Basso is still in business (not imported to the US at this time) and claims to make their bikes in Italy: see
www.bassobikes.com . There is still a steel bike in their range, the Viper: I have a one of these from around 2000 and it is a fine frame. The Gap was their basic frame and was constructed in slightly different ways depending on the year. There are other steel frames that were above the Gap in the lineup: Ascot, Loto, Viper, etc.
