Whether in competition or during ambitious training, every hundredth of a second matters for speed enthusiasts. That's why we're sending our Litening AERO C:68X Race onto the pavement with a UCI-compliant and, above all, extremely aerodynamic frame that reduces air resistance by 30%. It also features a Shimano Ultegra crank with an integrated 4iiii Dual-Side Powermeter that captures all essential performance data. We've equipped the Newmen Streem Allround 49/54 wheels with aerodynamic profiles and mounted 28 mm Continental Grand Prix tires (tubeless-ready) on them. The Shimano Ultegra Di2 2x12-speed transmission impresses with its wide gear range as well as its exceptional reliability. Also from Shimano are the hydraulic Ultegra disc brakes, allowing for increased speed thanks to later braking. Undoubtedly, this is a fast - no, a very fast - bike!
