When you're racing to win – or even just to improve your performance – every second counts. With the Litening AERO C:68X Race, we've built a UCI-compliant race bike around a frame that's reduced drag by 30%, so you can claw back those marginal gains. The Shimano Ultegra crankset with a built-in 4iiii dual-sided power meter means you can keep an eye on your performance. Newmen Streem Allround 49/54 wheels feature aero profiles and are shod with tubeless-ready 28mm Continental Grand Prix tyres. Shimano's Ultegra Di2 2x12 gears are wide-ranging and incredibly reliable. And matching Ultegra hydraulic disc brakes allow you to go even faster, because you can brake later. No doubt about it – this bike is rapid.<br><br><strong>Frame description</strong><br />Rules are rules. A race bike needs to conform in order to qualify for UCI-sanctioned races. But designing a frame that's significantly more slippery through the air, without breaking the rules? That's completely legit. The Litening® AERO lightweight carbon chassis – built with our premium C:68X material – was designed with extensive use of Computer Fluid Dynamics and real-world wind tunnel testing. The result is a significant 30% reduction in drag, in a fully UCI-compliant frame that elegantly integrates fork, stem, handlebar and seatpost. It's also extremely comfortable and has clearance for tyres up to 28mm. But most important of all, it's very, very fast.
