Description

SRAM DUB bottom brackets connect the cranks and provide smooth, long-lasting power transfer. The DUB spindle is designed as a common component, with a single-size spindle that fits all bottom bracket specifications. The DUB system provides improved crank compatibility, greater protection from the elements and longer service life.

  • One oversized spindle fits all bottom bracket specifications.
  • Significantly lighter than the PFGXP system.
  • Installation is easier because the bearing cups can be pressed into the frame.
  • Sealed cartridge bearings are available in stainless steel and ceramic versions.

DUB technology

The relationship between the bottom bracket spindle and bearings is at the core of DUB technology, bringing stiffness and durability together. The system simplifies integration between the chainring, cranks, spindle and bottom bracket. This approach to creating a complete system helps improve drivetrain performance.
