The late eighties/early nineties Schwinn "Aluminums" are not Paramounts, although they were designed by the Waterford, WI based Paramount Design Group. They were never marketed by Schwinn as Paramounts.
These bikes have a reputation as being very stiff and transmitting road buzz through the frame to the rider. On rough pavement, they're bone rattlers. Some of the harsh ride characteristics can be mitigated with careful selection of tires, but they never developed much of a fan base because of the harsh ride.
