Cube Litening Aero C:68X Race 2025 Bike

What's the main obstacle to going faster? Air. The Litening AERO C:68X Race's sleek, wind tunnel-tested frame is fully UCI-compliant but also cuts through the air like a hot knife through butter. There's no better way to improve your performance and work your way through the peloton to the podium.

At Cube we know that every second counts. That's why, with the Litening AERO C:68X Race, we've built a UCI-compliant race bike around a frame that's reduced drag by 3% - and fitted a Shimano Ultegra crankset with a built-in power meter, so you're always in the picture. Newmen Streem Aero/Sprint 6/66 wheels feature aero profiles with a shallower profile at the front to reduce the effect of crosswinds. Shimano's Ultegra Di2 2x12 gears are wide-ranging and incredibly reliable. And matching Ultegra hydraulic disc brakes allow you to go even faster, because you can brake later. No doubt about it - it's fast.

Rules are rules. A race bike needs to conform in order to qualify for UCI-sanctioned races. But designing a frame that's significantly more slippery through the air, without breaking the rules? That's completely legit. The Litening AERO C:68X's lightweight carbon chassis - built with our premium C:68X material - was designed with extensive use of Computer Fluid Dynamics and real-world wind tunnel testing. The result is a significant 3% reduction in drag, in a fully UCI-compliant frame that elegantly integrates fork, stem, handlebar and seatpost. It's also extremely comfortable and has clearance for tyres up to 28mm. But most of all, it's very, very fast.

Features

Combining all our expertise from carbon frame building into the ultimate material, C:68X carbon uses the optimum blend of fibre and nano particle-infused resin. Precision Advanced Twin Mold manufacturing means we can avoid bonded sleeves or inserts, too. It's the new benchmark for light, stiff and strong.

Full Internal Cable Routing takes the clutter of external cables and consigns it to the past. We started from scratch, designing frame and handlebars to accept gear and brake cables internally so that nothing interrupts the bike's clean lines. It's neater, it's more aero, it protects cables from damage and it reduces maintenance. All the wins.

If you want to race, there are rules. We know that, which is why all our road race bikes that could be used for racing are fully compliant with UCI regulations on bicycle design and construction. We've created a full range of high performance machines that follow the rules, so you can just concentrate on your performance...

Weight matters when you're chasing every fraction of a second. That's why our one-piece carbon cockpit has been carefully designed to mimic the range of riding positions available with a traditional stem and handlebar combo, but with a substantial weight saving. Light, strong and elegant, it's another way of making every watt count.

Air sucks, and that's why Aero Optimised Geometry matters. Developed with a combination of wind tunnel testing, Computer Fluid Dynamics and feedback from athletes, it's our way of ensuring you can get the best possible performance out of you and your bike. Stable when you need it, agile when it counts and above all very, very fast.

We know that you want to keep track of your performance stats. It's important, which is why we designed a neat, unobtrusive mount for your Garmin. Now you can record and access data wherever you ride, safe in the knowledge that your Garmin unit is securely mounted and out of harm's way.

With our Advanced Twin Mold process we use two precisely manufactured forms for our C:62, C:68 and C:68X carbon frames. The first form is to ensure an accurate layup. The second, inner form keeps every individual fibre precisely where it needs to be while the frame cures. The result is a significantly lighter, stronger frame, with fibre density tailored to anticipated loadings at specific points.
