I was given the task of selling these handlebars from a closed bike shop in Minneapolis. These have been on a shelf for over 30 years and were dusty. I have cleaned every set and they are ready for sale once again. These were probably made in Taiwan, they were individually wrapped in plastic and bundled in 5 with twine holding them together. I think they are similar to the GT Performer style bars but will leave that up to your expert eye. I am pretty sure they are mild steel but have no markings on them to give any clue. All these bars seem to have some slight imperfections to them, so they are not 100% perfect. 

I put a set on a '98 Magna I was given and they looked pretty good, I thought. Dimensions are about 25 1/4" wide and 6 1/4" tall as shown, with an approximate 9' overall height.

Just to put it out there, the sale is for the bars and not the bike shown in the last two pics. The bike is shown for reference only.

Feel free to ask any questions and watch for future basement/garage clogging items to come. Thanks for looking, Shannessy.
