Front or Rear: Choosing the Right Derailleur

Essential to the proper functioning of your bike, bike derailleurs can be installed in different locations. The rear derailleur allows you to change the chain's gears from one sprocket to another. The front derailleur is mounted on the frame and lets you change the chain's gears between the chainrings on the crankset.
