Compatibility checklist
| Check |
What to confirm |
| Notch count |
Your bottom bracket cup should match a 16-notch interface. |
| Diameter |
Confirm the tool interface is 52.2mm before ordering. |
| Use case |
T47-style bottom bracket installation, removal, and service. |
| Not for |
Bottom brackets with a different diameter, spline, or notch count. |
Why exact measurement matters
Bottom bracket tools look similar online, but a few millimeters or a different notch count can make the tool slip. Match the printed specification on your bottom bracket before using force.
Recommended kit
Pair the socket with a torque wrench, grease or anti-seize as recommended by your frame/component maker, and the matching press or 12T socket if your bike uses more than one interface.
FAQ
Is this for every T47 bottom bracket?
No. T47 refers to the shell/thread standard, but tool interfaces vary. Match 16T and 52.2mm before ordering.
Can home mechanics use it?
Yes, as long as you use the correct torque process and confirm compatibility before applying force.
What if my cup is 12T?
Choose the matching 12T socket instead of forcing a 16T tool.
