What is the SRAM DUB Wide Italian Bottom Bracket 70mm for?

The SRAM DUB Wide Italian Bottom Bracket 70mm is designed for frames with an Italian-threaded shell (70mm width) and is for use with DUB Wide cranksets. Italian threading uses right-hand threads on both sides of the shell, the opposite of BSA, and requires a bottom bracket specifically designed for this standard. The DUB spindle's oversized design delivers the same long-lasting performance and element protection found across the DUB platform, with the Wide version providing the correct bearing position for DUB Wide crank geometry.

Italian-threaded shells are less common than BSA and are found primarily on some European-made frames. Confirm your frame uses Italian threading (not BSA) at 70mm width, and that your crankset is DUB Wide before ordering.

FAQ

How does Italian threading differ from English/BSA?: Italian threading uses right-hand threads on both sides of the shell, opposite to the left-hand drive side thread on English/BSA. Both cups thread in clockwise. The shell width is 70mm rather than the English/BSA 68mm.

What does DUB Wide mean and why can't I use a standard DUB bottom bracket?: DUB Wide positions the bearings for a wider chainline (47.5mm) suited to road and gravel frames using DUB Wide cranksets. Using a standard DUB bottom bracket on a DUB Wide crankset will produce incorrect chainline.

How do I confirm my frame uses Italian threading?: Confirm your frame uses Italian threading at exactly 70mm width and that your crankset is a DUB Wide model. Italian-threaded shells are found primarily on some European-made frames and are less common than English/BSA.

Best For

Road and gravel cyclists on Italian-threaded frames running SRAM DUB Wide cranksets who need the correct bottom bracket for the wider road chainline.
