Internal T47 Bottom Bracket

Internal T47 Bottom Bracket

Price range: $138.00 through $299.00

White Industries internal T47 style bottom brackets are made here in our shop and feature Enduro stainless steel angular contact bearings or optional Enduro XD-15 ceramic-hybrid radial bearings.  We offer them with three different bearing sizes to help you fit your favorite crank to your favorite bike.  “T47” is a bottom bracket standard that White Industries helped develop in 2016 and allows for a greater weld area for bigger frame tubes as well as room inside the shell for internally routed cables and wires

Product Details

The “T” stands for “threaded” and the “47” is the nominal 47mm outside thread diameter of the cup. T47 bottom bracket cups are not compatible with the much smaller (and more common) threaded BSA 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 our “external” T47 bottom brackets where the bearings sit “outboard” of 68mm and 73mm wide bottom bracket shells.  If you have a 68mm or 73mm wide T47 bottom bracket shell on your frame, you will need one of our "external" T47 bottom brackets.
