Cinelli King Zydeco II 2026 — Shimano Ultegra Di2 12s | Fulcrum Rapid Red AL

Some gravel bikes are built for adventure. The King Zydeco II is built for one thing: winning. The fastest, lightest gravel bike Cinelli has ever made, engineered for elite racing performance, maximum responsiveness, and versatility across mixed terrain — the natural choice for riders who treat gravel as a competitive discipline.

Perfect for:

• UCI gravel competitions
• Endurance races
• Fast mixed-surface riding
• Winter training and off-season conditioning

A serious weight reduction

The frame kit is 400g lighter than the original King Zydeco, with a further -273g (size M) thanks to the integrated Columbus Components handlebar and seatpost, and another -92g from aerodynamic and structural streamlining. The result: a frame and fork 6% lighter than the previous generation, for a complete kit that's 15% lighter overall.

Stiffness and ride quality

Bottom bracket stiffness is up 5%, front-end rigidity improves thanks to a more compact main triangle, and the Double Response layup keeps fiber alignment continuous through the seat cluster, cutting vibration on rough terrain.

The drivetrain: Shimano Ultegra Di2 12-speed

This build runs Shimano Ultegra Di2 12-speed — the electronic groupset that brings the same shifting precision Ultegra has made a road standard onto gravel, with gear range management tuned for mixed terrain. Fast, quiet, reliable shifting regardless of conditions — water, mud, dust, it doesn't discriminate.

The wheels: Fulcrum Rapid Red AL

Matched to the drivetrain, Fulcrum Rapid Red AL alloy wheels are built to handle the stress of fast gravel riding while keeping weight in check — the right combination when the surface changes kilometer to kilometer and the wheel just needs to hold up, without you having to think about it.

Columbus Components:

• Integrated handlebar: 380g (420×100mm, painted)
• Seatpost: 215g (350mm, painted)
• 15° flare for enhanced stability
• Proprietary Cinelli seatpost with double-offset locking system (patent pending)
