Problems solved by technology

Although typical rear derailleurs have limited adjustment to accommodate minor mounting changes (small changes in the thickness of the derailleur mounting plate), sometimes for some frames the limited adjustment capability of the rear derailleur is not enough
Also, even if this limited adjustment is adequate, the performance of the rear derailleur may not be optimal when mounted to some frames (e.g., shifting performance may not be as smooth and precise as originally designed)
Furthermore, making such adjustments to the rear derailleur can be cumbersome and time consuming

Abstract

A bicycle rear derailleur includes a base member, a movable member, a linkage assembly and an axial spacing adjustment structure. The base member includes a mounting axle configured to be attached to a bicycle frame. The movable member includes a chain guide. The linkage assembly is coupled between the base member and the movable member to move the chain guide between a retracted position and an extended position. The axial spacing adjustment structure is disposed on the mounting axle between the base member and the frame. The axial spacing adjustment structure includes a removable first spacer and a second spacer, the first spacer having a first axial side facing the frame and a second axial side configured and arranged to engage the second spacer.

Description

technical field [0001] The present invention generally relates to a bicycle rear derailleur. More particularly, the present invention relates to a bicycle rear derailleur that includes an axial spacing adjustment structure that facilitates mounting to vehicle frames having different thicknesses at the derailleur mounting plate. Background technique [0002] Cycling is becoming an increasingly popular form of recreation as well as a mode of transportation. Moreover, cycling has become a very popular competitive sport among both amateurs and professionals. Whether the bicycle is used for recreation, transportation or competition, the bicycle industry is constantly improving the various components of the bicycle. The bicycle rear derailleur is one component that has been heavily redesigned in recent years. [0003] Generally, the rear derailleur has a base member, the chain guide is movably connected to the base member by a linkage assembly, and a movable member, and the bas...
