The Promax "EX-1" BMX Race Bottom Bracket - 24mm is an external bottom bracket for cranks with a 24mm spindle and fits internally threaded Euro BSA/BSC shells with 68 or 73mm width. The cups are CNC machined from 6061-T6 aluminum and support the sealed bearings well in the shell, so the crank turns easily and without play. Three spacers are included.
