Bicycle single-acted gear-shifting device (), comprising one front or rear derailleur () coupling a ratchet indexing mechanism () acted by only one single-acting slave-connector () attached to said ratchet indexing mechanism (), operated by a unidirectional operator mechanism () with optional multiple unidirectional handle operator units (). Said ratchet indexing mechanism () removably defines and holds a plurality of predetermined working stable positions of the derailleur's cage-plate () for each gearshift, and it comprises a ratchet-gear () with a pawls' system. And said unidirectional operator mechanism () comprises optional multiple unidirectional operator units () connected in parallel with the only single-acting slave-connector (), in order to indistinctly operate it, by means of a branched single-acting drive circuit () which can be arranged either using a hydraulic circuit (&#x2033;) acting by pushing, or using flexible cables (') and housings () to act by pulling.
