Rossignoli was (is?) a famous shop in Milan. In early 1980s when
we needed some small parts , we usually went to Guerciotti or
Rossignoli. Guerciotti specialized mainly in racing parts but
Rossignoli sold all of the bicycle parts. Small LBS also bought
small parts at Rossignoli. And it had its own brand , from city
bikes to racing bikes.
