Substance Mid BMX Bottom Bracket

Opt for the Substance by BSD for precise and smooth performance around your crank-arms

The Substance features a Mid Bottom bracket that comes with precisely sealed bearings, CNC'd spacers, tube spacers, a sprocket bolt, and all the necessary spacers for accurate alignment.

Attention:

It is crucial to verify the compatibility of your frame type before purchasing a bottom bracket. If integrated cups are absent, an American bottom bracket would be suitable, whereas, with integrated cups, the bearings will not fit in the sockets.
