CUBE LITENING AERO C:68X PRO CARBON/BLACK

The Litening C:68X Pro is proof that a race bike can be UCI-compliant, comfortable, light... and very, very slippery through the air. No compromise. With its Computer Fluid Dynamics-designed chassis, Newmen STREEM wheelset and Sram Force 2x12 gears, you'll not find a more aerodynamically efficient bike in the peloton. A Comfort Flex seatpost and wider tyres keep things comfortable for the long haul, so you can perform at your best. And powerful Sram Force hydraulic disc brakes add stopping power so you can go faster, for longer.

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.
