SRAM DUB Wide T47 85.5mm Ceramic Bottom Bracket

The SRAM DUB Wide T47 85.5mm Ceramic Bottom Bracket connects your crankarms to the frame using SRAM's DUB spindle standard, an oversized spindle design SRAM built to work across its full range of bottom bracket specs and keep crankarm compatibility simple. This version threads into a T47 85.5mm shell, the wider bottom bracket format paired with SRAM's Road Wide cranksets, and swaps in ceramic bearings in place of standard steel for lower rolling resistance and a smoother, more consistent spin.

Threaded T47 shells install and remove more cleanly than press-fit standards, and this version uses aluminum cups sized for the 85.5mm shell width. Being the ceramic option, it sits at the top of SRAM's DUB bottom bracket lineup on price, with the tradeoff meant to be lower drag than the standard stainless-bearing version. If your frame is tapped for T47 85.5mm and your crankset uses a Road Wide spindle, this bracket is a drop-in match — worth confirming your frame's exact shell width before ordering, since SRAM's DUB T47 lineup also covers 68mm and 77mm shells.
