The Cube Litening AERO C:68X 2027 bicycle featured here at Escapa is an aerodynamic road bike designed for racing, maintaining high speeds, and making the most of every watt. Its C:68X carbon frame, fully integrated Cockpit, and 60/66 mm Newmen wheels come together to form a package engineered to reduce air resistance without sacrificing competitive weight.
Its single-chainring setup features the SRAM RED XPLR AXS 13-speed electronic drivetrain, a 50-tooth aero chainring, a 10-46T cassette, and an integrated shifter. With a claimed weight of just 6.9 kg, it combines the efficiency of an aero bike with a simple drivetrain and an exceptionally wide gear range.
980-gram C:68X frame
The Litening C:68X Aero Monocoque frame has a claimed weight of approximately 980 grams. Its tubes are aerodynamically optimized and feature fully internal cable routing, Flat Mount brakes, a 12x142 mm rear axle, and a universal dropout (UDH).
C:68X carbon technology uses a blend of selected fibers and nanoparticle-reinforced resin. The Advanced Twin Mold process keeps the fibers properly positioned during curing, allowing the amount of material to be tailored to the loads in each area and reducing weight without compromising stiffness or strength.
The frame also features an integrated seatpost clamp and accommodates tires up to 34 mm wide, expanding setup options based on Terreno and rider preferences.
Up to 6 watts more efficient
The new Litening AERO platform was developed using computational fluid dynamics simulations and wind tunnel testing under real-world conditions. The new frame-and-fork assembly weighs approximately 150 grams less and reduces aerodynamic drag by up to 6 watts compared to the previous generation.
This improvement allows riders to maintain a higher speed using the same power output or keep pace with less energy expenditure. The difference is particularly noticeable during breakaways, relay races, wind-exposed sections, and competitions involving extended periods of high-speed riding.
Aero-Optimized Geometry
The Aero Optimized geometry aims to balance an efficient riding position with the control needed to handle turns, descents, and quick changes in direction. Its development combines aerodynamic testing with cyclists’ experience to achieve stable handling at high speeds and sufficient agility when the road becomes technical.
The bike complies with current UCI regulations for design and construction, making it eligible for official competitions.
IC Aero Max Integrated Cockpit
The CUBE IC Aero Max Cockpit System integrates the handlebars and stem into a single aerodynamic structure. Cables and hoses run entirely through the interior, improving aerodynamic penetration and maintaining a clean, uncluttered front end.
The system includes specialized spacers and an interface for mounting a Garmin-compatible bike computer mount, keeping the device centered and easily visible.
SRAM Red XPLR AXS 1x13
The SRAM RED XPLR AXS E1 13-speed wireless electronic drivetrain eliminates the front derailleur and simplifies the system’s operation. Its single-chainring configuration reduces the number of components, maintains a particularly clean aesthetic, and allows all gears to be controlled from the rear derailleur.
The SRAM RED XPLR XG-1391 E1 cassette offers a 10-46T gear range, combined with an aerodynamic 50-tooth chainring. This configuration provides a very wide range, suitable for maintaining high speeds and tackling hilly routes without resorting to a double chainring.
Advantages of the 1x13 configuration
- Simpler operation, with no front derailleur.
- Fewer components and cables.
- Wide range thanks to the 10-46T cassette.
- 50-tooth aero chainring for high-speed riding.
- Wireless electronic shifting, customizable via AXS.
Integrated SRAM Red Potentiometer
The SRAM RED E1 crankset features a power meter integrated into the spider. This system allows you to monitor intensity, manage effort during a Carrera, and analyze performance after each workout.
Since it’s part of the original build, the bike is ready for power-based training from your very first ride, without the need to install an external power meter later.
SRAM RED AXS Hydraulic Brakes
The SRAM RED AXS E1 HRD hydraulic disc brakes provide power and modulation to control the bike on descents, fast corners, and in variable weather conditions. They are paired with a 160 mm front rotor and a 140 mm rear rotor, balancing braking performance, integration, and weight.
The Flat Mount setup helps maintain the frame’s clean lines and completes the bike’s aerodynamic integration.
Newmen Streem S.60/66 VONOA Wheels
The Newmen Streem S.60/66 VONOA Carbon wheels feature a differentiated profile of 60 mm in the front and 66 mm in the rear. The front wheel prioritizes more predictable handling, while the deeper rear profile is designed to maximize aerodynamic efficiency.
The set features VONOA carbon spokes, with 15 in the front and 18 in the rear. It also features a Center Lock mount, 12x100 and 12x142 mm thru-axles, and Tubeless Ready compatibility.
These wheels are particularly well-suited for fast races, flat courses, triathlons, and cyclists capable of maintaining high speeds over long periods.
Pirelli P ZERO Race SL-R 28 mm
The Pirelli P ZERO Race SL-R 700x28C tires are designed to offer low rolling resistance, grip, and responsiveness in competition. Their Tubeless Ready construction allows for tire pressures tailored to the rider’s weight and road conditions.
The wheel clearance of up to 34 mm allows for the installation of higher-volume tires if you want to gain comfort, grip, or stability on uneven pavement.
Comfort Flex Aerodynamic Seatpost
The Litening C:68X Aero Comfort Flex seatpost combines an aerodynamic profile with controlled flex to help filter out vibrations and impacts from the road. Cube claims an improvement of approximately 10% in comfort compared to a conventional seatpost.
The setup is rounded out with the Selle Italia SLR Racing Replica saddle, designed to maintain an efficient riding position during training and races.
