FAQ

What is the T47 bottom bracket standard?

T47 is a threaded standard using a 47mm shell inner diameter with M47 threads. It delivers the creak-free serviceability of a threaded BB while accommodating wider bearing spacing than traditional BSA threading.

What is the difference between the 68mm and 77mm T47 versions?

The 68mm version is the standard road shell width used on the majority of road and gravel frames. The 77mm version is the Road Wide variant. Confirm your frame's T47 shell width before ordering.

What tools are required for installation?

A T47 BB tool compatible with the 47mm shell ID is required. Standard BSA BB tools will not fit the T47 shell diameter.

Best For

Road and gravel cyclists on T47-threaded frames running standard SRAM DUB cranksets who need a bottom bracket for the most common 68mm road shell width.
