Substance Mid BMX Bottom Bracket

Experience precise and smooth motion around your crank arms with the Substance by BSD

The Substance is a Mid Bottom bracket, equipped with sealed precision bearings, CNC’d spacers, tube spacers, a sprocket bolt, and all additional spacers required for perfect alignment.

Notice:

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