摘要： A bicycle freewheel body and sprocket assembly is provided. The freewheel body has a predetermined axial width. The sprocket assembly has at least eleven sprockets of various diameters that are arranged on the freewheel body with a largest diameter sprocket and a smallest diameter sprocket forming end sprockets of the sprocket assembly. Each of the end sprockets has an outer face and the respective outer face of each end sprocket faces in an opposite directions and the outer faces are spaced from each other along the freewheel body predetermined axial width. An assembly of at least eleven sprockets has an overall axial width measured between respective outer faces of end sprockets in the assembly that is no greater than 40.5 mm. A chain is comprised of an alternating succession of inner and outer links, connected to each other at respective connection ends.

摘要： 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.

摘要： A right crank arm assembly for a bicycle, comprises a right crank arm and at least one front sprocket coupled with the crank arm at at least one coupling portion of the crank arm. The front sprocket 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 comprises at least one first crank arm element which acts in contact with the front sprocket on one of said sides and at least one second crank arm element which acts in contact with the front sprocket 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 pedaling. Such a deformation would cause a reduction in the transmission efficiency of the right crank arm assembly.

摘要： The bar-end electric actuation device of a bicycle gearshift, comprising a body suitable for being mounted at an end of handlebars facing forwards in the direction of travel (X) of the bicycle and a first and a second electric actuation member acting on respective electrical contacts which are mounted in the body and are suitable for controlling gearshifting, upwards and downwards respectively. The first and the second electric actuation member are faced by said body according to a respective facing direction, angularly spaced apart by an angle (α) that is between 60° and 130°. Moreover, the body is suitable for being positioned externally around the end of the handlebars, leaving free access to the inside of the end itself.

摘要： A sprocket assembly mounted to a hub has at least eleven sprockets. The hub is able to rotate about a rotation axis and has a plurality of spoke attachment seats and a fastening portion to a frame of the bicycle. On the hub a predetermined axial distance is defined between a plane, substantially perpendicular to the rotation axis, comprising the points of the spoke attachment seats closest to the freewheel body and a plane, substantially perpendicular to the rotation axis and defined in the fastening portion to the frame, comprising the attachment points to the frame closest to the freewheel body. All of the sprockets of the sprocket assembly, when associated with the freewheel body, have an overall axial width that is lower than or equal to the predetermined axial distance. The chain has a maximum thickness between 4.6 mm and 5.8 mm.

摘要： A bicycle rear wheel sprocket assembly has twelve sprockets in a twelve sprocket assembly. The twelve sprocket assembly is configured to be mounted to a bicycle freewheel hub. The freewheel hub rotates about a rotation axis and has a spoke attachment portion and a frame fastening portion which are spaced apart by an axial distance. End sprockets of the twelve sprocket assembly are positioned within the axial distance.
