Made in America T47 BB For Wider Shells

White Industries internal T47 style bottom brackets are made in their Petaluma, California shop with U.S. sourced 6061-T6 aluminum and feature Enduro stainless steel bearings.

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, in millimeters. T47 bottom bracket cups are not compatible with the much smaller BSA threaded BB shells. The "internal" designation on this bottom bracket refers to the fact that the bearings sit "inboard" of 86mm and 92mm wide bottom bracket shells, as opposed to "external" T47 bottom brackets where the bearings sit "outboard" of 68mm and 73mm wide bottom bracket shells.


  • Options to fit Shimano Hollowtech II (24mm) or SRAM DUB (29mm).
  • Dust seals included with all models
  • 47mm x 1mm (T47) threads
  • Designed to be used on 86mm or 92mm wide bottom bracket shells
  • 29mm: 87g / 24mm: 98g
