NB.
Does not include wheel spaces : core spacing 7mm.
"Core Spacing" This this the space in the center of the wheel core, between the bearings, roller skates would usually have an alloy or steel spacer to offer support between the bearings, skateboards seldom use this but is advised for longevity.
For other uses such as Brompton Carrier wheel upgrades the lateral load on the bearings is so slight spacers are not necessary.
