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, Cube worked with Team Wanty to develop a frame from their 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 6.9kg 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!
