WARNING: This product contains a button/coin battery and is hazardous. Keep batteries away from children.From gran fondos to solo rides, this lightweight composite road bike features endurance geometry and built-in compliance. Smooth and fast, all day long.
Key Performance Factors
Engineered compliance
Advanced Composite frame is specifically engineered for endurance road riding, delivering a smooth ride quality and less fatigue on long rides. The D-Fuse seatpost and handlebar absorb road shocks and vibrations.
Total control
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 rough roads.
Versatility
Endurance road geometry, added tyre clearance (up to 35mm) and disc-brake integration allow you to tackle a variety of roads and conditions, from smooth pavement to rugged backroads and mountain passes.
Highlights
Defy Advanced Pro features a host of innovative technologies including a D-Fuse composite seatpost and Contact SLR D-Fuse composite handlebar. These components add compliance and reduce road shocks and vibrations. The Advanced-grade composite frame is also integrated for disc brakes, with flat-mount disc brake tabs and 12mm front and rear thru-axles, plus clearance for high-volume tires up to 35mm. The oversized and tapered OverDrive 2 steerer tube boosts cornering precision, while the MegaDrive downtube and PowerCore bottom bracket deliver precise handling and class-leading pedaling efficiency.

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.
OverDrive 2
The most advanced steerer tube technology in today’s Giant bikes. Designed to offer unprecedented front-end steering performance, the system’s oversized headset bearings (1 1/2” lower, 1 1/4” upper) and tapered steerer tube work in harmony to provide supreme steering stiffness.
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.
Tubeless System
Fewer flat tyres. Greater traction. Less rolling resistance and a smoother, faster ride. Giant’s Tubeless System makes it easier than ever to experience all these benefits.
RideSense Ready
This frame comes prepared to accept the Giant RideSense sensor and accompanying hardware.
