I picked up one for my tour and I haven't had any issues. I ended up doing a shorter tour (3000 miles), with no issues. A LBS guy asked me if I thought about failure, I told him I honestly hadn't. He claimed a normal lifespan for a hub could be about 7-10k miles. So far no problems, and to agree with everyone else, I'm really happy about the purchase.
