SRAM DUB PressFit 30 Bottom Bracket – PF30, 68/73mm

The SRAM DUB PressFit 30 Bottom Bracket is built around one simple idea: one oversized spindle standard that works across nearly every frame and drivetrain configuration. By pairing a 28.99mm DUB spindle with lightweight PressFit cups, SRAM delivers a bottom bracket that balances stiffness, durability, and broad compatibility.

Designed for both road and mountain applications, this PF30 bottom bracket uses PressFit cups to reduce weight while maintaining excellent bearing alignment and longevity. The system features greater bearing durability than previous designs, along with an integrated adjuster that simplifies setup and eliminates side-load issues during installation.

The included 3mm spacer allows fine-tuning across different crank and frame combinations, making this an ideal solution for modern builds and service replacements alike.

Why we like it at Go Grava:
Because DUB simplifies compatibility without sacrificing performance—and that makes both builds and long-term service easier.
