Cube Litening Air C:68X Slx 2025

When we set out to develop a new ultralight race bike, the Litening AIR C:68X SLX was what we had in mind. Slippery through the air, comfortable enough to race all day and weighing in at around 799g for a mid-sized frame, it's the UCI-compliant speed machine you've been looking for. Sram's Red AXS with built-in power meter handles stop and go duties, while Newmen Streem Climbing 35/38 Vonoa carbon wheels – shod with Continental tyres – help keep you in full control even as the speed increases. The ultimate race machine? That's up to you.

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 6.6kg 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!
