Mission American BMX Bottom Bracket Kit consists of 2 precision sealed bearings, aluminum cups, high-density plastic cone spacers, a center-tube spacer, sprocket adapter and a bunch of adjustment washers.
Notice: The 24mm version is in reality 23.8mm, making it fit with modern freestyle cranks when tightened. If you're looking for a true 24mm size, check the racing category.
Notice: Before buying a bottom bracket, you have to check what type your frame is compatible with. If it doesn't have integrated cups, an American bottom bracket would fit, but if your frame does have integrated cups, the bearings will not fit in the sockets.
