What is the SRAM DUB T47 Bottom Bracket 77mm Road for?

The SRAM DUB T47 Bottom Bracket 77mm is designed for road and gravel frames with a T47 threaded shell at 77mm width. The wider 77mm T47 shell is found on some gravel and adventure frames that use an extended shell for improved bearing placement and stiffness. The DUB spindle system works with the T47 interface for long-lasting, well-sealed performance. Compatible with standard SRAM DUB road and gravel cranksets.

The 77mm T47 shell is a less common specification than 68mm. Confirm your frame specifically uses this wider T47 shell before ordering. For DUB Wide cranksets, see the DUB T47 Wide options.

FAQ

What is the T47 bottom bracket standard?

T47 is a threaded standard using a 47mm shell inner diameter with M47 threads. It combines the serviceability of a threaded BB with the wider bearing spacing of modern press-fit shell widths, reducing creak and improving bearing access.

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

The 77mm version is the Road Wide variant used on frames designed for wider chainline cranksets. The 68mm version is for standard road shell width. 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. Installation is similar to standard threaded BBs but uses a larger tool diameter.

Best For

Road and gravel cyclists on T47-threaded frames running standard SRAM DUB cranksets who need a bottom bracket for a 77mm shell width.
