When we set out to develop an ultralight race bike, the Litening AIR C:68X SLX was exactly what we had in mind. Comfortable enough to race all day and weighing in at around 799g for a mid-sized frame, it's the UCI-compliant speed machine to help you maximise your performance, whether that's devouring a mountain pass or sprinting for the line. Sram's Red AXS gears – with built-in power meter – and brakes handle stop-and-go duties with precision and predictability, while Newmen Streem Climbing 35/38 Vonoa carbon wheels – shod with 28mm Schwalbe Pro One Aero tyres – help keep you in full control even as the speed increases. The ultimate race machine? That's up to you.
