Adjusting a back derailleur is a crucial step in ensuring smooth and efficient gear shifting on a bicycle. A derailleur is a mechanical device that moves the chain from one sprocket to another on the rear wheel, allowing the rider to change gears and adjust the resistance. A properly adjusted back derailleur will prevent the chain from slipping or skipping, and will also improve the overall performance of the bike.
There are several reasons why a back derailleur may need to be adjusted. Over time, the cables that connect the shifter to the derailleur can stretch, causing the derailleur to shift poorly. Additionally, if the derailleur has been bumped or damaged, it may need to be realigned. Adjusting a back derailleur is a relatively simple process that can be done with a few basic tools.
