SRAM DUB English Bottom Bracket - English/BSA | 73mm | MTB SuperBoost +
What frame standard does the SRAM DUB English BSA 73mm MTB SuperBoost+ fit?
The SRAM DUB English BSA Bottom Bracket at 73mm for MTB SuperBoost+ is built for frames running the SuperBoost+ rear axle standard — 157mm rear hub spacing, which is wider than standard Boost (148mm) and used primarily on fat bikes, some plus-tire platforms, and dedicated downhill or enduro builds that benefit from an even wider chainstay and chainline. SuperBoost+ requires a specific bottom bracket offset to align the chainring correctly with the widened cassette and drivetrain geometry; a standard Boost or non-Boost BSA bracket will produce an incorrect chainline on a SuperBoost+ frame. The oversized DUB spindle interfaces with sealed cartridge bearings and Gutter Seal Technology for all-weather mountain use.
Shell width is 73mm English/BSA threading — standard 1.37" x 24tpi, drive side left-hand thread. Installation requires a standard BSA bottom bracket tool. Verify that your frame explicitly lists SuperBoost+ (157mm) rear spacing and a 73mm BSA shell before ordering — this is not the bracket for standard Boost (148mm) frames. Compatible with SRAM Eagle DUB cranksets designed for SuperBoost+ applications. Check your specific crankset's SuperBoost+ compatibility before building.
