T47 is a bottom bracket standard that White Industries helped develop in 2016. The “T” stands for “threaded” and the “47” is the approximate outside thread diameter of the cup. T47 bottom bracket cups are not compatible with the much smaller BSA threaded BB shells.

The “External” designation on this bottom bracket refers to the fact that the bearings sit “outboard” the BB shell as opposed to “inboard” of the BB shell as they do on our “internal” T47 bottom brackets.

White Industries bottom brackets are made here in our shop with U.S. sourced 6061-T6 aluminum and feature Enduro stainless steel bearings as well as a ceramic bearing upgrade option where possible. We offer a wide variety of styles and colors to help you fit your favorite crank to your favorite T47 style bike.
