In 1979, Michiaki Tange, one of Yosujirou Tange’s sons, formed Tange Seiki Co. Ltd. in Osaka Japan and focused on making headsets and bottom brackets.
Seiki means “Precision Machining” and that is exactly what Tange Seiki set out to do – producing headsets and bottom brackets to precise Japanese machining standards and the highest quality possible.
