yup i've done the same thing twice , it's an absoulute f**ker, don't excpect it from a high end free wheel , tarty will should replace it, i would recommend riding it as it is till monday, as they do work just stiff, (if your that desperate) good luck, don't think should effect the threads though as said, no real reason for cracking, i don't think, just bad batch of inner rings i believe,....if mine breaks again and tarrty won't replace it's gunna be a second hand tensile as they seem more reliable then these expensive pieces of shit.
