The perfect coupling between central pin and pedal crank is ensured thanks to the particular geometry of the two components; this solution also makes it possible to eliminate the potential play between the different materials. To make the bottom bracket more efficient, they also worked on the inner part. Thanks to an elaborate sequence of thicknesses, they were able to obtain an incredibly light axle while offering an absolute response in terms of rigidity. Thanks to the studies conducted by the Campy Tech Lab engineers, material was removed in the zones that could be lightened but at the same time the points of maximum stress were strengthened. Read more… Only in this way was it possible to achieve such a high technical value. A careful working out of the dimensions made it possible to maintain the lateral measurements already defined with the "elder brother" Ultra Torque, thus guaranteeing the maximum freedom of movement and reducing the possibility of contact with the shoes.
