This Giant Defy Advanced SL 1 2024 is available with our legendary Podium Point free accessory scheme.

The new Giant Defy is here. Designed around the needs of Sportive and Gran Fondo riders the Defy is a composite engineering masterpiece which combines true endurance comfort with a lively and responsive ride.

Free of cumbersome gimmickry, the frameset is one of the lightest in its category. With a perfect balance of high-performance reactivity and all-day comfort, it offers a "less is more" experience for modern endurance road riding.

Advanced SL-grade composite frame and fork are specifically engineered for endurance road riding, delivering a smooth and efficient ride quality that minimises fatigue on long rides. The new D-Fuse components work together to further absorb road shocks and vibrations.

A new Contact D-Fuse handlebar features ergonomic shaping and an 8-degree flare for comfort and control on all-day rides. Wide, hookless carbon rims (22.4mm inner width) are optimised for high-volume tubeless tyres (up to 38mm), and a 36mm rim depth offers stable, predictable handling in crosswinds.

With greater lateral stiffness and a superlight frame weight of 785g, this is the most efficient Defy ever. The composite frame layup targets smooth-riding performance for long, hard rides. The new D-Fuse SLR seatpost is now lighter and engineered with 40 percent added compliance. The Contact SLR D-Fuse handlebar, also new, features similar D-shaped tubing as the seatpost to absorb shocks and vibrations, plus an 8-degree flare for improved ergonomics and control. Component highlights include the new Contact SLR AeroLight stem with integrated cable routing. A Giant SLR1 composite 36 WheelSystem with lightweight hookless carbon rims which delivers fast yet stable handling and superior tubeless tyre performance.

Please note: This model features tubeless ready wheels and tyres which offer a superior ride and less rolling resistance than traditional innertubes. This system requires tyre sealant to function correctly and this will be fitted in our workshop prior to despatch. The nature of this sealant means that the tyre may not be fully sealed until it has been ridden a short distance and therefore the bicycle may arrive with reduced pressure in the tyres. Please check the bicycle's tyres are inflated to the recommended pressure before cycling.

Rider Height (ft)
Rider Height (m)

Sizing information is provided as a general guide only. This is based on the average rider riding the bicycle in the style for which it is intended. This takes no account of a rider's personal proportions, physique, flexibility and biomechanics. If your height places you on, or near, a bicycle size step then we recommend you consider both sizes. All bicycles offer a range of handlebar and saddle adjustment which will enable you to fine tune your riding position once the correct size has been established. If you are unsure on sizing, we strongly recommend you visit our store so we can assist you. Pedal On offers advice and information on sizing in good faith, the final decision and responsibility on which size to purchase is yours.
