What is the SRAM DUB BB30 Bottom Bracket 68mm Wide for?

The SRAM DUB BB30 Bottom Bracket 68mm Wide is designed for frames with a BB30 shell (68mm width, 42mm inner diameter) and is for use with DUB Wide cranksets. BB30 is a large-diameter PressFit shell that allows for direct bearing installation without cups, reducing weight and allowing for larger bearing interfaces. The DUB spindle system works with the BB30 shell, and the Wide version provides the correct bearing position for DUB Wide crank geometry on road and gravel bikes.

BB30 frames require bearings pressed directly into the shell. Confirm your frame uses BB30 (68mm width, 42mm ID) and that your crankset is DUB Wide before ordering. Standard DUB cranks require the non-Wide BB30 version.
