SD Components BB30 Black BMX Bottom Bracket

This SD Components bottom bracket is specially designed for BMX racing. It allows a crankset fitted with a 24mm axle to be installed on a frame with a bottom bracket shell 68mm wide externally and 42mm in internal diameter.
The SD bottom bracket offers both stiffness and practicality. Thanks to its threaded snap-fit system, it can be installed without a press, simply by screwing the two bearings together using a specific Shimano-type spanner.
Fast, efficient and rigid: these are the terms that perfectly describe this SD
Components bottom bracket.
