I have the same bike as the original poster, except i have all of the original parts, I have the same handle bar size as teh guy who posted the 1983 Ross Piranha. My bike looks exactly like that one, but my fork doesn't ahve those holes in the fork
In the 1980's these were released, however, mine was in the Ross Import Devision. Ross did this to try and compete with scwhinn and huffy's mass production in bikes. They shipped the parts to Taiwan, and had them built there because of the cheap labor. Then were shipped to america. Mine was made in Taiwan. Does your bike have the manufacturing location sticker?
Plus I really want the original crank, do you have any of the originals to sell? I will definately purchase A.S.A.P
