Cube Litening Air C:68x Race 2026 Road Bike

The CUBE Litening AIR C:68X Race Blackline is built for riders chasing pure speed with uncompromising aero performance. Built around a lightweight C:68X® carbon aero chassis that weighs just ~799 g for a mid-sized frame, it’s designed to be both extremely aerodynamic and feather-light for fast road riding, training and racing. The full carbon fork is engineered to complement the frame’s aero characteristics while enhancing comfort over longer rides. At a complete bike weight that can be UCI-compliant around 7.1–7.3 kg, this bike offers a race-ready platform out of the box.

Shimano’s Ultegra Di2 2x12 electronic groupset with integrated power meter provides crisp, reliable shifting across a wide gear range, while matching Ultegra hydraulic disc brakes deliver strong, progressive control in all conditions. The bike rolls on light, aero-focused Newmen Streem Climbing wheels with Continental Grand Prix 5000 tyres, giving you efficient power transfer and confident grip. Fully integrated cable routing and an aero-optimised cockpit further enhance the clean lines and performance-oriented design of the Litening AIR C:68X Race.
