Wheels Manufacturing T47-OUT-30

This model is specifically designed for frames with a T47 bottom bracket shell that is 68mm wide. Before purchasing, verify that your frame uses the T47 standard, as it is not compatible with threaded BSA or press-fit shells.

This bottom bracket is built for cranksets with a 30mm spindle diameter. If your crankset has a 24mm or 29mm spindle, this specific unit will not be compatible.

The outboard design places the bearings outside of the frame shell, which allows for a wider stance. This configuration generally increases stiffness and stability, leading to more efficient power transfer when you pedal.

It uses ABEC-3 steel bearings, which are known for a good balance of durability and smooth rotation. While these bearings are high quality, they are standard cartridge bearings that can be replaced if they eventually wear out.

Yes, you will need a specific T47 bottom bracket tool to install these cups. Because the cups are external, ensure your tool is compatible with the external notch pattern on the bearing cups.
