If your bike is orange it is a 1997 with True Temper chromoly not Reynolds 853. I don't know what market you are in but I think some of the prices mentioned would be high in all but the premium areas with out significant investment if a shop gets it ready to sell. You are the only one who knows what kind of rider you would be, 20 mile cruse around town where that bike would be fine or senior shop/group rides with guys and ladies that like to push it and you might want updated fit, lighter weight, etc. If you want a lot more input, post over a the
Classic & Vintage Forum and if you have photos the
