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.
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 tire 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.

Advanced Composite
OverDrive 2
Giant’s most advanced steerer tube technology offers unprecedented steering precision. Oversized headset bearings (1 1/2” lower, 1 1/8” upper) and a tapered steerer tube produce superior front-end stiffness.
D-Fuse Technology
Proprietary D-shaped composite seatpost and handlebar work together to dampen vibrations and absorb road shock, resulting in a smoother, more compliant ride quality.
PowerCore
A massively oversized bottom-bracket/chainstay area features a fully integrated, 86mm wide bottom-bracket design. Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
Giant WheelSystem
Engineered with proprietary Dynamic Balanced Lacing technology, this tubeless ready composite WheelSystem delivers superior efficiency, pinpoint control and comfort.
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.
INTERNAL CABLE ROUTING
Frame/handlebar/stem feature unique cable porting for sleek, non-cluttered appearance and performance.
CONTACT SL STEALTH STEM
Composite integrated stem improves aero performance and aesthetics with wind tunnel-inspired design and internal cable routing.

- GreutateCat cantareste bicicleta? Este o intrebare uzuala si indreptatita. Adevarul este ca nu exista un standard al industriei care sa reglementeze aceasta masurare, si asta duce la multe confuzii. Variatiile au drept cauza marimile si materialul cadrului, finisajele si echiparile. Cum tendinta este spre o greutate mai redusa, fiecare astfel de detaliu conteaza. GIANT considera ca singura cale prin care poti fi sigur 100% de greutatea unei biciclete este de a solicita cantarirea ei la magazin.
