Abstract: A bicycle wheel securing device comprises a shaft, an axial abutment structure, a bicycle-body engaging structure, a manual actuator, and a shaft-end retaining structure. The shaft has a first shaft end, a second shaft end, and a longitudinal center axis. The manual actuator is operatively connected to the axial abutment structure to bias the axial abutment structure against a first wheel attachment part of a bicycle body in response to operation of the manual actuator in a securing state where the bicycle-body engaging structure is engaged with a second wheel attachment part of the bicycle body. The shaft-end retaining structure is at least partly disposed at the second shaft end to retain the second shaft end in the first wheel attachment part in a maintenance state where the second shaft end is positioned in the first wheel attachment part of the bicycle body.

Abstract: A first sprocket includes a first opening having a first diameter smaller than a radially outer diameter of a sprocket support portion of a bicycle rear hub assembly. A lock member includes a main body, a male thread portion, and a radial projection. The main body has a first axial end configured to pass through the first opening and a second axial end opposite to the first axial end in an axial direction. The male thread portion is provided to the first axial end and configured to engage with a female thread portion of the bicycle rear hub assembly in a state where a bicycle rear sprocket assembly is mounted to the bicycle rear hub assembly. The radial projection extends radially outwardly from the second axial end to restrict axial displacement of the first sprocket with respect to the sprocket support portion in the state.

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 bicycle derailleur comprises a base member, a movable member, and a chain guide. The chain guide comprises an inner guide plate, an outer guide plate, at least one pulley axle, and at least one pulley. The chain guide is configured to be movable between a plurality of shifting positions. The at least one pulley is configured to be movable between the inner guide plate and the outer guide plate within a maximum pulley movable amount in a pulley axial direction with respect to a rotational center axis of the at least one pulley. A single shifting distance is defined between adjacent shifting positions of the plurality of shifting positions. A ratio of the maximum pulley movable amount to the single shifting distance ranges from 0.21 to 0.35.

Abstract: A bicycle sprocket assembly comprises a first sprocket and a second sprocket. The first sprocket includes a first sprocket body, first sprocket teeth, and a first pitch circle. The first pitch circle has a first diameter. The second sprocket includes a second sprocket body, second sprocket teeth, and a second pitch circle. The first sprocket teeth include a large-sprocket downshifting tooth and an additional large-sprocket downshifting tooth. The second sprocket teeth include a first small-sprocket downshifting tooth, a second small-sprocket downshifting tooth, a first adjacent tooth, and a second adjacent tooth. A circumferential area is defined from a driving surface of the first adjacent tooth to a non-driving surface of the second adjacent tooth in a driving rotational direction about a rotational center axis when viewed in an axial direction. The large-sprocket downshifting tooth is disposed in the circumferential area when viewed in the axial direction.
