CinelliKing II GRX Gravel Bike
The Cinelli King Zydeco II GRX Gravel Bike represents the pinnacle of Italian gravel design, offering a lightweight and aggressive platform for riders who demand elite performance. This carbon monocoque masterpiece has been engineered to be fifteen percent lighter than its predecessor, resulting in a frame that weighs only one kilogram. This significant weight reduction ensures that the bike feels incredibly lively on steep gradients and lightning-fast during accelerations. By utilising Columbus Carbon Monocoque construction and a refined geometry, Cinelli has created a machine that balances the high-stiffness requirements of competitive racing with the necessary compliance for long-distance comfort on rugged trails.
Advanced Engineering and Integrated Control
One of the standout features of this build is the innovative Double Response layup system, which provides a unique carbon fibre structure designed to optimise power transfer without sacrificing vibration damping. This version of the King Zydeco II further elevates the riding experience with its one-piece carbon handlebar and stem system, providing a stiff and ergonomic cockpit that enhances front-end precision. The full internal cable routing creates a sleek, aerodynamic silhouette while shielding your mechanical components from the elements. This ensures that the bike remains reliable and easy to maintain, even when you are pushing through mud and dust on extended off-road adventures.
Precision Shifting and Versatile Components
Equipped with the robust Shimano GRX 12-speed groupset, this bike is built to handle the most demanding terrain with smooth and reliable shifting. The 1×12 drivetrain, featuring a 40t chainset paired with a wide-range Shimano SLX cassette, provides the perfect gearing for both high-speed flats and technical climbs. Stopping power is managed by Shimano GRX hydraulic disc brakes, offering modulated control in all weather conditions. Completed with a durable Mavic Allroad wheelset and Schwalbe G-One Allround tyres, the Bayou GRX is ready to tackle everything from loose gravel to hard-packed trails, offering a truly unparalleled cycling experience for the modern explorer.
