Hard to get and needs to be modified slightly to fit Brompton by turning axle endcaps down from 9mm to 8mm. Note that hubs are drilled 14h and are not staggered (holes in left flange are directly across from holes in right flange). Flange PCD can not be measured directly due to the odd number of holes on each flange, but can be calculated using the center-to-center distance of two nearly-adjacent holes: http://www.had2know.com/automotive/calculate-bolt-circle-diameter.html -Karl
