Hello Adam,

Good to read you have it all well sorted.

These Atom/Normandy/Maillard hubs are marked by the manufacturer with their thread specification.

If they have a groove in the area just outboard of right flange and just inboard of the threads they are BSC/ISO dimension. If this area is smooth/ungrooved they are metric/french threaded. This manufacturer does not offer italian thread.

All Schwinn Approved versions of these products are of course BSC/ISO.
