Wheels Manufacturing T47 Bottom Bracket

This bottom bracket is designed specifically for frames with a T47 threaded shell, which has a 47mm diameter. It is compatible with shell widths ranging from 68mm to 132mm and is intended for use with 24mm spindle cranksets.

The primary advantage of T47 is that it combines the stiffness and wide bearing stance of press-fit systems with the reliability of a threaded interface. This design effectively eliminates the creaking issues commonly associated with press-fit cups while remaining easy to install and service.

You will need a bottom bracket tool with a 44mm x 16-notch interface. This is a common standard, so many existing external bearing bottom bracket tools will work perfectly.

Yes, it comes with a protective sleeve that fits between the cups. This acts as a barrier to prevent dirt, grime, and moisture from contaminating the bearings from inside the frame.
