I was actually looking into getting this wheelset a couple months back, so I tried to read as much as I could about them. Almost every thread I read, they were saying that the only problem people run into is that the lock ring sometimes loosens (and I'm still not too sure why), but my LBS said that every once in awhile you just have to tighten the ring. Other than that, those wheels are nice and I still wouldn't mind picking some up.
