Sram DUB 121mm PressFit MTB Bottom Bracket in Black

Brand:Sram

Code:BBDUB6001

The Sram DUB bottom bracket series connects crankarms and protects the smooth, long-lasting application of power to the drivetrain.

Sram's DUB spindle is engineered as a unifying component, featuring an oversized spindle designed to work across every bottom bracket specification. This design provides improved crankarm compatibility, enhanced protection from the elements, and longer-lasting performance.

The relationship between the bottom bracket spindle and bearing is the core of DUB technology, where stiffness meets durability. By integrating the relationship between the chainring, crank, spindle, and bottom bracket, this system approach improves drivetrain performance.

Features:

  • One oversized spindle to work across every bottom bracket specification.
  • Significantly lighter than PFGXP system.
  • Easier installation by allowing you to press the bearing cups into the frame.
  • Sealed cartridge bearings available in both stainless and ceramic versions.
