Actually picked this up last fall, stuck it away for flipping. In moving some stuff around today I pulled it out and looked it over. The previous owner kept it well lubricated. In order to clean it up it needs complete disassembly. Manufactured in USA according to frame decals.
With a little searching it appears they were made from ‘94 to ‘97 or so. Shimano Altus drive train.
