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.

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.
