Product Details
This is one of the first products White Industries ever produced way back in 1988. We've updated the design along the way and it remains a popular item all these years later despite the introduction of more "modern" crank and bottom bracket designs. 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 ENO square taper and Road Square Taper cranks as well as other brands that use a J.I.S. (Japanese Industrial Standard) taper such as Shimano, Sugino, and others. These bottom brackets are not compatible with Campy cranks which use an ISO or "Campy" style taper.Specs
