White Ind. Square Taper Bottom Bracket BSA English Threaded

This is one of the first products White Industries ever produced and remains a popular item all these years later!  This is a BSA “square taper” style bottom bracket which uses BSA threads and a spindle that uses a square/tapered crank arm interface. It is compatible with White Industries square taper ENO and VBC cranks as well as other brands that use a J.I.S. (Japanese Industrial Standard) taper such as Shimano, Sugino, and others. It is not compatible with Campy cranks!
