Company history
Tange Seiki's official company history says Michiaki Tange formed Tange Seiki Co., Ltd. in Osaka in 1979, focusing on bicycle headsets and bottom brackets. It describes the company as a separate third-generation business and documents its development of high-end bicycle components, including the Zero Stack headset. The recorded year is the documented company formation year, not an inferred date for the broader Tange tubing marque.
