Hyperglide vs HG10/HG11/HG12

You seem to be asking about the freehub body dimensional standards as opposed to the features of the cassettes that go on each one per se, so I'll limit it to that. One of the confusing things is a ...

Catastrophic hub failure, can the freewheel and rim be saved?

You appear to have a 7 speed freewheel, instead of a more modern cassette. These hubs are chronic for having an unsupported length on the right-hand side, inside the cogs. The best solution is to find ...
