The different type mounting units is detachably attached to a bicycle frame. The movable member is movably supported to the fixed member to move with respect to the fixed member.

Abstract: A front derailleur basically includes a fixed member, a main body, a movable member and a support member. The fixing member is configured to be fixed to a bicycle frame. The main body is attached to the fixing member. The movable member is movably supported to the main body with respect to the fixing member. The support member is movably attached to one of the fixing member and the main body. The support member including an operated portion selectively operated by an operating element and positioned between the fixing member and the main body.

Abstract: A bicycle front derailleur that includes a chain guide configured to engage a bicycle chain and a mounting member operatively coupled to the chain guide. The mounting member includes a frame support structure that includes a contact member that is configured to contact the frame of the bicycle, and a support member mounted to the mounting member. The contact member is supported by the support member.

Abstract: A front derailleur basically includes a fixed member, a main body, a movable member and a support member. The fixing member is configured to be fixed to a bicycle frame. The main body is attached to the fixing member. The movable member is movably supported to the main body with respect to the fixing member. The support member is movably attached to one of the fixing member and the main body. The support member including an operated portion selectively operated by an operating element and positioned between the fixing member and the main body.

Abstract: A front derailleur basically includes a fixed member, a movable member, a driven link and a first link. The fixing member is configured to be fixed to a bicycle frame. The movable member is movably supported with respect to the fixed member. The driven link is operatively coupled to the movable member. The first link movably connects the movable member to the fixed member, and is adjustably coupled to the driven link in a fixed position by a fixing structure to establish a fixed rest position of the movable member with respect to the fixed member.

Abstract: A bicycle derailleur is basically provided with a base member, a movable member and a connecting structure. The base member includes a bicycle mounting portion. The movable member is movable with respect to the base member between a first position and a second position that is farther than the first position from the base member. The connecting structure movably connects the movable member to the base member. The connecting structure moves the movable member with an actuation ratio that descends and then ascends as the movable member moves from the first position towards the second position.

Abstract: A bicycle front derailleur is basically provided with a base member, a movable member and a biasing arrangement. The biasing arrangement is operatively disposed between the base member and the movable member such that a biasing force of the biasing arrangement is smaller during an early range of a movement range of the movable member as the movable member moves from a first position to a second position. The biasing arrangement includes a first biasing member, a second biasing member and a pre-load body. The first and second biasing members selectively bias the movable member. The pre-load body maintains the second biasing member in a loaded state such that the second biasing member applies the second biasing force only after the movable member has partially moved from the first position towards the second position.

Abstract: A chain connecting pin basically includes a pin body, a connecting portion and an inserting portion. The pin body has a first axial end face and a second axial end face, the second axial end face having a recessed surface with respect to an outermost edge of the second axial end face. The connecting portion is attached to the recessed surface of the second axial end face of the pin body. The inserting portion is attached to the connecting portion.

Abstract: A bicycle front derailleur that includes a main body and a chain guide operatively coupled to the main body. The chain guide includes a first plate, a second plate, and a contact member affixed to the first plate. The contact member includes a flexible portion that is adapted to flex when contacted by a chain running through the chain guide.

Abstract: A bicycle front derailleur that includes a chain guide configured to engage a bicycle chain and a mounting member operatively coupled to the chain guide. The mounting member includes a frame support structure that includes a contact member that is configured to contact the frame of the bicycle, and a support member mounted to the mounting member. The contact member is supported by the support member.

Abstract: A front derailleur comprises a base member structured to be attached to a bicycle frame member, a chain guide operatively connected to the base member, and an actuation mechanism coupled to the base member and to the chain guide for moving the chain guide relative to the base member between a first position corresponding to a location for positioning a chain on a first sprocket and a second position corresponding to a location for positioning the chain on a second sprocket. The actuation mechanism is configured so that an actuation ratio of the derailleur when the chain guide is located in the first position is greater than or equal to 1.5 times the actuation ratio when the chain guide is located in the second position.
