SRAM Dub T47 Bottom Bracket

The SRAM Dub T47 Bottom Bracket is designed to create a dependable connection between a compatible SRAM crankset and a T47-equipped road frame. Rather than treating the crank, spindle and bottom bracket as separate components, SRAM develops Dub as an integrated drivetrain system focused on smooth operation, durability and straightforward compatibility. It is suited to riders building a new road bike or replacing a worn bottom bracket while retaining the intended SRAM drivetrain interface.

Built Around Dub. SRAM's approach centres on the relationship between the crank spindle and bottom bracket bearings. By engineering these components as part of the same system, Dub is intended to balance stiffness with durability while simplifying compatibility across different frame standards. This makes the T47 version a purpose-built solution for modern threaded road frames using compatible SRAM cranksets.

Made for Lasting Performance. Protection from the elements is a key part of the Dub design philosophy, helping the bearing system continue to operate smoothly through regular riding and changing conditions. The threaded installation also provides a straightforward interface for workshop servicing and replacement. For riders using SRAM road components, the Dub T47 Bottom Bracket offers a manufacturer-matched foundation designed to work quietly in the background while maintaining consistent drivetrain performance.
