Checking/replacing a derailleur hanger

Until I saw this video, I had no idea what a derailleur hanger was, or what it did.  It turns out to be a useful part to know about and is easily replaced if necessary...

  1. Well, it might be easy to replace, and then again it might not?

    Firstly, there are many different shapes and sizes of hangers - just take a look at this St John Street Cycles page to get some idea of the number of variations - http://www.sjscycles.co.uk/page/find/?name=derailleur%20hangers&page=1

    Secondly, some bike frames do not have detachable hangers - they are part of the metal work of the frame

    Thirdly - there are probably other types as well, but my knowledge of bikes is limited

    Hangers are not a problem for those with hub gears though :-)

    So if you are of a cautious nature, go and see what type of hangers are on your bikes and see if you can source replacements.
