Campagnolo
Potenza 11-Speed Ultra Torque? Crank
The 4-arm design of the carbon fibre crankset, which gives the Campagnolo Super Record, Record and Chorus groups their inimitable look, has also been integrated into the Potenza group, whose components are made of aluminium.
Ergonomic, reliable and perfectly designed: Campagnolo’s Potenza 11-Speed Ultra Torque? Crank The Potenza crankset is made with both left and right crank arms in hollow forged aluminum to keep weight to a minimum while maintaining the same performance characteristics of its carbon fiber counterparts. Potenza?s 4 arm spider design makes for one single crankarm for all chainring options thanks to its unified bolt pattern which allows for all 3 chainring standards 53/39, 52/36 and 50/34 to be built upon the same crankset. Changing between compact and standard with the Potenza groupset is as easy as changing 8 bolts and two chainrings. While the 4-arm bolt pattern offers advantages in terms of practicality, the Campy Tech Lab designed it primarily with performance characteristics in mind. The 8 bolt pattern with a spider arm design that not only holds the chainring in place by way of the bolt but also supports the chainring and in doing so, increases system rigidity to the point of surpassing its direct competitors in laboratory tests. Features – Potenza 11-Speed Crankset Ultra Torque? NEW HOLLOW CRANKSET: New design (the same shape of the high end groupsets). Both cranks in hollow forged aluminum. ONE SINGLE CRANKSET FOR ALL DIFFERENT CHAINRINGS: All chainrings combinations capability. ERGONOMICS: Design and mechanical performances are aligned to Super Record crankset.

X.P.S.S.? incorporates a project with a specific goal: giving Campagnolo’s new 11-speed groupsets the best shifting performance possible. And the Campy Tech Lab? has hit the mark once again. The new design of the chains up shifting and downshifting has been analysed to the smallest detail with mathematical functions to simulate possible movements of the chain on the chainrings and design optimal angles. Furthermore, repeated lab tests on the speed and precision of the shifting action have allowed us to complete the product’s optimization. We have also reviewed the profile of the chainring teeth to enhance efficiency and compatibility with the 11-Speed chain and the cleverly-shaped derailleur to contribute to making the movement of the chain extremely quick, even under load. Indeed the secret of this amazing result is a perfect combination and integration of all the drive train’s components. Each one of them is designed to perfectly fit and work with the rest. This is the only way you will be able to enjoy the extraordinary performance of the new X.P.S.S.? system.
Power Torque System? Since 2011, 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.
