How do I choose a rear derailleur?
As most bikes will have both front and rear derailleurs, it is pretty much a given that you'll be needing one to shift gears. A good first point to look at is what make the rest of your components are, as it is always a safe bet to match your rear derailleur to those, as some won't be inter-brand compatible. Also pay close attention to the number of gears on your cassette, is it 9, 10 or 11 speed? Following these guidelines will set you up for a good choice.
As usual we offer you the best prices on rear derailleurs, and you can browse our selection below.
