Giant Defy Advanced SL 1 Road Bike in Dark Green

Season:2026

Brand:Giant

Code:9031019DS

Superlight and silky smooth, the Giant Defy Advanced SL 1 is back to reclaim its title as the pinnacle of endurance road performance.

If you've been asking yourself what Giant road bike to buy for sportives, gran fondos, or simply long days in the saddle, the answer starts here.

This Giant Advanced road bike sits at the top of the new Defy range, and it earns that position. It's one of the lightest bikes in its category, built for riders who want a machine that disappears beneath them and just lets them ride. The striking Giant Defy green colourway makes it as easy to spot on the road as it is to love on the bike stand.

Features:

  • Functional simplicity - free of unnecessary complexity, the frameset strikes a perfect balance between high-performance reactivity and all-day comfort. Lighter than the previous generation, the Giant Defy SL 1 delivers a "less is more" experience that modern endurance road riding actually calls for.

  • Engineered compliance - the Advanced SL-grade composite frame and fork are specifically built for long-distance road riding, smoothing out fatigue over big miles. New D-Fuse components work together across the bike to absorb road shocks and vibrations, so you arrive at the finish feeling stronger than you have any right to.

  • Total control - a new Contact D-Fuse handlebar brings ergonomic shaping and an 8-degree flare for comfort and control across full-day rides. Wide, hookless carbon rims with a 22.4mm inner width are optimised for high-volume tubeless tyres up to 38mm, and the 40mm rim depth keeps handling stable and predictable when crosswinds pick up.
Available now in the UK, this is a serious endurance machine at a specification level that rivals bikes costing considerably more.
