Stelbel

Stelbel was founded by Stelio Belletti, who has been passionate about racing bicycles ever since he was a boy. Starting in the 70s, he began to race in local and amateur competitions with excellent results. Spurred by a dry-spell in his family’s workshop and the dissatisfaction he felt towards the most recent racing bicycle he had purchased, Stelio Belletti tried his hand at bicycle frame building. His results encouraged him to found the Stelbel brand in 1973. Having honed his TIG welding skills while working in the aviation industry, he became the first Italian frame builder to build TIG welded frames. In 1975, Stelio Belletti patented the first bicycle frame welded with TIG welding techniques in Italy and that same year produced the frames for the Polish national team, who went on to win the gold medal in the men’s team time trial race at the UCI Road World Championships in Mettet. By the second half of the 70s, the Belletti workshop concentrated on the production of Stelbel bicycle frames and gradually began to decrease their commitment in other areas of production. In the early 80s, for age reasons, his father Antenore left the company to Stelio, and under his management, the company hired additional employees.

Stelio Belletti is recognized to have been at the forefront of bicycle frame construction, always pushing the boundaries and experimenting with new solutions. He remembers being one of the first manufacturers to make stainless steel frames. Belletti continued to work in his family’s workshop until 1990 when the company closed. Over the following years, Belletti collaborated with other Italian brands producing TIG welded frames made with steel or aluminum tubing. Upon his retirement, Stelio Belletti has devoted his time to sports, participating in several cycling events, and even organizing some himself.
