Technology:

Ultra Torque
Lightweight, stiffness, and easy maintenance: Ultra Torque. Campagnolo has ensured that the two halves of the bottom bracket are inseparably connected to the respective crank arms. This innovation has enabled a significant reduction in the lateral protrusion from the frame, thereby preventing the undesirable contact of the ankles with the crank arms during pedaling. Its assembly is extremely simple, a single oversize screw is used to firmly connect the two halves of the axle. In terms of the effectiveness of momentum transmission, this system is comparable to a one-piece axle.
Moreover, despite the narrow side profile, it has been possible to position the bearings outside the bottom bracket shell, making the axle, which has been given a larger diameter, more rigid thanks to the increased support width. The exceptional performance characteristics of Ultra Torque were achieved through a system derived from motor engineering in the area of clutches and rotational axes: the Hirth joint. This is a coupling connection with self-centering and self-aligning spur gearing, which is located in the center of the inner bearing axle where the ends of the axle halves firmly connected to the crank arms touch each other.
