My 1980 Schwinn Voyageur did not have rack eyelets, cantilever bosses, or even water bottle braze-ons, but the frame is double-butted chromoly and seems fairly strong. I have replaced just about all the components and have made various adaptations so I could use it for fully loaded touring. I have used it for a couple short tours and it seems to perform well. I still am in a bit of a quandry whether I should buy a new touring bike or simply use this one despite its advanced age and despite it being intended more for sport touring.
