CHOOSE THE LONGER ROUTE. CLIMB HIGHER MOUNTAINS. THIS SMOOTH-RIDING ENDURANCE ROAD BIKE IS MADE FOR LONG-DISTANCE RIDES ON ALL TYPES OF ROADS.
KEY PERFORMANCE FACTORS
Advanced Composite frame is specifically engineered for endurance road riding, giving you a smooth ride quality and less fatigue on long rides. The D-Fuse seatpost and handlebar absorb road shocks and vibrations.
Seamless 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.
Endurance road geometry, added tire clearance (up to 35mm) and disc-brake integration allow you to tackle a variety of roads and conditions, from smooth pavement to rugged mountain passes.
Handcrafted with Advanced-grade composite material, the Defy Advanced is made with a specific carbon layup to give it an efficient, high-performance ride quality that helps you push new limits of endurance. The D-Fuse seatpost and handlebar system also help reduce road vibrations, adding to its smooth, compliant feel on the road. A tubeless Giant WheelSystem and tires boost speed and efficiency with a reduced risk of flats. And for added control, it features integrated disc brakes with flat-mount disc brake tabs and 12mm thru-axles.
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 is assembled and molded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction.
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.
Giant's proven oversized fork steerer tube technology. Designed to provide precise front-end steering performance, the system's oversized headset bearings (1 1/4" lower and 1 1/8" upper) and tapered steerer tube work in conjunction to provide optimal steering stiffness.
Proprietary D-shaped composite seatpost and handlebar work together to dampen vibrations and absorb road shock, resulting in a smoother, more compliant ride quality.
A massively oversized bottom-bracket/chainstay area features a fully integrated, 86mm wide bottom-bracket design. Asymmetric chainstays provide additional stiffness on the drive-side and stability on the non-drive-side.
INTERNAL CABLE ROUTING
Frame/handlebar/stem feature unique cable porting for sleek, non-cluttered appearance and performance.
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.
GIANT WHEEL SYSTEM
Engineered with proprietary Dynamic Balanced Lacing technology, this tubeless-ready composite WheelSystem delivers superior efficiency, pinpoint control, and comfort.
Fewer flat tires. Greater traction. Less rolling resistance and a smoother, faster ride. Giant's Tubeless System makes it easier than ever to experience all these benefits.
This frame comes prepared to accept the Giant RideSense sensor and accompanying hardware.
