Substance Mid BMX Bottom Bracket

Achieve precision and smooth functionality around your crank arms with the Substance by BSD

The Substance is a Mid Bottom bracket that comes complete with sealed precision bearings, CNC'd spacers, tube spacers, a sprocket bolt, and all necessary spacers to ensure perfect alignment.

Notice:

Before purchasing a bottom bracket, it is essential to check the compatibility with your frame type. If your frame lacks integrated cups, an American bottom bracket would be suitable; however, if integrated cups are present, the bearings will not fit into the sockets.
