If your gear system is indexed (clicking between gear shifts), it's best to stick to the same brand rear derailleur as your gear levers.
Rear mechs designed for friction shifting can accept a variety of speed freewheels as long as the largest cogs are not too big for the rear derailleur. We are happy to help if you need any advice on compatibility.
We grade our rear derailleurs by the general aesthetic of the bodies and also by the condition of the jockey wheels. Please refer to the detailed photographs & information below.
