Product Description

Old School BMX Tange Seiki BB220ST Bottom Bracket for one piece BMX Cranks 

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.
