Thanks, this really did help. I now own a 1998 Eros bike - the components weren't quite as good this year (Avanti/Mirage), but I was a sucker for getting the lugged frame in Celeste - this is the last year they were lugged. I still might change the cassette on the Castro Valley, though. (Even better, buy a cheap wheel for the trainer and stick the old cassette on that, so that I don't have to swap tires.)
