Go longer, ride smoother, and push your endurance with confidence. The 2025 Giant Defy Advanced 2 is engineered for those who seek comfort and control on epic road rides—featuring a lightweight composite frame, endurance geometry, and road-smoothing technologies that keep you rolling strong, even on rough surfaces.

KEY PERFORMANCE FACTORS

Engineered for Endurance

The Advanced-grade composite frame is built for long-distance comfort and efficiency. With its endurance-focused geometry and integrated seat clamp, the Defy offers a smooth, fatigue-fighting ride—perfect for all-day efforts.

Smooth Ride Quality

Innovative D-Fuse technology in the seatpost and handlebar helps absorb road vibrations and shocks, keeping your ride smoother and reducing fatigue over time.

Control You Can Trust

Integrated disc brakes with 12mm thru-axles and generous tyre clearance (up to 38mm) deliver confident handling, powerful stopping, and added traction on rough roads or in changing weather.

TECHS & FEATURES

×

ADVANCED COMPOSITE TECHNOLOGY

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 moulded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction.

×

COMPACT ROAD DESIGN

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.

OVERDRIVE AERO

Found inside the head tube of the all-new Propel range, the D-shaped fork steerer tube and corresponding spacers provide an extremely aerodynamic, easier to service system of internally routed brake and derailleur cables.

×

TUBELESS SYSTEM

Fewer flat tyres. Greater traction. Less rolling resistance and a smoother, faster ride. Giant’s Tubeless System makes it easier than ever to experience all these benefits.
