X.P.S.S. 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 Campagnolo to complete the product's optimisation. They have also reviewed the profile of the chainring teeth to enhance efficiency and compatibility with the 11-Speed chain an
