Substance Mid BMX Bottom Bracket

For precise and smooth action around your crank-arms, choose the Substance by BSD

The Substance is a Mid Bottom bracket that includes sealed precision bearings, CNC'd spacers, tube spacers, a sprocket bolt, and all other necessary spacers for perfect alignment.

Notice:

Before purchasing a bottom bracket, ensure you check your frame's compatibility. If your frame doesn't have integrated cups, an American bottom bracket would fit, but if your frame has integrated cups, the bearings will not fit in the sockets.
