wsi went out of business when cozy there main designer left and started park pre bicycles. cozy yamakoshi is the major reason you are able to ride those bikes. cuz he was wsi's head engineer at the time and designed all those bikes. he was the person in charge of diamond back's huge success at that time. it was his designs and flare that kicked diamond back off. he designed almost all of diamond backs first bikes and most of centurions bikes at that time.. dunno if this helps any but i am marring his daughter . sooo you have any questions on centurions i might be able to help..
