SRAM DUB Wide Italian Bottom Bracket - 70mm
What frame standard does the SRAM DUB Wide Italian Bottom Bracket fit?
The SRAM DUB Wide Italian Bottom Bracket is built for frames with a 70mm Italian-threaded shell — the standard found on traditional Italian road frames and some modern carbon builds that carry the Italian thread spec forward. Italian threading is left-hand on the drive side and right-hand on the non-drive side, the opposite of English/BSA standards, so installation tool direction and thread prep matter here. The Wide designation positions the bearings for DUB Wide cranksets running an outboard chainline suited to 1x gravel and adventure builds. The oversized DUB spindle reduces flex compared to earlier narrower spindle designs, and Gutter Seal Technology provides better contamination protection than previous SRAM bottom bracket generations. Sealed cartridge bearings handle the load transfer from crank to frame.
Italian-threaded shells are less common than English/BSA, but they appear regularly on high-end Italian road frames and some custom builds. If your frame spec sheet says 70mm Italian, this is the correct DUB Wide bracket — do not attempt to substitute an English/BSA bracket, as thread pitch and shell width differ. Compatible with all DUB Wide cranksets. Verify your frame's threading standard and shell width before ordering, as the Wide version is specifically for builds requiring the wider outboard chainline.
