Abstract
A bicycle derailleur comprises a base member, a chain guide, a first link, and a wire guide. The base member is configured to be coupled to a bicycle frame. The chain guide is configured to guide a bicycle chain. The first link is configured to couple the chain guide to the base member so that the chain guide is movable relative to the base member between a retracted position and an extended position. The wire guide includes only one wire guiding portion configured to guide an inner wire of a control cable which is in at least one of a top pull arrangement and a bottom pull arrangement. The wire guide is a separate member from the first link and configured to be attached to the first link.

A bicycle derailleur comprising:
- a base member configured to be coupled to a bicycle frame;
- a chain guide configured to guide a bicycle chain;
- a first link configured to couple the chain guide to the base member so that the chain guide is movable relative to the base member between a retracted position and an extended position;
- and
- one of a wire guide and an additional wire guide which are separate members from the first link and which are selectively attached to the first link, the wire guide including a wire guiding portion configured to guide an inner wire of a control cable which is in a top pull arrangement, the additional wire guide including an additional wire guiding portion configured to guide an inner wire of a control cable which is in a bottom pull arrangement.
A bicycle derailleur comprising:
- a base member configured to be coupled to a bicycle frame;
- a chain guide configured to guide a bicycle chain;
- a first link configured to couple the chain guide to the base member so that the chain guide is movable relative to the base member between a retracted position and an extended position;
- and
- a wire guide which is a separate member from the first link, the wire guide being configured to be attached to the first link so that the wire guide is disposed at one of a first orientation and a second orientation relative to the first link, the second orientation being different from the first orientation, the wire guide including
- a top-pull wire guiding portion configured to guide an inner wire of a control cable in a first state where the wire guide is at the first orientation relative to the first link, and
- a bottom-pull wire guiding portion configured to guide the inner wire of the control cable in a second state where the wire guide is at the second orientation relative to the first link, the bottom-pull wire guiding portion being different from the top-pull wire guiding portion.
