The NCU (National Cyclists' Union) was the organising body for cycle racing in the UK.

Their opposition to massed start road racing except on closed circuits led to the creation of the BLRC (British League of Racing Cyclists') and the introduction of (open) road racing even though at first it meant you were banned from the NCU if you took part.
The two bodies merged to become the BCF.
