Campagnolo Power Torque Integrated BB Cups - BB 386 86.5 x 46

The Athena 11s, Centaur, and Veloce groupsets feature the Power-Torque system. The new solution was immediately applauded and embraced with enthusiasm thanks to the incredibly high level of performance found in these mid-range groupsets, as well as the ease of use and the high reliability.

The axle is a single piece firmly fixed to the right crank of the crankset. The perfect coupling between bottom bracket and left crank is assured by the special geometry of the two components, a solution that guarantees the maximum reliability.

To make the bottom bracket more efficient, we also worked on the inner part. Thanks to an elaborate sequence of thicknesses, we 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. Only in this way was it possible to achieve such a high technical value.

A careful study of the dimensions made it possible to maintain the lateral measurements already appreciated with the Ultra Torque system, thus guaranteeing the maximum freedom of movement and reducing the possibility of contact with the rider's shoes.

The Campagnolo engineers concentrated on ensuring that installation and servicing would be extremely simple. The most complicated work has been done, so now it's up to you to carry out four simple steps to fit the Power-Torque System crankset quickly and with no potential for error.

The right-hand bearing is already locked in the axle in correspondence with the crankset; the other is pre-inserted in the left-hand cup. No special tool is required, and the new crankset is ready to propel you over endless miles.

That's right, because another one of the objectives of the Power Torque System project was prolonged operating resistance. The tests conducted by the Campy Tech Lab were very exacting in this regard. Now it's your turn.
