Alright, thanks. I actually got the hub as a standalone for $.99 and built a wheel out of it. It's not my primary wheel, so it's not a problem. Thanks Sheldon for the advice on it. I'll replace it with the RM-40 that's coming in today ($.99 too). I've got an Acera on my primary wheel. Like I said, there's no point in removing it right now, it's working fine, just was wondering in the event I may have had to take it off. I just wanted to make sure I had interoperability between my rear wheels (my backup was a threadon).
