This cool vintage frame has a biplane fork and is made of Cromoly tubing. Forget dropouts. This was not a junk bike like later Motobecane offerings. This was from an era when Motobecane made good bikes and this was their attempt to enter the mountain bike market in the early 80s. Similar to a stumpjumper, but more elegant. Size Large, about 20 seat tube and 23.5 top tube.
