Mission American BMX Crank Bearing Set (Black)

The Mission American BMX Bottom Bracket Kit consists of 2 closed precision ball bearings, aluminum cups, high-density plastic cone spacers, a centertube spacer, sprocket adapter and some adjustment washers.

Note: The 24mm version actually measures 23.8mm, meaning it fits modern freestyle cranks when tightened. If you're looking for a 24mm crankset, we recommend checking out the race category.

Note: Before buying crank bearings, it is important that you check which type your frame is compatible with. If it does not have integral cups then American crank bearings will fit, but if your frame has integral cups these ball bearings will not fit.
