Cube Litening Air C:68X SLT 2025 Bike

A performance cyclist is only as good as the bike they're riding. That's why the Litening AIR C:68X SLT blends ultra-low weight with aero performance, full UCI compliance and a suite of race-proven components, so you can race at your best. The liquidlava 'n' black frame finish is just the icing on the cake...

The Litening AIR C:68X SLT takes the UCI rulebook on weight and frame design and transforms it into an ultralight, aero-sleek carbon race machine whose very essence is speed. From the carbon-spoked, carbon-rimmed Newmen Streem Climbing 35/38 Vonoa wheels to the carefully honed frame tube profiles, every detail is focussed on shaving seconds. Shimano's range-topping Dura-Ace Di2 components - with built-in power meter - transfer your power to the road and bring you safely to a stop. There's fast, and there's very rapid indeed. Guess which one this bike is?

An aero bike that reduces wind resistance is great, but a race bike should also - of course - be as light as possible. So, with the Litening AIR C:68X, we worked with Team Wanty to develop a frame from our premium C:68X carbon that combines the best of both worlds. At around 799g for a mid-sized frame it's svelte enough to easily build a UCI-compliant 6.5kg bike, but it's still slippery through the air and comfortable for long days in the saddle. The overall weight saving on a classic road bike is a difference you can clearly feel - and see in your results!

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.

When every second counts, you need your bike's geometry to work with you. Our Road Climbing Geometry's short rear centre and emphasis on agile handling ensures that every fraction of a watt you put into the pedals propels you forward, no matter how steep the gradient. Because gravity sucks, and we're on your side...

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.

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.
