>>2028201Nice bike. The grand jubilee is a mid range model and from that era made in france. The vitus tubing is french and was generally known to be more flexy then tange, colombus, or other brands. Add in the larger frame size(60cm?) and it will be a little flexy.
Looks like some old continental tires on there, a 42-52 crankset, and a nice wide range freewheel.
sigh I can't be assed to shrink my photos right now, but here is one of my vintage rides.
