SRAM DUB PressFit Bottom Bracket – 89/92mm (PFDUB)

The SRAM DUB PressFit Bottom Bracket (PFDUB) is designed to simplify modern drivetrain compatibility while improving durability and reducing weight. Built around SRAM’s single oversized DUB spindle, this system allows one crank standard to work seamlessly across a wide range of frame designs.

Using a PressFit design, the bearing cups are pressed directly into the frame, making installation more straightforward while maintaining precise alignment. Compared to older PFGXP systems, this bottom bracket is significantly lighter, without sacrificing strength or longevity.

Inside, two fully sealed cartridge bearings deliver smooth rotation and long service life, even under high loads and adverse riding conditions. This makes it an excellent choice for modern mountain and trail frames using wider PressFit shells.

Why we stock it at Go Grava:
Because DUB reduces compatibility headaches while delivering quieter operation and longer-lasting bearings.
