Replacing rear derailleur question
Hi guys hopefully one of you can help me with this I'm sure its been answered before but I have searched and haven't come up with anything.
I aquired an road old bike with a five speed rear hub which I would like to replace with something slightly more uptodate. at the moment its 126mm between the dropouts which I am happy to cold set further apart to fit a more modern hub now the problem I'm having is that the frame has no gear hanger on the (horizontal) dropout and I wondered what my options were be it buy second hand, NOS, or even new if the option exists or something I haven't thought of. Even the technical term for this type of derailleur mounting would help me out in my search on tinternet or alternatively what components names and numbers to look for.
I've done most of the basic bike repairs on mountain bikes etc and I have built a bike up from a bare frame inclusing building the wheels so I'm not trying to do anything off the deepend I just don't want to start mucking about with a frame just to find I can't find components to make it worth while!
First person who says single speed gets a slap
This one isn't for me its for a friend and the budget is not huge.
cheers in advance for all your suggestions
