FAQ

What is the difference between the BBT-47-16 and the BBT-47?: The BBT-47-16 is for 16-notch T47 bottom brackets. The BBT-47 is for 12-notch T47 bottom brackets. Both use a 3/8-inch drive but engage different notch patterns. Using the wrong tool on a premium ceramic bearing bottom bracket risks stripping the cup interface.

Can I use the BBT-47-16 with a torque wrench?: Yes. The 3/8-inch drive is compatible with standard ratchets and torque wrenches. Using a torque wrench and hitting the manufacturer's installation torque spec is strongly recommended, especially for ceramic bearing bottom brackets where overtightening can damage the bearing housing.

How do I know if my bottom bracket is 16-notch?: Check the bottom bracket brand's installation instructions or the BB packaging. The notch count (12 or 16) is typically listed in the specification sheet. If you are installing a CeramicSpeed, Kogel, White Industries, or SRAM T47 DUB bottom bracket, the BBT-47-16 is the correct tool.
