Abstract: A bicycle derailleur is basically provided with a base member, a movable member, a coupling structure and an attachment member. The base member is configured to be mounted to a bicycle. The base member has an inner wire guide. The inner wire guide has an inlet portion and an outlet portion. The movable member supports a chain guide. The coupling structure movably couples the movable member to the base member so that the movable member is selectively movable relative to the base member. The attachment member is detachably and/or rotatably attached to the outlet portion of the inner wire guide.

Abstract: A bicycle control device includes a housing member, a control lever member, a shift-operating mechanism and a hydraulic fluid pressure generator. The housing member has an attachment part for attachment to a handlebar, and a grip part extending longitudinally between first and second ends of the grip part. The control lever member pivots respect to the housing member. The shift-operating mechanism is coupled to a shifting device by a control cable. The hydraulic fluid pressure generator has a cylinder, a reservoir, and a piston movably disposed within the cylinder to generate fluid pressure for controlling a braking device. The cylinder is disposed in the housing member at a position closer toward the second end of the grip part than is the shift-operating mechanism to the second end of the grip part. The reservoir is disposed next to the cylinder in a direction intersecting the longitudinal direction.

The housing member has an attachment part for attachment to a handlebar, and a grip part extending longitudinally between first and second ends of the grip part. The shift-operating mechanism includes a cable take-up member rotatably mounted around a cable take-up axis. The cable take-up member has a control cable attachment part that is configured to be coupled to a shifting device by a control cable. The hydraulic fluid pressure generator has a cylinder and a piston movably that is disposed within the cylinder by movement of the control lever member to generate fluid pressure for controlling a braking device. The cylinder defines a cylinder axis that forms an angle of greater than or equal to 20° and less than or equal to 50° with the cable take-up axis.

Abstract: A bicycle operating device is provided with a base member, a brake operating lever and a shift operating lever. The shift operating lever moves from a rest position in a second direction to perform a gear shift operation in response to operation of the shift operating lever by the user. The shift operating lever has a handlebar engagement portion that is moved by a handlebar of the bicycle relative to the brake operating lever in a third direction toward the brake operating lever to move closer to the brake operating lever when the brake operating lever is pivoted in the first direction by the user. The third direction is a non-shifting direction that is different from the first and second directions. The shift operating lever does not perform the gear shifting operation when moved in the third direction by the handlebar of the bicycle.

Abstract: A bicycle operating device comprises a base member, a brake operating member, and a first operating member. The base member comprises a first end portion, a second end portion, and a grip portion. The brake operating member is movably coupled to the base member to operate a brake device. The first operating member is coupled to the base member movably between a rest position and an operated position to move a mechanical control cable relative to the base member. The first operating member is movable relative to the base member between the rest position and the operated position without mechanically positioning the mechanical control cable relative to the base member during a movement of the first operating member occurring between the rest position and the operated position.

Abstract: A bicycle sprocket has a rotational center axis. The bicycle sprocket comprises a sprocket body, a plurality of sprocket teeth, and at least one chain-supporting portion. The plurality of sprocket teeth are circumferentially arranged on an outer periphery of the sprocket body. The at least one chain-supporting portion is configured to contact one of inner link plates of a bicycle chain without engaging with the bicycle chain at inner link spaces each defined between a pair of inner link plates that face each other in an axial direction parallel to the rotational center axis. The at least one chain-supporting portion is offset from the sprocket teeth in the axial direction.
