A bike derailleur is your gear mechanism. It needs to be in top condition to provide a smooth ride and climb hills efficiently. Bike derailleurs are typically made of carbon, aluminum, or steel, and some have plastic components. They can be front or rear mechanisms. A front derailleur fits on your seat tube with a clamp. Some are adjustable and most have 7 speeds, though some have more. Rear bike derailleurs typically range from 6 to 10 speeds. Some are even wireless. Rear derailleurs can have a short, medium, or long cage, which is a component that your bike chain passes through when changing gears. Heavy bike derailleurs can weigh your ride down, so check the weight and get the lightest you can afford.
