i think theyre from 1980, but they have legendary status for being a bad idea - dubious benefit if any, more weight and potentially a weak 90 deg corner. Just a cycling curiosity i suppose. What age is the frame? mid-late 80s?
I'm not sure about the age yet, I guess late 80s. The PMP cranks have always interested me, but they are difficult to fit in a group set.
