I remember them vaguely... No help I know but at least you know you are not mad!
They did exist, however since Raleigh bikes have sold out to the dark side and are now just an 'importer' they have no interest in their own history. I tried to get a warranty on my Dyna Tech Ti road bike and they basically suggested that I should have got a new bike years ago!
Keep the faith, build what YOU want and bollox to anyone else. Just remember that every time you ride it they will never build another bike here! That's what I do on my Pace and my 2 Dyna Tech's.
Somerset, like 'Heartbeat' with newer cars!
