BB SRAM DUB T47 internal bottom bracket
A SRAM DUB crank fits a wide 85.5-92 mm T47 shell using an internal T47 BB, whose bearings sit inboard of the frame. The 46 mm bore comfortably clears the 28.99 mm DUB axle.
Buy the internal, not external, T47 DUB unit for a wide shell. An external T47 BB is too long and will leave the crank unable to preload.
