So I sent off for another HG-50 ( intending to send the defective one back). The newest HG-50 was the same.
When I try I put on another new cassette ( an HG model but very old stock) it runs true ( it is a 7 speed with a spacer).
Does anyone have any helpful input.
Thank you
I had this issue once with a 9sp cassette. The cassette was not seated properly against the rear surface of the free hub. I removed it and re-fitted it a couple of times and the wiggle went away. But I am sure you have tried this by now.
Did you, for some reason, disassemble the cassette? I modify my cassettes ( I remove the second position 14T on a 13-25T and add a 28T at the rear) and sometimes in reassembly the plastic spacers don't sit correctly and mess up the spacing of the cassette cogs.
Good luck.
