Bicycle rear derailleur of the articulated parallelogram type

A bicycle rear derailleur comprising:

• a plurality of mutually movable components, comprising a support body configured to be attached to a bicycle frame, a chain guide and a pair of connecting arms, comprising a proximal connecting arm and a distal connecting arm, for connection between the support body and the chain guide at respective articulation axes,
• each connecting arm being connected at two points spaced along each of its own two articulation axes, a longitudinal direction of each connecting arm extending orthogonally to and intersecting said two articulation axes, and a transverse direction of each connecting arm extending parallel to said two articulation axes, and
• a limiter assembly effective between (i) a first component selected between the support body and the chain guide and (ii) a first connecting arm of the pair of connecting arms, to define an extreme value of an internal angle of an articulated parallelogram at a vertex corresponding to the articulation axis shared between them,
• wherein the limiter assembly comprises a first member on the first component and a second member on the first connecting arm, to receive the first member in abutment when the first component and the first connecting arm are mutually rotated in the angular direction of approach of the first member to the second member,
• wherein the second member extends at least along an intermediate section in the transverse direction of the first connecting arm.
