Designed for road racing and compliant with UCI regulations, the Litening AERO C:68X SLT aims for maximum aerodynamic efficiency while keeping weight in check and delivering full integration.

Key takeaways

• C:68X carbon frame claimed at 980 g, CFD development and wind tunnel testing
• Announced drag reduction: around 30% (vs previous generation, according to Cube)
• Official tyre clearance: 28 mm
• Full integration: internal routing, one-piece cockpit, aero seatpost
• High-end build: Shimano Dura-Ace Di2 2×12 with power meter
• Newmen Streem S.60/66 VONOA carbon wheels (differentiated profiles), tubeless ready
• Claimed bike weight: 7.2 kg

Frame and integration

The Litening C:68X Aero frame (C:68X carbon, Advanced Twin Mold process) features profiles honed in CFD and the wind tunnel. All cabling is fully internal (brakes and drivetrain) via the ICR system, and the fork and seatpost share the same aero shaping. The one-piece carbon cockpit ships with a mount interface for Garmin/Wahoo head units.

UCI compliance is stated for the frame and its design. Available sizes: 50, 52, 54, 56, 58, 60.

Drivetrain and braking

• Groupset: Shimano Dura-Ace R9200 Di2 (12-speed)
• Crankset: Dura-Ace FC-R9200-P with power meter, 52/36
• Cassette: Dura-Ace CS-R9200, 11-34
• Brakes: Dura-Ace BR-R9270, 160/160 mm rotors
• Bottom bracket: Acros Threadfit Ceramic

This build leans on electronic precision, a wide-range 11-34 cassette and powerful disc brakes. The integrated power meter simplifies training and data capture.

Wheels and tyres

Cube equips the Litening AERO with Newmen Streem S.60/66 VONOA wheels (12×100 / 12×142 mm) with carbon spokes and mixed rim depths: shallower up front for handling, deeper at the rear for aero stability. Continental Grand Prix 5000 S TR tyres in 28 mm are tubeless ready.

Comfort and cockpit

The C:68X Comfort Flex aero seatpost promises measured compliance for a performance-oriented frame. The one-piece cockpit targets stiffness and weight reduction, with dedicated aero spacers.

Weight and price

• Claimed frame weight: 980 g
• Claimed bike weight: 7.2 kg (as per spec sheet, size / tubeless state not specified)
• Recommended retail price: €7,699

A pure aero road bike aimed at racing, chasing personal bests and fast group rides. Its main limitation is the official 28 mm clearance, which confines use to good tarmac and road events. Riders seeking the same level of integration but more comfort/volume will find frames elsewhere that accept 30-32 mm tyres.

Our view

The Litening AERO C:68X SLT ticks the modern aero-bike boxes: full integration, a one-piece cockpit, mixed-depth wheels and a Dura-Ace Di2 groupset with power meter. The claimed 30% drag reduction is in line with the segment’s current narrative, comparable to claims from benchmark models (Trek Madone, Canyon Aeroad, Giant Propel, Specialized Tarmac on the more all-round aero side). At a claimed 7.2 kg, the aero-to-weight trade-off looks competitive for a stock Dura-Ace build with deep-section wheels.

Two watch-outs for the discerning buyer: the clearance limited to 28 mm, less generous than some recent alternatives allowing 30-32 mm, and reliance on proprietary components (cockpit, aero post) for future changes. If your riding is predominantly fast and smooth, this Cube delivers a coherent, sharpened package for racing. If you often ride rougher surfaces or want a bit of road/light gravel crossover, better to look at an endurance/aero frame with more tyre volume.
