A bicycle front derailleur is basically provided with a base member, a chain guide and a chain restricting abutment. The base member is configured to be mounted on a bicycle frame. The chain guide is configured to be movably coupled to the base member between a retracted position and an extended position to move a bicycle chain. The chain restricting abutment is configured to restrict the bicycle chain from moving in a radially outward direction of a rotational center axis of a bicycle front sprocket when the base member is mounted on the bicycle frame and the chain guide moves from the extended position toward the retracted position.

A bicycle derailleur comprising a chain guide movable between intermediate positions. An actuation arm associated with the derailleur has a cable seat formed it. A cable-clamping washer includes with a cable-bending appendage that is insertable in the seat of the actuation arm. The actuation arm cooperates with the cable-bending appendage to lock an actuation cable in the desired position.

A compactable bicycle comprising a frame including a first and second frame portions wherein the frame is unfoldable to a use position for riding by the rider and is foldable to a storage position for storage. The bicycle includes: a rear brake, a rear brake lever, a rear break cable passes through a first cable guide, and a brake cable biasing member that is positioned to urge the rear brake cable back through the first cable guide to be between the first cable guide and the rear brake lever; front and rear wheel connectors to hold the front and rear wheels together; a crank, a front sprocket, a rear cassette, rear sprockets, a chain, and a derailleur; a chain guide that is positioned to engage the chain and to limit a lateral angle of the chain relative to the rear sprocket; or first and second frame element locking surfaces and apertures, and a plunger movable to a clamping position and to a release position.

A derailleur comprising a chain guide, a fixed body adapted for being fixedly associated with a part of frame of the bicycle, and an actuation arm hinged to the fixed body. A cable-clamping washer constrained to the actuation arm locks a control cable on the actuation arm. A first fastening station and a second fastening station are defined on said actuation arm and configured to fasten the control cable in different positions on the actuation arm. An anti-rotation appendage projecting from the chain-clamping washer is adapted for being inserted in a holding seat of the actuation arm and holding the control cable in at least one of the first and the second fastening stations.
