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 bicycle shift operating device is provided for operating a shifting device to move a chain between two gears using a guiding portion. The bicycle shift operating device has an operating member, a moving member and a positioning mechanism. The positioning mechanism selectively maintains the moving member in a first position that locates the guiding portion to a first guiding position corresponding to the first gear, a second position that locates the guiding portion to a second guiding position corresponding to the second gear, and a third position that locates the guiding portion to a third guiding position corresponding to the second gear. The third guiding position is farther from the first guiding position than the second guiding position. The positioning mechanism moves the moving member from the first position to the second position in response to a single operation of the operating member.

Abstract: A bicycle sprocket is provided that has a sprocket ring part, a synthetic resin fastening part and at least one attachment part. The synthetic resin fastening part is non-movably coupled to the sprocket ring part at a location radially inwardly of the sprocket teeth relative to the rotation axis. The least one attachment part is at least partially embedded within the synthetic resin fastening part. The attachment part includes a connecting portion and a radial projecting portion extending outwardly from the connecting portion to space the connecting portion radially inward of the sprocket ring part. The attachment part is formed as a separate member from the sprocket ring part and the synthetic resin fastening part. The synthetic resin fastening part facilitates weight saving, while the attachment part prevents the reduction of fastening power (strength) due to deterioration or deformation of the synthetic resin.
