Campagnolo Ultra Torque Pressfit Bearing Cups
Item number: 41951
Campagnolo's Ultra Torque™ Pressfit bearing cups allow cranks to be mounted in frames with oversize bottom bracket shells.
Low weight, rigidity and easy maintenance: that's Ultra-Torque™. 6 years after its introduction, Ultra-Torque™ is still recognised in terms of strength, weight saving and power transmission as the best performing bicycle bottom bracket spindle. Campagnolo has made sure that the two halves of the bottom bracket are inseparably connected to the respective crank arms. This new development has made it possible to considerably reduce the lateral protrusion from the frame, thus preventing the undesirable contact of the ankles with the crank arms during pedalling. Its assembly is extremely simple, a single oversize screw is used to firmly connect the two halves of the axle. Concerning effectiveness of transmission of momentum, this system can stand comparison with a one-piece axle.
In addition, 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 extraordinary performance characteristics of Ultra-Torque™ have been achieved by using a system that originated in engine construction in the field of hitches and rotary axles: the Hirth™ gearing. This is a coupling connection with self-centering and self-aligning spur gearing, which is arranged in the centre of the inner bearing axle where the ends of the axle halves firmly connected to the crank arms touch each other.
