Wheels Manufacturing freewheel shims are designed to adjust the chainline of a BSA (standard) threaded freewheel or bottom bracket cup that has a lip.
Wheels Manufacturing freewheel shims 1.0mm and larger are machined from aluminum. For most hubs 2mm of spacers is the most that you can adjust while still having enough thread contact between the freewheel and hub.
