Abstract: A bicycle hub assembly comprises a hub axle, a hub shell, a sprocket support body, and a clutch. The sprocket support body is rotatably mounted on the hub axle to rotate about a rotational axis. The sprocket support body is rotatable relative to the hub axle and the hub shell about the rotational axis. The clutch has a first coupling state where a pedaling rotational force is transmitted from the sprocket support body to the hub shell in a first rotational direction during pedaling, a first release state where the hub shell is rotatable relative to the sprocket support body in the first rotational direction during coasting, and a second coupling state where a coasting rotational force is transmitted from the hub shell to the sprocket support body in the first rotational direction during coasting.

Abstract: A bicycle sprocket comprises a sprocket body, a plurality of sprocket teeth, and at least one chain-curvature limiting protuberance. The sprocket body is configured to be rotatable about a rotational center axis. The plurality of sprocket teeth extend radially outward from an outer periphery of the sprocket body. The at least one chain-curvature limiting protuberance is configured to limit axial curvature of a bicycle chain engaging with an independent neighboring bicycle sprocket which is adjacent to the bicycle sprocket without another sprocket between the bicycle sprocket and the independent neighboring bicycle sprocket. The axial curvature is curvature of the bicycle chain relative to the bicycle sprocket when viewed from a radial direction perpendicular to the rotational center axis. The at least one chain-curvature limiting protuberance is disposed on at least one of an outward facing side and an inward facing side.

Abstract: A bicycle derailleur is provided that basically includes a base member, a movable member, a chain guide, a biasing element and a rotational resistance structure. The base member is configured to be mounted to a bicycle. The movable member is movably coupled to the base member. The chain guide is pivotally coupled to the movable member to rotate around a rotational axis with respect to the movable member. The biasing element biases the chain guide in a first rotational direction around the rotational axis with respect to the movable member. The rotational resistance structure is operatively arranged between the movable member and the chain guide to frictionally provide rotational resistance to the chain guide around the rotational axis in a second rotational direction. The rotational resistance structure applies the rotational resistance at an area disposed radially outward of the biasing element with respect to the rotational axis.
