SRAM Bottom Bracket DUB English/BSA (55mm Chainline) 68/73mm

The primary function of the SRAM DUB bottom bracket series is to link crankarms and ensure a smooth, enduring transfer of power to the drivetrain. With an oversized DUB spindle engineered to accommodate all bottom bracket standards, SRAM simplifies crankarm compatibility across the board.

This bottom bracket is intended to be used with DUB Wide cranks with a 55mm chainline. This setup is compatible with some SuperBoost 12x157mm rear hub bikes, but also compatible with newer Boost 12x148mm bikes to allow the use of larger-than-spec chainrings or to fine-tune your chainline.
