This Sram DUB BB30 Wide bottom bracket for a 68mm case width is your choice if you want to combine your BB30 frame with wider cranks.
The spacers create space for the crankshaft thus widening the chainline. This shifts the electronically controlled AXS 2x12-speed front derailleurs to the outside, which in turn allows wider tires to be used, for example in Gravel applications.
The DUB offers you the perfect compromise between large bearings and axle stiffness.
