I have just put up a Motobecane Team Champion frame and fork on Ebay. This is a really nice frameset in great condition but too big for me. It is 57 c to c seat tube with a 58 c to c top tube.I am judging it is late 70s to early 80s based on the Campy grupo it came with (which I am holding on to). It has a chomed fork crown which is in verygood+ condition.
