The Cube Litening AIR C:68X SLT 2027 bike featured here atEscapais an ultralight road bike designed to climb quickly, accelerate instantly, and maintain precise handling on descents. Its C:68X carbon frame weighs approximately 799 grams, while the complete bike weighs just 6.9 kg, placing it very close to the minimum weight limit set by the UCI for competition.
It’s equipped with top-tier components: a 12-speed Shimano Dura-Ace Di2 electronic drivetrain, a 4iiii Precision 3+ dual-measurement power meter, and Newmen Streem VONOA wheels with carbon rims and spokes. A bike designed to compete, tackle major mountain passes, and respond when it’s time to attack.
C:68X frame weighing just 799 grams
The Litening C:68X Air Monocoque frame combines optimized profiles to reduce weight and improve aerodynamic efficiency. Its design is geared toward making the most of every watt applied to the pedals, providing exceptionally quick response on climbs, in sprints, and during changes in pace.
C:68X Carbon Fiber technology combines selected fibers with a nanoparticle-reinforced resin. The Advanced Twin Mold process holds each fiber in place during curing and allows the carbon density to be tailored to the specific loads in each area, eliminating unnecessary material without compromising stiffness or strength.
The frame features fully internal cable routing, Flat Mount brakes, an integrated seatpost clamp, and clearance for tires up to 34 mm. It also complies with UCI regulations for competition bicycles.
Road Climbing Geometry
The Road Climbing geometry has been developed to offer agility and direct power transfer on climbs. Its compact rear end facilitates accelerations, while the precise steering response provides confidence during descents and quick changes of direction.
Despite its distinct racing character, the Litening AIR maintains a level of comfort suitable for racing for hours, tackling long-distance rides, and racking up kilometers during demanding training sessions.
IC Aero Integrated Cockpit
The IC Aero Cockpit System integrates the handlebars and stem into a single carbon structure, reducing the number of components and keeping cables and hoses completely hidden. The result is a clean, lightweight, and aerodynamic front end.
Its geometry combines a 125 mm drop, 72 mm Reach, -10° rake, 5° frontsweep, 6° flare, and 2° outsweep. It also features aerodynamic spacers and an interface for mounting a Garmin-compatible bike computer mount.
Shimano Dura-Ace Di2 2x12
The Shimano Dura-Ace Di2 electronic drivetrain offers fast, precise, and consistent shifting with minimal effort. The ST-R9270 shift levers work in tandem with the RD-R9250-D rear derailleur and the FD-R9250 front derailleur to provide refined, race-ready performance.
The Shimano Dura-Ace FC-R9200 crankset features 52/36-tooth chainrings and is paired with a Dura-Ace 11-34T cassette. This gear setup provides the range needed to maintain high speeds on flat terrain and tackle mountain passes with an efficient cadence.
4iiii Precision 3+ Dual Side Power Meter
The cranks feature a 4iiii Precision 3+ dual-side power meter, capable of independently recording the power generated by each leg. This information allows you to analyze your pedaling balance, manage your effort, and structure your workouts using objective data.
Since it comes standard, the Litening AIR C:68X SLT is ready for watt-based training and racing from your very first ride.
Shimano Dura-Ace Hydraulic Brakes
The Shimano Dura-Ace BR-R9270 hydraulic disc brakes provide powerful, progressive, and easy-to-modulate braking. The 160 mm rotors installed front and rear offer stable performance on long descents, fast corners, and in variable weather conditions.
The Flat Mount setup helps maintain a clean, integrated look and the frame’s aerodynamic lines.
Newmen Streem A.49/54 VONOA Wheels
The Newmen Streem A.49/54 VONOA Carbon wheels feature a differentiated profile of 49 mm in the front and 54 mm in the rear. This combination is designed to provide stability in the front end and greater aerodynamic efficiency in the rear wheel. The wheelset features VONOA carbon spokes—15 up front and 18 in the rear. It also includes a Center Lock hub, 12x100 and 12x142 mm thru-axles, and Tubeless Ready compatibility. This configuration keeps weight low without sacrificing aerodynamic performance on flat terrain, descents, and fast sections.
Continental Grand Prix 5000 S TR 28 mm
The Continental Grand Prix 5000 S TR 700x28C tires combine low rolling resistance, grip, and protection. Their Tubeless Ready construction allows you to adjust the pressure to the rider’s weight and road conditions, improving traction and reducing the risk of pinch flats.
The wheel clearance of up to 34 mm allows for the installation of higher-volume tires when seeking to increase comfort, grip, 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 from the road. This improves comfort during long rides without compromising power transfer.
The build is rounded out with the Selle Italia SLR Racing Replica saddle, designed to provide a sporty and efficient riding position.
