A practical choice for anyone fitting or replacing a bottom bracket on a T47 85.5 mm frame with a SRAM DUB Road-Wide crankset.
The SRAM DUB T47 Bottom Bracket is made for SRAM DUB Road-Wide cranksets in frames using a T47 85.5 mm bottom bracket shell. The threaded frame interface gives you a secure, serviceable connection, while the oversized DUB spindle system brings the crank, spindle, chainring and bottom bracket interface together as one durable drivetrain system.
Choose between standard or ceramic sealed cartridge bearings to match your priorities for value, durability and performance. The aluminium cups provide a robust threaded interface, and the Road-Wide configuration includes the required spacer arrangement for T47 85.5 mm shells: 2.5 mm on the left and 5.5 mm on the right. With a 50 N·m installation torque and a 16-notch external bottom bracket tool, it is a practical choice for a compatible road or gravel build or as a replacement for a worn DUB bottom bracket.
Before ordering, confirm that your frame uses a T47 85.5 mm shell and that your crankset is the Road-Wide DUB type. This version is also listed as compatible with the Force DUB 43/30T crankset when used with the supplied Road-Wide spacers.
