Tange Seiki
Tange Seiki has a long and storied history in the bicycle industry.
Yosujirou Tange founded Tange Tekkousho (Tange Iron Works) in 1920 to
produce high end front forks. In 1957, Tange Tekkousho changed its name
to Tange Tekko and continued to produce high end steel and eventually
alloy front forks.
In 1974 Tange Tekko began developing and producing
other high end parts and frame components.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.
Over the course of the next 34 years, Tange Seiki became known as one of
the most innovative headset and bottom bracket brands in the world.
Tange Seiki led the way in high quality headsets such as the Levin
series, first produced in the 1980’s and now have become popular once
again with Fixie, Single Speed, and Retro bikes. In 1999 Tange Seiki
invented the Zero Stack (semi-integrated) headsets which revolutionized
the design of bicycles allowing them to be manufactured much lighter AND
stronger at the same time.
Tange Seiki is a third generation company. Sato Tange, son of Tange
Seiki’s founder Michiaki Tange and Yosujirou Tange’s grandson joined
Tange Seiki in 1984 and became president in 2000. Sato’s eldest son,
Eisuke, nicknamed “Ace”, has joined the company and carries on Tange
Seiki’s commitment to Japanese excellence and standards. No matter where
Tange Seiki products are manufactured, they are all made to the precise
Japanese standard. This philosophy, to produce the highest quality
parts to the highest standards, has been passed from one generation to
another and will continue to guide Tange Seiki for generations to come.
