DUB Road and Road-Wide
The SRAM DUB T47 77-A bottom bracket is made for a specific frame standard: a T47 threaded shell that is 77 mm wide and asymmetric. T47 frames use a big 47 mm thread, so the bearings can sit in the shell and you still get the creak-free, easy-service benefits of a threaded bottom bracket.
It takes any SRAM DUB road crankset. The same part works for Road and Road-Wide cranks: Road uses a single 3 mm spacer on the drive side, while Road-Wide uses 2.5 mm on the left and 5.5 mm on the right. Bearings are sealed cartridge units in black aluminium cups.
T47 comes in 68, 77 and 85.5 mm widths and they are not interchangeable, so check your frame spec before ordering. If you are not sure what your bike takes, bring it in and we will measure the shell.
