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)
