SRAM DUB English Bottom Bracket - English/BSA | 83mm | MTB
What frame standard does the SRAM DUB English BSA 83mm MTB fit?
The SRAM DUB English BSA Bottom Bracket at 83mm is built for English/BSA-threaded MTB frames with an 83mm-wide shell — a less common but specific standard found on certain downhill, enduro, and older or purpose-built MTB platforms where a wider shell was used to increase chainline offset or accommodate specific frame tube junction geometry. The 83mm shell is wider than the standard 68/73mm MTB BSA width and requires this bracket specifically to achieve the correct chainline. The oversized DUB spindle interfaces with sealed cartridge bearings at the frame, and Gutter Seal Technology improves contamination resistance at the bearing cup-to-shell interface for trail and mountain use.
English/BSA threading uses the 1.37" x 24tpi standard — right-hand on the non-drive side, left-hand (counterclockwise) on the drive side. Installation requires a standard BSA bottom bracket tool; no press equipment needed. Verify your frame's exact shell width is 83mm before ordering, as 83mm is distinct from the 68mm, 73mm, and 100mm BSA MTB variants. Compatible with all SRAM DUB MTB cranksets including GX Eagle, X01 Eagle, XX1 Eagle, and equivalent builds designed for non-Boost frames requiring an 83mm shell.
