You've put in the miles, honed your training to perfection, and now it's time to race. The Litening AERO C:68X SLT is the bike you'll need. Built around our C:68X carbon aero chassis with 30% drag reduction, it features Shimano's Dura-Ace 2x12 Di2 groupset – with built-in power meter – for precise gear changes and powerful braking literally at your fingertips. A Newmen Streem Aero/Sprint 60/66 Vonoa wheelset with a lower profile up front gives superb handling and incredible aero performance, even in windy conditions. Tubeless-ready 28mm Continental Grand Prix 5000 tyres combine rapid acceleration with the grip that you need. And the bike's low overall weight and day-long comfort help ensure you'll perform at your peak, hour after hour.<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.
