I tried to locate some cogs for my Regina Oro 7 speed, and I was unsuccessful. If you do find someone who has them, please let us all know. I really don't want to switch to another freewheel, as I have been taking very good care of this one, but when I move to the left coast next year, I will be needing cogs that are larger than my largest now, which is 19. There is something nice about older Italian things, don't you think? I wouldn't mind a romantic date with Sophia Loren, even if she is in her 60's. Garth on the right coast, Libre.
