Cube Litening Aero C:68X Race Road Bike 2027 Developed using extensive Computational Fluid Dynamics and real-world wind tunnel testing, the Litening AERO C:68X Race delivers genuine aerodynamic gains without compromising its lightweight race credentials. The frame and fork are around 150g lighter than before, while optimised tube profiles and integrated cable routing reduce drag by 4-6 watts. That means less energy spent pushing through the air and more speed generated from every pedal stroke. Ultegra Di2 and Power Meter Precision Shimano Ultegra Di2 2x12 electronic shifting provides fast, precise and dependable gear changes across a wide range of ratios, helping you maintain the perfect cadence as the terrain changes. The Ultegra crankset features a dual-sided 4iiii power meter, giving you accurate power data to help pace your efforts, monitor training and maximise your performance. Matching Shimano Ultegra hydraulic disc brakes deliver powerful, controlled stopping, allowing you to brake later and carry more speed into corners before accelerating away. Race-Ready Wheels and All-Day Speed Newmen Streem Allround 49/54 carbon wheels offer an excellent balance of aerodynamic efficiency, low weight and confident handling, while 28mm Schwalbe Pro One Aero tyres provide the grip and rolling speed required for hard racing. The Cube IC Aero Cockpit and redesigned aero seatpost further streamline the bike, while clearance for tyres up to 34mm gives you the flexibility to tailor the setup to different roads and conditions. The result is a sophisticated, UCI-compliant race bike that doesn't just look fast; it's engineered to help you find those crucial seconds when they matter most.
