The Cube Litening AIR C:68X SLX 2027 bike featured here at Escapa is an ultralight road bike designed to deliver maximum performance on climbs, sprints, and hilly races. Its C:68X carbon frame weighs approximately 799 grams, while the complete bike weighs just 6.5 kg—below the UCI’s minimum competition weight limit of 6.8 kg.
The SRAM RED AXS E1 electronic groupset, the integrated power meter, and the Newmen Streem VONOA wheels with carbon rims and spokes create a top-tier build. A bike that’s responsive on climbs, fast on the flats, and comfortable enough to race for long days.
C:68X frame weighing just 799 grams
The Litening C:68X Air Monocoque frame uses tubes optimized to balance low weight, stiffness, and aerodynamic efficiency. Its construction is designed to transform every watt into forward momentum, delivering immediate response during attacks, changes in pace, and steep climbs.
C:68X Carbon Fiber technology employs an advanced selection of fibers combined with nanoparticle-reinforced resin. The Advanced Twin Mold process keeps each fiber in the correct position during curing, allowing the carbon density to be tailored to the specific loads in each area and eliminating unnecessary material.
The frame features fully internal cable routing, Flat Mount brakes, an integrated seatpost clamp, and tire clearance for tires up to 34 mm. Additionally, its design complies with UCI regulations for competition bicycles.
Road Climbing Geometry
The Road Climbing geometry is designed to harness the rider’s power when the road slopes upward. Its compact rear end promotes acceleration, while the precise headset allows for quick line changes on technical climbs and descents.
Despite its clearly competitive focus, the Litening AIR maintains the balance and comfort needed to tackle long-distance rides, demanding training sessions, and Carreras lasting several hours.
IC Aero Integrated Cockpit
The CUBE IC Aero Cockpit System integrates the handlebars and stem into a single carbon structure. This design reduces the number of parts, lowers aerodynamic drag, and keeps cables and hoses completely hidden.
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.
SRAM Red AXS E1 2x12 Drivetrain
The SRAM RED AXS E1 12-speed wireless drivetrain provides fast, precise, and customizable shifting. By eliminating shift cables, it helps maintain a clean Cockpit and facilitates seamless integration of the entire system.
The SRAM RED AXS E1 crankset uses 48/35-tooth chainrings, paired with a 10-36T SRAM RED XG-1290 E1 cassette. This gear setup offers a fast gear ratio for riding on flat terrain and a wide enough range to tackle mountain passes and steep climbs.
Integrated SRAM Red Power Meter
The cranks feature an SRAM RED power meter integrated into the spider, allowing you to measure power and manage your effort using objective data. This information is especially useful for structuring workouts, maintaining a constant intensity, and monitoring performance during races.
Since it comes standard, the bike is ready for watt-based training from the very first ride, with no need for a later upgrade.
SRAM Red Hydraulic Brakes
The SRAM RED AXS E1 HRD hydraulic disc brakes provide powerful, progressive, and easy-to-modulate braking. The setup uses a 160 mm rotor up front and a 140 mm rotor in the rear, aiming to balance braking power, weight, and integration. Its ergonomic design allows you to control braking from different positions on the handlebars, ensuring safety on fast descents, technical turns, and in varying weather conditions.
Newmen Streem C.35/38 VONOA Wheels
The Newmen Streem C.35/38 VONOA Carbon wheels feature different profiles—35 mm in the front and 38 mm in the rear. This configuration keeps weight very low, provides stability in crosswinds, and offers improved aerodynamics compared to conventional low-profile wheels.
The set includes VONOA carbon spokes—15 on the front wheel and 18 on the rear. It also features Center Lock mounting, 12x100 and 12x142 mm thru-axles, and Tubeless Ready compatibility.
Its light weight and moderate profile enhance the bike’s climbing capabilities without limiting its performance on flat terrain, descents, or wind-exposed routes.
28 mm Schwalbe Pro One Aero TLR
The Schwalbe Pro One Aero TLR 700x28C tires are designed to deliver speed, grip, and aerodynamic efficiency. Their Tubeless Ready construction allows you to adjust the pressure based on the rider’s weight and road conditions, improving traction and reducing the risk of pinch flats.
The frame accommodates tires up to 34 mm, providing room to mount higher-volume tires when seeking to increase comfort, stability, and grip on uneven roads.
Comfort Flex Aero Seatpost
The Litening C:68X Aero Comfort Flex seatpost combines an aerodynamic profile with controlled flex to reduce vibrations transmitted from the road. This design enhances comfort during long rides without compromising lateral stiffness or power transfer.
The setup is rounded out with the Selle Italia SLR Racing Replica saddle, a lightweight option designed to maintain a sporty and efficient riding position.
