The Cube Litening AIR C:68X Pro 2027 bike featured here at Escapa is an ultralight road bike designed to excel on mountain passes, during accelerations, and in hilly races. Its C:68X carbon frame weighs approximately 799 grams, while the complete bike weighs just 7.2 kg, offering immediate responsiveness when the road slopes or it’s time to attack.
The build combines the 12-speed SRAM Force AXS E1 electronic drivetrain with an integrated power meter, Newmen Streem C.35/38 carbon wheels, and Continental Grand Prix 5000 S TR tires. The result is a fast, precise bike ready to race from the very first ride.
C:68X Frame Weighing Just 799 Grams
The Litening C:68X Air Monocoque frame uses tubes optimized to balance aerodynamics, stiffness, and low weight. Its construction is designed to transform every watt into forward momentum, providing an exceptionally lively response on climbs, sprints, and changes in pace.
C:68X technology combines selected carbon fibers with nanoparticle-reinforced resin. The Advanced Twin Mold process keeps the fibers correctly positioned during curing and allows the material density to be tailored to the loads in each area, eliminating unnecessary weight without compromising strength.
The frame features fully internal cable routing, Flat Mount brakes, an integrated seatpost clamp, and tire clearance for tires up to 34 mm. It also complies with UCI design and construction standards for competition bicycles.
Road Climbing Geometry
The Road Climbing geometry is designed to deliver agility and direct power transfer on climbs. Its compact rear end promotes acceleration, while its precise handling facilitates line changes on technical climbs and descents.
Despite its clear Racing focus, the Litening AIR maintains the balance and comfort needed to tackle demanding training sessions, long-distance rides, and extended days of competition.
IC Aero Integrated Cockpit
The IC Aero Cockpit System integrates the handlebars and stem into a single carbon structure. The wiring runs entirely internally, providing a clean, aerodynamic front end that’s protected from potential external damage.
Its geometry combines a 125 mm drop, 72 mm Reach, -10° rake, 5° frontsweep, 6° flare, and 2° outsweep. It also features an aerodynamic spacer system and an interface for mounting a Garmin-compatible bike computer mount.
SRAM Force AXS E1 Drivetrain
The SRAM Force AXS E1 2x12 wireless drivetrain offers fast and precise electronic shifting, with no visible cables in the Cockpit. Its operation can be customized within the AXS ecosystem to tailor the shifters’ response to each rider’s style.
The SRAM Force AXS E1 crankset features a potentiometer integrated into the spider and 48/35-tooth chainrings. It is paired with a 10-36T SRAM Force XG-1270 E1 cassette, providing a versatile gear range to tackle both steep climbs and fast descents.
Integrated Power Meter
The SRAM power meter allows you to monitor intensity and manage effort with objective data during training and competitions. Its integration into the crank spider provides a clean solution that’s ready for watt-based training from day one.
SRAM Force Hydraulic Brakes
The SRAM Force AXS E1 HRD hydraulic disc brakes offer powerful, progressive, and easy-to-modulate stopping power. The 160 mm rotors on both wheels deliver consistent performance on long descents, fast corners, and in variable weather conditions.
The Flat Mount setup helps preserve the frame’s aerodynamic lines and integrated aesthetics.
Newmen Streem C.35/38 Carbon Wheels
The Newmen Streem C.35/38 Carbon wheels feature a differentiated profile of 35 mm in the front and 38 mm in the rear. This configuration is designed to minimize weight, provide stability in crosswinds, and maintain good aerodynamic efficiency on varied terrain.
The set includes 21 spokes on the front wheel and 24 on the rear, Center Lock mounting, 12x100 and 12x142 mm thru-axles, and Tubeless Ready compatibility.
Continental Grand Prix 5000 S TR 30 mm
The Continental Grand Prix 5000 S TR 700x30C tires offer a balance of speed, grip, and comfort. Their Tubeless Ready construction allows for tire pressures tailored 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 larger tire volumes when seeking extra 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, helping to filter out vibrations without compromising lateral stiffness or power transfer.
It’s complemented by the Acid Nuance SLT Carbon saddle, a lightweight, performance-oriented option for road riding.
