The rear bicycle gear system consists of a set of gears attached to the rear wheel hub. When the rider shifts gears using the gear shifters on the handlebars, the derailleurs move the chain from one gear to another. This changes the effective gear ratio, making it easier or harder for the rider to pedal depending on the terrain. The rear gear system allows the rider to maintain an optimal cadence and power output while riding. **

The rear bicycle gear shifting system consists of a derailleur that moves the chain across different gears on the rear cassette. When the rider shifts gears using the shifter on the handlebars, the derailleur moves the chain to a different sprocket on the cassette, changing the gear ratio. This allows the rider to adjust the resistance and find the most comfortable gear for the terrain or riding conditions. The rear derailleur is controlled by a cable that is connected to the shifter, enabling precise and quick gear changes. **
