SRAM DUB English Bottom Bracket - English/BSA | 100mm | MTB
What frame standard does the SRAM DUB English BSA 100mm MTB fit?
The SRAM DUB English BSA Bottom Bracket at 100mm is built for English/BSA-threaded MTB frames with a 100mm-wide shell — the widest BSA MTB shell standard, used primarily on fat bike frames where extra-wide chainstays and tires require a significantly wider bottom bracket shell to maintain structural integrity and produce the correct chainline for extremely wide rear hub spacing. Fat bikes typically run rear hub widths of 170mm to 197mm, and the 100mm BSA shell positions the bearings outboard to align the chainring correctly with the wide-flanged rear wheel. The oversized DUB spindle interfaces with sealed cartridge bearings at the frame, and Gutter Seal Technology keeps contamination out in conditions where fat bikes frequently operate — snow, mud, and sand.
English/BSA threading at 1.37" x 24tpi — drive side left-hand thread, standard BSA bottom bracket tool for installation. Verify your frame's exact shell width is 100mm and your rear hub width before ordering, as 100mm is a very specific standard distinct from all other BSA MTB shell widths. Compatible with SRAM Eagle DUB cranksets specified for fat bike and wide-shell applications. If your frame spec lists a 100mm BSA threaded shell, this is the correct bracket — no other BSA MTB bracket will produce the correct chainline for a 100mm fat bike frame.
