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.
