Seems to me, they were based in Pennsylvania. I remember they used a "salt" bath to clean the frames after building, which seemed like a poor idea to me. However, they sold reasonably good, well made, if heavy bikes. One or two models were outstanding. Some were real duds. I talked an old girlfriend into buying a Ross road bike, and her parents were pissed off at me and her, because the bike cost around three hundred bucks in 1980.
