Giant DEFY ADVANCED SL - Carbon Road Bike - 2025 - black lava

Go all out. 

Superlight yet comfortable, the flagship series of the new Defy range is back to reclaim its title as the top model among endurance road bikes. It's the perfect choice for the race or Gran Fondo you've set your sights on.

Highlights Giant DEFY ADVANCED SL - Carbon Road Bike

• Lightning-fast, electronic shifting over 2x12 gears with the SRAM Red eTap AXS groupset
• Advanced SL Composite – The frame is made from the highest grade carbon fiber. Thanks to carbon nanotube (CNT) technology, the frame has 14 times greater impact resistance than frames without CNT and is up to 100 g lighter.
• D-Fuse technology - The seatpost and handlebars with D-Fuse technology are designed to work as a system to absorb shocks and vibrations from the road, allowing you to ride further and faster.
• Contact SLR D-Fuse Handlebar - The lightweight carbon handlebar with D-shaped tubes combines road comfort with higher tensile stiffness (upward) for greater efficiency when sprinting and climbing.
• Contact SLR Aerolight Carbon Stem - The integrated carbon stem with internal cable routing improves aero performance.
• Compact Road Design - A sloping top tube creates smaller front and rear triangles for a lighter, stiffer bicycle. It makes it easier for riders of all sizes to find the perfect fit.
• High-end carbon frame and fork
• Wide, hookless carbon rims (22.4 mm internal width) are optimized for high-volume tubeless tires (up to 38 mm), and a rim depth of 36 mm provides stable, reliable handling in crosswinds.
• The frame/handlebars/stem feature integrated cable routing for a sleek, clean look and performance.

DEFY ADVANCED SL technologies

Advanced SL Composite Technology - This highest grade carbon fiber is used to create an exclusive composite frame material that is woven and processed in Giant's own factory. Carbon nanotube (CNT) technology involves adding a microscopic polymer to GIANT's special resin mixture. These CNT particles act as miniature support pillars, strengthening the composite layers. CNT-treated frames are 14 times more impact-resistant than frames without CNT and are up to 100 g lighter. 

Compact Road Design - The Compact Road Design was introduced in the 1990s by GIANT with the professional ONCE team and revolutionized the look of high-performance road bikes forever. A downward-sloping top tube creates smaller front and rear triangles for a lighter, stiffer bicycle. It makes it easier for riders of all sizes to find the perfect fit.

OverDrive Aero - The D-shaped steerer tube provides an extremely aerodynamic, easier-to-maintain system of internally routed brake and shift cables.

D-Fuse Seatpost - The proprietary D-shaped composite seatpost acts as a shock absorber, dampening vibrations for a smooth, comfortable ride.
