According to mombat.org/Specialized_Specs.htm, the pictured bike is a 1989.
1988 had a U rear brake and was 6 speed, 1989 had a canti rear brake and was 7 speed. They both were offered in that paint scheme.
Thanks for the clarification. I should have looked more closely at the bike before I posted. Mine is actually the 6 speed '88 version. That leads me to a tech question, which I've posted
here.
