put this together for fun from an old frame and parts gathering dust - I didn't want a triple and middle and big rings were riveted together so hacksawed the big ring off - gearing is a mix of ultegra 10 sp rear mech, (70's?) Huret friction shifter on the top tube and a 9 speed shimano cassette minus 1 sprocket on an 6-7-8 sp free hub.
seems to work ok.
