Cube LITENING AIR C:68X SLT Carbon Road Bike 2026
The Cube Litening AIR C:68X SLT Road Bike is engineered for ultimate speed within UCI regulations. Its ultra-light, aero-optimised carbon frame is designed to shave seconds off every ride. Carbon-spoked, carbon-rimmed Newmen Streem Climbing 35/38 Vonoa wheels paired with 28mm Continental GP5000 S-TR tyres provide lightweight acceleration and reliable grip, while every tube profile and component is honed to maximise aerodynamic efficiency.
Litening AIR C:68X SLT Advanced Components
Shimano Dura-Ace Di2 electronic components, including a crankset with integrated power meter, deliver precise gear shifts, efficient power transfer and confident braking. A new aero carbon cockpit further enhances performance, saving up to 8 watts and providing a mount for bike computers to monitor speed, power and progress.
Cube Litening AIR C:68X SLT Ultra-Light Carbon Frame
The Litening AIR C:68X frame weighs around 799g for a mid-sized model and can be built into a fully race-ready 6.6kg UCI-compliant bike. Developed in collaboration with Team Intermarché-Wanty, the SLT version improves aerodynamics with a one-piece carbon cockpit while maintaining comfort and control, combining lightweight engineering with race-proven performance.
