The Cube Litening AIR C:68X 2027 bicycle featured here at Escapa is a road bike designed to climb faster, accelerate with ease, and maintain precise handling on descents. Its C:68X carbon frame weighs approximately 799 grams, making it an ultralight platform capable of performing well on long climbs, in races, and on hilly routes.
This version combines the 12-speed Shimano Ultegra Di2 electronic groupset, a 4iiii dual-measurement power meter, Newmen Streem carbon wheels, and an integrated Cockpit. With a claimed weight of just 7.3 kg, it offers a balanced, fast, and race-ready build from day one.
C:68X Frame Weighing Just 799 Grams
The Litening C:68X Air Monocoque frame uses optimized tube profiles to balance aerodynamics and weight. Its construction is designed to make the most of every watt on climbs, maintain immediate responsiveness during changes in pace, and provide the necessary stiffness during sprints.
C:68X carbon combines carefully selected fibers with a nanoparticle-reinforced resin. Thanks to the Advanced Twin Mold process, each fiber remains in the correct position during curing, allowing the amount of material to be adjusted according to the loads on each area. The result is a lightweight, strong, and efficient structure.
Fully internal cable routing, an integrated seatpost clamp, and Flat Mount brakes complete a clean, race-ready frame.
Road Climbing Geometry
The Road Climbing geometry is designed to respond quickly on climbs and during accelerations. The compact rear end promotes direct power transfer, while the agile handling allows for precise line changes on both climbs and technical descents.
Despite its sporty character, the Litening AIR maintains the comfort needed to tackle long races and rides. Its design complies with UCI regulations, making it ready for official competition.
IC Aero Integrated Cockpit
The IC Aero Cockpit System integrates the handlebars and stem into a single carbon structure. This solution reduces weight, improves front-end stiffness, and keeps cables and hoses completely hidden.
Its geometry combines a 125 mm drop and a 72 mm reach, along with a 6° flare and a 2° outsweep. The result is a Cockpit designed to provide an efficient riding position, control on descents, and comfort during training and competitions. It also features aerodynamic spacers and an interface for mounting a Garmin-compatible bike computer mount.
Shimano Ultegra Di2 2x12
The Shimano Ultegra Di2 electronic drivetrain delivers fast, precise, and consistent shifting. The ST-R8170 shifters communicate with the electronic derailleurs to provide smooth shifting, even during intense accelerations or changes in pace.
The Shimano Ultegra FC-R8100 crankset features 50/34-tooth Compact chainrings, paired with an 11-34T cassette. This gear setup provides a balanced range for mountain climbs, rolling terrain, and fast sections.
4iiii Precision 3+ Dual-Side Power Meter
The cranks feature a 4iiii Precision 3+ Dual Side power meter, which measures power from both legs. This data allows you to monitor intensity, manage effort during climbs, and analyze performance after every training session or Carrera.
The integrated power meter makes the Litening AIR C:68X Race a bike ready for training with precise data right from the first ride.
Shimano Ultegra Hydraulic Brakes
The Shimano Ultegra BR-R8170 hydraulic disc brakes provide powerful, progressive, and easily modulated braking. The 160 mm discs fitted front and rear offer consistent response on long descents, fast corners, and in variable weather conditions.
The Flat Mount design maintains integration with the frame and helps preserve the bike’s clean lines.
Newmen Streem A.49/54 Carbon Wheels
The Newmen Streem A.49/54 Carbon wheels feature different rim profiles: 49 mm in the front and 54 mm in the rear. This configuration combines stability in the front end with greater aerodynamic efficiency in the rear wheel.
The set features 21 spokes in the front and 24 in the rear, Center Lock mounting, thru-axles, and Tubeless Ready compatibility. As a result, it offers a balanced combination of lightness, stiffness, and aerodynamic performance.
Continental Grand Prix 5000 S TR 30mm
The Continental Grand Prix 5000 S TR 700x30C tires provide low rolling resistance, grip, and comfort. Their Tubeless Ready construction allows for tire pressures tailored to the rider’s weight and road conditions, improving contact with the road surface and reducing the risk of pinch flats.
The frame accommodates tires up to 34 mm wide, providing room to prioritize comfort and stability on uneven roads.
Comfort Flex Aerodynamic Seatpost
The Litening C:68X Aero Comfort Flex seatpost combines an aerodynamic profile with controlled flex to reduce vibrations transmitted from the road. This helps improve comfort without compromising power transfer or the overall weight of the bike. It pairs with the ACID Nuance SLT Carbon saddle, a lightweight, performance-oriented option for road riding.
