The BB30-SHIM adapters allow you to run 24mm Spindle Cranks (Shimano, FSA, etc.) or 22/24mm Spindle Cranks (SRAM/TruVativ) to work on BB30 frames
Simply tap the adapters into the 6806 bearing in the BB shell, install the spindle and cranks. • Use our Crank Spindle Spacers to adjust your chainline, or take up any side-to-side movement in your cranks.
