Not all race bikes are created equal. The Litening C:68X SLX's blend of low weight, long-haul comfort and wind-cheating aerodynamics gives you a head start that's entirely UCI-compliant. A Mavic Cosmic SLR 45 wheelset combines wind-cheating design with light weight, while Sram's Red 2x12 wireless AXS groupset puts a wide gear range and awesome stopping power at your fingertips. Carbon comfort, 30% reduced frame drag and fastidious attention to detail means there's no better way to break free of the bunch...
Frame description 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 C:68X's 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, power meter-ready and has clearance for tyres up to 28mm. But most of all, it's very, very fast.
Find your size!
Enter your height and inseam below and click on 'Calculate my frame size' to see which size you need. You measure your inseam as follows:
1. Stand barefoot with your heels against the wall. Place your feet about 6 inches apart.
2. Grab a book and place it between your legs, with the short side of the book against the wall. Press the book up against your crotch, mimicking the idea of a bicycle saddle.
3. Measure the length from the top of the book to the floor, the distance you measure is your inseam.
