There are these rules - and a road bike has to comply with them to be eligible for UCI races. So we set about making the Litening C:68X® Pro carbon frame even more aerodynamic without breaking the rules How did we achieve this? With the help of our high-quality C:68X® composite material, complex CFD analyses and wind tunnel tests under real conditions. The result is 30% less drag in the form of a completely UCI-compliant chassis that includes fork, stem, handlebars and seat post, resulting in a fully integrated set-up. At the same time, this racer is super comfortable to ride. It offers tire clearance for tires up to 28 mm wide and can be used with all current power measurement systems. But its specialty is and remains: speed, speed and more speed !
