The Sram Dub PF30 Road 73mm bottom bracket has a very simple task: to connect the crank arms to one another and to ensure a long-lasting power transmission into the drive.
For this specific requirement, Sram designed the DUB crankshaft: a single oversized shaft that works with all bottom bracket standards.
For better crank compatibility, better protection from the elements and long-lasting performance - more stable, smoother, easier.
- An oversized shaft that works with all bottom bracket standards
- Improved shelf life
- Easy construction
- Lightweight PressFit cups
- Frame interface: 73mm
- Storage variant: standard
- Shaft diameter: DUB
- Bearing shell material: aluminum
