I have a similar frame, Zeus 2000 crown, but Campy DO's. Mine came from BC and Cecile when they were still in Holland. There were no decals, but BC said these frame were sold as Zeus frames originally, although there was some thought that they may have been built by a contractor, perhaps one in France. Let's see - Spanish bike with Spanish lugs and Italian DO's built in France, very interesting.
