摘要： A right crank arm assembly (1) for a bicycle, comprises a right crank arm (5) and at least one front sprocket (10) coupled with the crank arm at at least one coupling portion (44) of the crank arm. The front sprocket (10) has an inner side adapted, in use, to face towards the frame of the bicycle and an outer side opposite the inner side. The assembly (1) comprises at least one first crank arm element (30) which acts in contact with the front sprocket (10) on one of said sides and at least one second crank arm element (35) which acts in contact with the front sprocket (10) on the other of said sides. The contact action of the crank arm elements on the two opposite sides of the front sprocket prevents the twisting deformation of the front sprocket during pedalling. Such a deformation would cause a reduction in the transmission efficiency of the right crank arm assembly.

摘要： A right crank arm assembly (200) for a bicycle, comprises a right crank arm (205'), a first annular element (215') directly coupled with said crank arm (205') at at least one first coupling portion (99) of said first annular element (215') and at least one second annular element (216) coupled with said crank arm (200') and of a smaller size than said first annular element (215'). The first annular element (215') comprises a toothing (100) that extends radially towards the outside along a primitive circumference having a predetermined diameter. Said at least one first coupling portion (99) is entirely contained in a first area extending radially towards the outside starting from an ideal circumference having a diameter at least equal to 2/3 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.

摘要： The derailleur (10) comprises an articulated quadrilateral mechanism, with four parallel articulation axes (A, B, C, D); at a first articulation axis (A), between a fixed member (13) and a first connecting rod (14), the fixed member (13) comprises a first forked structure (62) that embraces the first connecting rod (15); the first forked structure (62) comprises two opposite flanges (63, 64) provided with respective holes (65, 66) aligned along the first articulation axis (A) and the first connecting rod (14) comprises a hole aligned with the first articulation axis (A); a pin (68) is inserted into the two holes (65, 66) of the first forked structure (62) and into the hole of the first connecting rod (14).
The provision on the fixed member (13) of the forked structure (62) that embraces the first connecting rod (14) allows a better distribution of the stresses induced in the first connecting rod (14) and on the pin (68) by the traction of the command cable of the derailleur (10).

摘要： The invention relates to a motion transmission system of a bicycle, comprising a sprocket assembly (16) adapted to be mounted on a freewheel body (22) of a hub of a bicycle rear wheel and a bicycle chain (15) adapted to engage the sprockets (1-11) of the sprocket assembly (16). The sprocket assembly comprises at least eleven sprockets. The hub is able to rotate about a rotation axis (X) and comprises a plurality of spoke attachment seats and a fastening portion to a frame (53) of the bicycle. On the hub a predetermined axial distance is defined between a plane (Z), substantially perpendicular to said rotation axis (X), comprising the points of the spoke attachment seats closest to the freewheel body (22) and a plane (Y), substantially perpendicular to said rotation axis (X) and defined in the fastening portion to the frame (53), comprising the attachment points to the frame closest to the freewheel body (22). All of the sprockets of said sprocket assembly, when associated with the freewheel body, have an overall axial bulk that is lower than or equal to said predetermined axial distance. The chain (15) has a maximum thickness comprised between 4.6 mm and 5.8 mm.

摘要： A chain guide (3) for the front derailleur (1) of a bicycle, comprising a first plate (4) intended to shift a chain from a first toothed crown to a second toothed crown with a larger diameter, a second plate (5) facing said first plate (4) and intended to shift said chain from said second toothed crown to said first toothed crown and connecting means (7) between said first plate (4) and said second plate (5). The first plate (4) comprises a first thrusting portion (41) for shifting said chain from said first toothed crown to said second toothed crown. The first thrusting portion (41) is defined on a projection (46) in turn defined at a first plate portion (410) and having a lower profile (450) that projects with respect to the lower profile of the remaining plate portion (451,452). It is thus possible to minimize the size of the other portions of the first plate, thus achieving a weight reduction of the chain guide, without altering its performance or reducing its structural strength.
