All City Track Hubs are designed to be used with standard English threaded track cogs and freewheels.
They will work with most standard English/ISO 1.29"x24TPI track cogs from All City, Shimano, Sugino, Surly.....
They will not work with 1.32"x24TPI Campy, Miche or Phil Wood cogs. While these cogs might start to thread on they will damage the hub.
