Abstract
A bicycle sprocket having a rotational center axis comprises a sprocket body and a chain engagement structure. The sprocket body is rotatable about the rotational center axis. The chain engagement structure includes an upshifting facilitation area configured to facilitate upshifting. The chain engagement structure includes a plurality of chain-engaging teeth configured to engage with a bicycle chain. The plurality of chain-engaging teeth includes at least three upshifting facilitation teeth configured to facilitate upshifting. The at least three upshifting facilitation teeth are adjacent to each other without another tooth between the at least three upshifting facilitation teeth. The at least three upshifting facilitation teeth are provided in the upshifting facilitation area.
