Campagnolo Unisex's Power Torque Bottom Bracket Cups, Black, BSA

Campagnolo Power-torque Ing At/cepo/ve Bottom Bracket Cups. Experience Campagnolo´s Ultra-Torque™ bottom bracket cups, engineered for unparalleled performance and universal frame compatibility. This advanced system seamlessly integrates with any bike, offering exceptional stiffness, low weight, and efficient power transfer. Campagnolo´s ingenious design permanently fuses crankset arms with semi-axles, creating a narrower profile that eliminates ankle interference. Assembly is simplified with a single, robust bolt. By positioning bearings outside the bottom bracket shell and utilizing the Hirth joint technology, derived from motoring expertise, these cups achieve remarkable axle rigidity and self-aligning precision. The Ultra-Torque™ system redefines integrated crankset excellence. Uniquely compatible with all the frames on the market:Technology:- Ultra-Torque™:LIGHTNESS, RIGIDITY, SIMPLIFIED ASSEMBLY AND MAINTENANCE:ULTRA-TORQUE™.THIS IS CAMPAGNOLOS ANSWER IN THE INTEGRATED CRANKSET SECTOR.SIX YEARS AFTER INTRODUCING THE ULTRA-TORQUE™ SYSTEM, IT IS STILL CONSIDERED, THE BEST PERFORMING CRANK-SET SPINDLE IN TERMS OF STIFFNESS, LOW WEIGHT AND EFFICIENCY OF POWER TRANSMISSION.Campagnolo found a way to permanently conjoin the semi-axles of the bottom bracket to the respective crankset arms.This redesign made it possible to considerably reduce the lateral dimensions at the axle level and prevent annoying contact with the ankles when turning the pedals.Assembly is simplistic:one single oversize bolt is enough to integrate thetwo semi-axles.With regard to torque transmission efficiency, this system is equally as effective as a single piece axle.Furthermore, despite the narrow side profile, we have been able to position the bearings outside the bottom bracket shell, resulting in greater axle rigidity from the increased axle diameter.This breakthrough was obtained by using an ingenious mechanical system derived from many years motoring experience in the rotation axle and engine shaft coupling sector:the Hirth joint.In short , this is a joint with self-centring and self-aligning frontal teeth located in the middle of the bottom-bracket axle where the ends of the semi-axles, integrated with the crankset arms, come into contact. tradeinn Bikeinn

For use with Athena, Centaur, and Veloce Power-Torque chainsets where the single piece axle is attached to the right-hand arm of the chainset Careful studies conducted by the Campy Tech Lab engineers allowed material to be removed in zones that could be lightened but at the same time points of stress were strengthened To make the bottom bracket more efficient the axle has varying thicknesses, obtaining an incredibly light axle while offering absolute rigidity Maintaining the lateral measurements already defined with Ultra-Torque guarantees maximum compatibility Campagnolo original replacement part
