Last week I took the Metro to Levallois Perret to visit Alex Singer Cycles just outside the peripherique of Paris. They've been building bikes for three generations since 1936. From what I understand the shop employs the builder, Olivier Sucain, and one young apprentice. Olivier is the son of builder Ernest Sucain who acquired the business from his uncle in 1964.
