SRAM's DUB BSA English Threaded 73mm Bottom Bracket fits SRAM DUB crank and frames with 73 millimeter wide, BSA (English) threaded bottom bracket shells.
Aluminum cups, bigger bearings, and nearly impenetrable seals grant the DUB bottom brackets markedly improved durability. Plus, there's a bottom bracket for every frame standard: all you have to do is match the BB to your frame—a DUB crank will fit it.
