Description of Campagnolo Athena Power-Torque Carbon Crankset 2x11 53/39 - 2015

The most evident changes are immediately noticed on the first shift. The new design of the chain up shift and downshift zones makes shifting extremely fast and precise. The axle of Athena™ is the brand new Power Torque System™, which makes it possible to obtain very high values of torsional stiffness and efficient power transmission, without increasing the lateral bulk.

Features & Benefits

Optimal positioning of the ball bearing seat
Reduces friction to the minimum, reduces mechanical stress, and protects the ball bearings from water and dust to assure consistent performance over time.

Optimized U and Q factors
Space optimized between ankle and crank - maximum lateral and torsional stiffness.

X.P.S.S.™ Extreme Performance Shifting System
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 analyzed 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 Campagnolo to complete the product's optimization.

Campagnolo also has 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™
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, Campagnolo also worked on the inner part. Thanks to an elaborate sequence of thicknesses, Campagnolo was 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.
