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.

Defy Advanced Pro
Defy Limits
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
Tecnologia ingegnerizzata
Il telaio in carbonio Advanced è specificamente progettato per la guida su strada endurance, offrendoti una qualità di guida fluida e meno faticosa nei lunghi viaggi. Il reggisella e il manubrio D-Fuse assorbono efficacemente gli urti e le vibrazioni della strada.
Controllo totale
L'integrazione perfetta del freno a disco, che includono flat mounts e perni passanti anteriori e posteriori da 12mm, produce una migliore potenza di frenata per un controllo migliore, anche in caso di pioggia o strade sconnesse.
Versatilità
La geometria Endurance, il maggiore spazio per gli pneumatici (fino a 35mm) e l'integrazione del freno a disco consentono di affrontare una varietà di superfici e condizioni, dall'asfalto liscio ai passaggi di montagna accidentati.
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.
