What is the SRAM DUB Wide T47 Bottom Bracket 85.5mm for?

The SRAM DUB Wide T47 Bottom Bracket 85.5mm is designed for frames with a T47 threaded shell at 85.5mm width and is specifically for use with DUB Wide cranksets. DUB Wide uses a wider chainline (47.5mm road) to reduce chain angle across wide-range cassettes, and the Wide version of this bottom bracket provides the correct bearing position to match DUB Wide crank geometry in a T47 shell.

Confirm your frame uses T47 threading at 85.5mm and that your crankset is DUB Wide (not standard DUB) before ordering. Standard DUB cranks require the non-Wide version. See SRAM's DUB Road Bottom Bracket selection guide if unsure which version you need.

FAQ

What is DUB Wide and how does it differ from standard DUB?

DUB Wide uses the same 28.99mm spindle diameter as DUB but shifts the chainline outward to 47.5mm to accommodate wider crankset designs used on gravel and adventure bikes. Standard DUB uses a 44.5mm chainline. Only use DUB Wide BBs with DUB Wide cranksets.

What frames use an 85.5mm T47 shell?

The 85.5mm T47 Wide shell is found on gravel and adventure frames designed for a wider chainline. Confirm your frame's exact T47 shell width before ordering, as 85.5mm is different from both the standard 68mm and 77mm T47 road shell widths.

Can I use a standard DUB crank with this bottom bracket?

No. DUB Wide bottom brackets are designed specifically for DUB Wide cranksets. Using a standard DUB crank will result in incorrect chainline.

Best For

Gravel and adventure cyclists on T47-threaded frames running SRAM DUB Wide cranksets who need a bottom bracket for the 85.5mm wide shell specification.
