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.
