    Abstract: A bicycle sprocket comprises a sprocket body and a chain engagement structure. The chain engagement structure includes a plurality of sprocket teeth. The plurality of sprocket teeth include at least one first tooth and at least one second tooth. The at least one first tooth has a first tooth top extending non-parallel to a sprocket-plane perpendicular to a rotational center axis when viewed from a radial direction of the bicycle sprocket. The at least one first tooth has a first axial chain-engagement width that is larger than an inner link space defined between a pair of inner link plates of a bicycle chain and smaller than an outer link space defined between a pair of outer link plates of the bicycle chain. The at least one second tooth has a second axial chain-engagement width that is smaller than the inner link space.

    Abstract: A bicycle sprocket comprises a sprocket body and a chain engagement structure. The sprocket body has a rotational center axis, a first side and a second side opposite to the first side in an axial direction parallel to the rotational center axis. The chain engagement structure includes a plurality of sprocket teeth. The plurality of sprocket teeth include a plurality of first teeth and a plurality of second teeth. The plurality of first teeth each include an outer-link supporting surface, an opposite surface, and a first radially outermost tooth-tip. The opposite surface is spaced part from the second outer link plate in a state where the chain engagement structure engages with the bicycle chain. The plurality of second teeth each include a second radially outermost tooth-tip that is offset from the first radially outermost tooth-tip of each of the plurality of first teeth in the axial direction.

    Abstract: A method of making a bicycle sprocket having a rotational center axis basically includes providing an annular portion and forming a first tooth and a second tooth. The annular portion is made of a base material and has a plurality of teeth. At least one of the teeth is processed to form a first tooth, and at least one other of the teeth is processed to form a second tooth. The first tooth has a first axial chain engaging width that is smaller than a first axial spacing of an outer link of a bicycle chain and larger than a second axial spacing of an inner link that is coupled to an outer link. The second tooth is formed to have a second axial chain engaging width that is smaller than the second axial spacing. The second tooth is formed by deforming the base material.

    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 and a piston movably disposed within the cylinder to generate fluid pressure for controlling a braking device. The hydraulic fluid pressure generator has an output port that transmits hydraulic pressure generated in the cylinder to outside of the cylinder, and a hydraulic fluid channel coupled to the output port. A connecting part fluidly communicates with the output port through the hydraulic fluid channel, and is connected an external hydraulic hose.
