1990
Cinelli had some bike made up but I am not sure if they entered the US market with them. We have a nice example of a "The Absolute Machine" but it came from a wholesale distributor that may have been considering importing the bikes.
1992
Cinelli had Gary Fisher design a series of mountain bikes to be sold under the Cinelli name. These often used Fisher-labeled parts such as head sets (1.25" Fisher Evolution) and grips with Cinelli-labeled parts such as bars and seats. The bikes featured Italian names such as Ottomilla and Argento Vivo and often featured wild graphics.
1993
The 1992 experiment with Fisher didn't fare very well in the marketplace so the 1992 models were carried over into 1993 which marked the end of the collaboration.
