VERY IMPORTANT: THIS WILL NOT FIT A REGULAR BMX FRAME - a standard 1" threaded fork BMX frame takes 32.5mm bearing cups - this headset has 30.0mm cups and is designed for Japanese (and other Asian manufacturers) road bikes - but it may fit old school MINI BMX frames (these are for smaller riders and used wheels with 451mm bead diameter). As always MEASURE THE INNER DIAMETER OF YOUR HEADTUBE and CROWN RACE before ordering.
