Derailleur adjustment is the process of fine-tuning the derailleur system on a bicycle to ensure that the chain moves smoothly and efficiently between the different gears. A well-adjusted derailleur will allow for quick and precise shifting, which is essential for maintaining a comfortable and efficient riding experience.
There are a number of different types of derailleurs, but the most common type is the rear derailleur. The rear derailleur is responsible for moving the chain between the different sprockets on the rear cassette. The front derailleur, which is less common, moves the chain between the different chainrings on the crankset.
