A practical choice for riders replacing a worn press-fit unit or building a DUB-equipped MTB with a PF 89.5 mm or PF 92 mm frame shell.
The SRAM DUB PressFit bottom bracket is designed for DUB cranksets and compatible press-fit MTB frames with a PF 89.5 mm or PF 92 mm shell and 41 mm inner diameter. The cups press directly into the frame, avoiding a threaded bottom-bracket interface and providing a straightforward installation when the frame standard is correct.
Inside, sealed cartridge bearings help shield the bearing system from contamination during regular riding. You can choose between standard and ceramic bearing versions, while the steel cups provide a robust foundation for everyday trail, MTB Wide, downhill, fat-bike and Super Boost+ builds.
Compatibility depends on more than the crank alone, so check your frame shell width, rear hub spacing, chainring offset and required chainline before ordering. The available chainline range covers multiple SRAM drivetrain configurations, with 2.0 mm and 4.5 mm spacers included for the PF 89.5 / PF 92 MTB setup.

Installation
DUB
The oversized DUB spindle creates a unified interface between the crank, spindle, bearings and bottom bracket. This gives you broad crankarm compatibility while combining stiffness, durability and smooth drivetrain performance.
PressFit
The bearing cups press directly into a compatible frame shell, simplifying installation and avoiding a threaded bottom-bracket interface.
Sealed cartridge bearings
Sealed cartridge bearings help protect the bearing system from contamination and are available in standard or ceramic versions.
