2019 Defy Advanced Pro

DEFY LIMITS
This all-new high-performance frameset is handcrafted with Giant’s Advanced composite and specifically engineered for endurance road riding. With the perfect blend of stiffness and compliance, it delivers a smooth, fast ride quality for your longest, hardest rides. Its innovative technologies include a D-Fuse composite seatpost and Contact SLR D-Fuse composite handlebar, specially shaped cockpit components that work as a system to add compliance and reduce road shocks and vibrations. The frame is also integrated for disc brakes, with flat mounts and 12mm front and rear thru-axles, plus clearance for high-volume tires up to 32c. 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.
From bare thread to finished frame, every Giant composite bicycle is designed, engineered and hand-built in our own factory. Using state-of-the art materials and manufacturing techniques, Advanced-Grade Composite framesets offer outstanding weight, stiffness and compliance characteristics.
Giant’s most advanced steerer tube technology offers unprecedented steering precision. Oversized headset bearings (1 1/2” lower, 1 1/4" upper) and a tapered steerer tube produce
superior front-end 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, 86-millimeter wide bottom-bracket design. Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
Giant’s chainstay integrated, wireless data transmitter. The removable transmitter sends wheel speed and cadence information directly to any Bluetooth compatible computer.
Engineered with proprietary Dynamic Balanced Lacing technology, Giant’s all-new SLR-1 Disc composite WheelSystem delivers superior efficiency, pinpoint control and comfort. The
wheels are integrated with Giant Gavia AC 1 28c tubeless tires for added rolling efficiency and a reduced risk of flats.
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.
Composite integrated stem improves aero performance and aesthetics with wind tunnel inspired design and internal cable routing.
Integrated, dual-sided power meter measures power output and delivers accurate data to help you track, analyze and improve performance. With multi-axis left and right crank arm sensors, it pairs with the Giant NeosTrack GPS computer to display vital information including power (watts), pedal balance, force angle and cadence. It’s also compatible with other popular ANT+ head units. (*Available on Defy Advanced Pro 0 model)
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 molded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction.
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.
Specific composite layup and tube shaping, including ultra-thin and flattened seatstays, a low seatstay/seattube junction, and thin, slightly curved fork legs combine for a balanced, compliant ride quality and reduced rider fatigue.
The D-Fuse seatpost and handlebar were designed to function as a system, absorbing road shocks and vibrations so you can ride farther, faster.
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.
Tracking your power output and training data has never been easier. The all-new Power Pro system from Giant delivers accurate information with an integrated system that’s precise, reliable and simple to set up. The most effective training is smart training, so start training with power.
Giant’s chainstay integrated, wireless data transmitter. The removable transmitter sends wheel speed and cadence information directly to any ANT+ compatible computer.
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.
