You must not have worked on Sturmy Archer 3-speeds, Chuck. That was our source for freewheel spacers. We even had them in different thicknesses, used for adjusting chainline on the internally geared hubs. Not as classy as the aluminum ones, but they worked fine. Anyone ever figure out why the same thread was chosen for English freewheels and BBs? It seems like such an unusual stroke of genius in an industry known for things that were really, really close, but not a fit. Maybe it was to save on threading equipment in the early days by being able to manufacture hubs and BB cups with the same machines.

Those Regina cogs were not defective. It was the design that is to blame. Those innermost threaded cogs sprang into a dish shape when they were trounced on. It was especially noticeable in the larger sizes, but the fact that you had the problem with a 21 just shows how strong a rider you were!
