Motobecane 170 10 Speed Vintage Crankset With Chainrings. Off an early nomade. 40t and 52t Sprockets, I made sure all the chainring and guard bolts are loose,all the threads for pedals and dust caps are good. I know the chain guard is bad,but included. This item is sold as-is no return,so please keep that in mind and ask questions if needed.
