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.
