Abstract:
1. A bicycle derailleur mounting structure comprising: a base member including a first portion, a central portion and a second portion, the first portion defining a proximal end of the base member and the second portion defining a distal end of the base member relative to the bicycle frame, the first portion having a first side surface, a second side surface with an aperture extending from the first side surface to the second side surface, with a slot defined by two axially facing surfaces disposed between the first side surface and the second side surface, the axially facing surfaces face in an axial direction with respect to a center axis of the aperture, the central portion extending between the first portion and the second portion such that the second portion is spaced apart from the slot and the first portion by the central portion, the second portion being configured to support a derailleur linkage assembly, the aperture extending through the first portion defines a first axis coaxial with the center axis of the aperture and the second portion includes at least one aperture that defines a second axis with a portion of the derailleur linkage assembly being pivotal about the second axis, the first axis and the second axis being non-parallel to one another, the first portion of the base member being attachable to a bicycle frame with the first axis of the aperture extending through the bicycle frame such that the base member pivots about the first axis relative to the bicycle frame; and a stopper having a support portion disposed in the slot between the axially facing surfaces of the slot, and the stopper being configured for setting an angular position of the base member relative to the bicycle frame.
