Abstract

A bicycle crank assembly with adjustment orientation system for ovoid toothed chainrings comprising a right crank arm () provided with a fifth torque transmission profile (); a shaft () provided with a second torque transmission profile () which is non-rotatably engaged to said fifth profile (); and a transmission element (), for incorporating toothed chainrings, provided with a fourth torque transmission profile () to non-rotatably engage with the first torque transmission profile () of the shaft (). So, when combining the N2 angular positions provided by the coupling between the right crank () and the shaft () with the N1 angular positions provided by the coupling between the transmission element () and the shaft (), Nt different relative angular positions between the right crank () and the transmission element () are obtained, thus increasing the possible orientations and decreasing the angular increment between consecutive orientations of the crank assembly.
