Paul David Hewson, known by the nickname Bono, is an Irish singer-songwriter and activist. He is the lead vocalist and primary lyricist of the rock band U2. He also built cycling frames in Italy during the 80's.
Like other posters said they were all made by Vitus factory and re=badged. Graham Weigh cycles put his own decals on alloy Vitus frames back in the 80's and early 90's. They sold well because top rider Sean Kelly rode them at the time.
