Never heard of a Dorado, and cant find out anything online. Hoping someone here knows something about it. The guy I got it from said it was expensive back in the day (I know that means nothing) Seems to have some nice parts on it. Sakae cranks, cool rat traps, suntour components if I remember correctly, shifters are mounted on the brake levers which ive never seen before. Tioga grips. He also said it was made in California, cant verify that though. Any help would be appreciated. Thanks
