It is versatile thanks to its bolt circle diameter of 123 mm, while giving it an extreme-performance structure, also ensures a greater variety of applications. The smaller BCD on the Chorus crankset makes it compatible with 52\/36, 50\/34 and with 48\/32T chainrings.\u003c\/p\u003e \n \n\u003cp\u003e\u003cu\u003e\u003cstrong\u003eTechnologies\u003c\/strong\u003e\u003c\/u\u003e\u003c\/p\u003e \n \n\u003cp\u003e\u003cstrong\u003eX.P.S.S. (Extreme Performance Shifting System) - \u003c\/strong\u003eX.P.S.S. incorporates a project with a specific goal: giving Campagnolo's groupsets the best shifting performance possible. And the Campy Tech Lab has hit the mark once again.\u003c\/p\u003e \n \n\u003cp\u003eThe 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.\u003c\/p\u003e \n \n\u003cp\u003e\u003cstrong\u003eUltra Torque - \u003c\/strong\u003eCampagnolo found a way to permanently conjoin the semi-axles of the bottom bracket to the respective crankset arms. This redesign made it possible to considerably reduce the lateral dimensions at the axle level and prevent annoying contact with the ankles when turning the pedals.\u003c\/p\u003e \n \n\u003cp\u003eAssembly is simplistic: one single oversize bolt is enough to integrate the two semi-axles.

A distinctive marking, a squared letter as in picture 3, helps recognizing actual shifting components.
