I was given a Legnano and a box of parts. There is a Crane GT long-cage on the bike. The bike shop said the cage was bent; however, in the box there was a Campy NR patent 73 rear derailleur. The photographs I have seen online do not depict a hanger bracket. However, on Ebay someone is selling an NR hanger bracket.
My question is how does the Nouvo Record mount to the rear fork? Do I need a hanger bracket for the NR patent 73 short-cage derailleur?
I am new to this forum and vintage bicycles. Any help or comments would be greatly appreciated, thanks!
