American BMX Bottom Bracket Kit

Mission American BMX Bottom Bracket Kit is composed of two precision-sealed bearings, aluminium cups, high-density plastic cone spacers, a centre-tube spacer, a sprocket adapter, and a variety of adjustment washers.

Notice: The 24mm version is actually 23.8mm, ensuring compatibility with modern freestyle cranks when tightened. If you require a genuine 24mm size, please refer to the racing category.

Notice: Before purchasing a bottom bracket, it is essential to confirm the type compatible with your frame. If your frame lacks integrated cups, an American bottom bracket would be suitable, but should your frame have integrated cups, the bearings will not fit the sockets.
