SRAM DUB T47 Bottom Bracket - 85.5mm
What frame standard does the SRAM DUB T47 Bottom Bracket 85.5mm fit?
The SRAM DUB T47 Bottom Bracket at 85.5mm fits T47-threaded frames built for MTB Wide chainlines — longer shell width relative to road T47 standards to position the bearings outboard for proper chain alignment on 1x mountain builds. T47 uses the same 47mm bore as press-fit MTB standards but with machined threads, which means installation is repeatable, torque-to-spec, and removable without specialized press equipment or risk of frame bore damage. The oversized DUB spindle works with the full range of SRAM MTB Wide cranksets, and Gutter Seal Technology provides improved weather resistance over earlier SRAM bottom bracket designs. Sealed cartridge bearings run between the spindle and frame with minimal service requirements.
The 85.5mm T47 shell appears on a growing number of modern trail and enduro frames that have moved away from press-fit to eliminate creak without going to a heavier threaded shell design. If your frame spec lists T47 at 85.5mm, this is the correct bracket — not the 68mm road version, not the 77mm road wide version. Compatible with all DUB Wide MTB cranksets including GX Eagle T-Type Wide, X0 Eagle T-Type Wide, XX Eagle, and equivalent trail builds. Confirm shell width and thread standard before ordering.
