Tange

Tange Seiki Co., Ltd. of Japan builds bicycle headsets. What we stock are the threadless ahead headsets in every common standard: external cups (EC) in 1 and 1-1/8 inch, semi-integrated (ZS44/28.6) and integrated for tapered head tubes (IS42/28.6 on top, IS52/40 at the bottom). The cups are aluminium, the sealed cartridge bearings can be replaced individually, and a compression ring, a crown race and a star nut come with every set. The bearing series carries the Technoglide name.
