SRAM DUB English Bottom Bracket - English/BSA | 68/73mm
What frame standard does the SRAM DUB English BSA 68/73mm standard MTB fit?
The SRAM DUB English BSA Bottom Bracket at 68/73mm is the standard non-Boost MTB variant — threaded English/BSA at 1.37" x 24tpi, compatible with both 68mm and 73mm shell widths used on non-Boost mountain bike frames. This is the bracket for older or current non-Boost MTB frames, hardtails, and any mountain build where the rear axle spacing is 135mm or the frame was designed before Boost spacing became the MTB standard. The oversized DUB spindle replaced the predecessor GXP standard with a stiffer interface and broader compatibility across bottom bracket shells. Gutter Seal Technology adds weather resistance at the bearing cup interface, and sealed cartridge bearings run cleanly through extended trail use.
Installation is threaded BSA — standard cup wrench, no press required, grease the threads before installation. Both 68mm and 73mm shell widths are covered by this bracket, which accommodates the small dimensional difference between the two MTB BSA standards. Compatible with all current SRAM MTB DUB cranksets in non-Boost configurations including GX Eagle, X01 Eagle, XX1 Eagle, and equivalent builds. If your frame is pre-Boost or explicitly non-Boost MTB with English/BSA threading, this is the bracket for your build.
