PINIOANE CAMPAGNOLO CHORUS 11SP 12-29T Plată securizată

The additional translation provided has led Campagnolo to develop a new carrier structure for the largest six sprockets in two sets of three. Also new is the shape of the teeth with a treatment that causes a longer life.
Eleven pinions that are even more efficient despite reduced pinion strength?
Campagnolo has done it: The shape of the teeth optimizes the speed and smoothness of the chain passage during the shift. With this tooth shape, the stresses acting on the chain are reduced, so that it rises faster on the larger chainrings. The larger sprockets are grouped in groups of three and mounted on a newly developed aluminum support frame. This increases the rigidity by 180% and the individual pinions are 70% more torsionally rigid.
