SLR Seatpost
Proprietary seatpost features a D-shaped composite shaft to better absorb road vibrations without the need for mechanical devices or special inserts. Optimized carbon layup helps increase overall compliance by 40% over previous generation.
4
D-Fuse SLR Handlebar
Lightweight carbon handlebar with D-shaped tubing combines road-smoothing comfort (40% more compliant than the previous generation) with greater pulling (upward) stiffness for better efficiency while sprinting and climbing.
5
PowerCore
A massively oversized bottom bracket area features a fully integrated 86mm wide design. Asymmetric chainstays provide additional stiffness on the driveside and increased stability on the non-driveside.
6
Tubeless WheelSystem
Engineered with proprietary Dynamic Balanced Lacing technology, this tubeless ready composite WheelSystem delivers superior efficiency, pinpoint control and comfort.
7
Internal Cable Routing
Frame/handlebar/stem feature unique cable porting for sleek, non-cluttered appearance and performance.
8
Disc-Brake Integration
The frame and fork are engineered specifically for flat-mount disc-brakes, including front and rear 12mm thru-axles for reliable braking performance in all weather and road conditions.
9
Contact SLR Aerolight Stem
Composite integrated stem with semi-internal cable routing improves aero performance and aesthetics with wind tunnel-inspired design.
Techs & Features
Advanced Composite Technology
Giant’s High Performance Grade raw carbon material is used to produce this custom frame material in our own composite factory with a high stiffness-to-weight ratio. The front triangle of these framesets is assembled and moulded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction.
D-Fuse Technology
The D-Fuse seatpost and handlebar were designed to function as a system, absorbing road shocks and vibrations so you can ride further, faster.
PowerCore
A massively oversized bottom-bracket/chainstay area features a fully integrated, 86-millimetre wide bottom-bracket design (92-millimetre wide for off-road bikes). Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
Compact Road Design
Introduced by Giant with the professional Team ONCE in the 1990s, Compact Road revolutionized the look and feel of high-performance road bikes forever. A downward sloping toptube (from the headtube to the seattube) creates smaller front and rear triangles for a lighter, stiffer bike. It also makes it easier for riders of all sizes to have a perfect fit.
OverDrive Aero
Found inside the head tube of the Defy, Propel and TCR ranges, the D-shaped fork steerer tube and corresponding spacers provide an extremely aerodynamic, easier to service system of internally routed brake and derailleur cables.
