HANGER FOR MOUNTING A REAR GEAR MECHANISM ON A BICYCLE FRAME AND SET OF COMPONENTS FOR SELECTIVELY INSTALLING ALTERNATIVE REAR GEAR MECHANISMS TO A BICYCLE FRAME

摘要

According to one of several aspects of the invention, this also provides a hanger-signable, optionally multi-piece support member (100) positionable on an axial inner side of an associated support portion of the rear support portions of a bicycle frame for supporting an axle of a rear wheel axle assembly of a rear wheel, to mount a rear derailleur of a derailleur to the bicycle frame. The support member (100) includes a first portion having an axis associated with the opening or recess (120, 122) and is exposed in the assembled state in cooperation with other components acting between the rear support portions clamping force, and a second portion, the one opposite the opening or recess (120, 122) in the mounted state relative to the axis radially offset mounting opening (130) on which a terminal end of a base member of the rear derailleur can be fixed. According to the invention, a contact surface surrounding the mounting opening of the second section, which is intended to form a bearing surface for the connection end of the mounted base element, opposite a bearing surface of the first section surrounding the opening or recess on the same side of the support element in the direction of offset from the other side of the support member.
