Abstract: A rear derailleur of a bicycle is disclosed. The rear derailleur includes a four-bar linkage. A fixing pin is received in a blind inner cavity of a base body and a fixing screw is constrained to a frame. A spring loading insert is arranged in the blind inner cavity. The base body is rotatable with respect to the spring loading insert. Connection members are inserted in seats formed on the fixing screw and on the spring loading insert to axially constrain the fixing screw and the spring loading insert. A toothed sector is mounted coaxially to the spring loading insert and is active on a sprocket which is active on the base body. A torsion spring is active between the spring loading insert and the toothed sector and is configured to constrain the spring loading insert and the toothed sector in rotation during controlled movements of the chain guide.

Abstract: A right crank arm assembly for a bicycle, comprises a right crank arm, a first annular element directly coupled with said crank arm at at least one first coupling portion of said first annular element and at least one second annular element coupled with said crank arm and of a smaller size than said first annular element. The first annular element comprises a toothing that extends radially towards the outside along a primitive circumference having a predetermined diameter. Said at least one first coupling portion is entirely contained in a first area extending radially towards the outside starting from an ideal circumference having a diameter at least equal to ⅔ of said predetermined diameter. Such an annular element constitutes the front sprocket of the crank arm assembly of the present invention and consists of a simple toothed band. Such a front sprocket is particularly light in weight.

Abstract: A bicycle gearshift is operated by imposing on the chain guide a primary displacement in the axial direction with respect to a cogset, to move the chain between the sprockets. Simultaneously with imposing on the primary displacement imposing on the chain guide a secondary displacement in the radial direction with respect to the cogset. The secondary displacement is of a greater size when the primary displacement takes place in the area of the cogset with the larger sprockets whereas it is of a smaller size when the primary displacement takes place in the area of the cogset with the smaller sprockets.
