An easy-adjustment bicycle gear-shifting system consisting of a microcontroller unit, a memory, a driver and a derailleur is disclosed. The memory has stored therein more than three position tables each containing the position information of the derailleur relative to the chainrings. The position information contained in one position table has a part or all different from the position information contained in every other position table. The position tables are arranged one after another in a proper order corresponding to one same chainring in such a manner that every two adjacent position tables are differed by a distance value corresponding to one same chainring. The microcontroller unit selects one position table, and drives the driver to shift the derailleur to the corresponding position according to the position information of the selected position table.
