Abstract: A shifting system for a human-powered vehicle comprises a controller. The controller is configured to receive a driving torque and a cadence of the human-powered vehicle from at least one sensor. The controller is configured to determine a permitted shift timing based on the driving torque and the cadence. The controller is further configured to control a shift mechanism to perform a gear shift during the permitted shift timing in accordance with a permitted cadence range and a first threshold of the driving torque.

Abstract: A bicycle rear sprocket assembly comprises a first sprocket and a second sprocket. The first sprocket includes a first torque-transmitting profile disposed around a first sprocket opening. The second sprocket includes a second torque-transmitting profile disposed around a second sprocket opening. The first torque-transmitting profile is configured to engage with the second torque-transmitting profile in the mounted state. The first sprocket includes an axial abutment surface configured to axially abut against the second sprocket for axially positioning the first sprocket and the second sprocket relative to each other in the mounted state. The axial abutment surface is disposed farther from an axial center plane of the bicycle rear hub assembly than the first torque-transmitting profile in the mounted state.

Abstract: A bicycle sprocket comprises a sprocket body, a plurality of sprocket teeth, and at least one upshifting facilitation area. The plurality of sprocket teeth extends radially outwardly from the sprocket body with respect to the rotational center axis. The plurality of sprocket teeth includes at least one axially recessed upshifting initiation tooth. The at least one axially recessed upshifting initiation tooth includes a driving surface, a non-driving surface and a tooth tip portion. The non-driving surface includes a non-driving surface protrusion disposed radially inwardly from a non-driving surface side tooth tip end with respect to a rotational center axis. The non-driving surface protrusion has a protrusion tip disposed closer to the second axially-facing surface than the non-driving-surface-side tooth tip end in the axial direction so that a guiding slope extends from the protrusion tip toward the first axially-facing surface.
