Overview
Cube Litening AIR C:68X SLT
A 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, we worked with pro peloton riders 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 6.8kg bike, but – with details like Full Internal Cable Routing, careful tube profiles and our IC Aero One-Piece Carbon Cockpit – it's still slippery through the air, incredibly good at translating pedalling into forward progress, 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!
The competition won't see you coming. That's not just because the Litening AIR C:68X SLT is fast. Because it is. Very. It's also because the halogrey'n'prizm paint finish that it's wearing is beautifully, subtly understated. With premium, race-proven components and an ultralight C:68X® carbon frame that's fully UCI-compliant, it doesn't need to shout. It's your riding that'll be doing all the talking.
The Litening AIR C:68X SLT takes the UCI rulebook on weight and frame design and translates it into an ultralight, super-efficient carbon race machine whose very essence is speed. From the carbon-spoked, carbon-rimmed Newmen Streem Allround 49/54 Vonoa wheels – shod with 28mm Conti GP5000 S TR tyres – to the carefully honed frame tube profiles, Full Internal Cable Routing and IC Aero handlebar, every detail is focussed on shaving seconds. And Shimano's range-topping Dura-Ace Di2 components – including a crankset with 4iiii 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?
Technologies
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.
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 bike computer. Now you can record and access data wherever you ride, safe in the knowledge that your device is securely mounted and out of harm's way.
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.
Our Integrated Seatpost Clamp is all part of our quest to sweat the details, so that you can reap the rewards. Its minimalist design suits the frame's pared-back aesthetic. And, of course, that's important – because why wouldn't you want your bike to look great? But it also saves a few grammes too. And that matters just as much…
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…
Sleek, light and with a profile that cuts through the air as efficiently as possible, the one-piece carbon IC Aero Cockpit features a 125mm drop and 72mm reach combined with -10˚ rise, a 5˚ frontsweep, 6° flare and 2° outsweep. It's the ideal balance between performance and comfort, whether you're racing or training.
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...
