The first two months that I had my HH it shifted like a dream. Then all of a sudden the top rear derailler pulley started rubbing the largset cog on the 11-34 rear cassette. I changed the rear der. hanger but I still had the problem. My LBS couldn't find anything wrong but they put a different B tension screw into the XTR rear derailler that was longer and it pushed the pulley away from the cassette. It was fine for a couple more months but now the top pulley is rubbing the cassette again. I just brought it back to the LBS and they are going to check it out. Has anyone had this problew before?

Tight

I don't know why yours would keep encroaching, but the clearance is tight. I've got a pretty typical setup (23.5" 100X with XTR950 rear derailleur) and with the chain set up per Shimano (large cog to big ring + 2 links) the derailleur smacks the Horst Link and clearance away from the largest cogs is tight. I screwed my B tension screw in quite a ways just to make room. Hasn't hurt shifting, but its something I haven't had to dick with on any other bike. If yours keeps "fallng" in, it'd had to be a bent hanger (which should be obvious), or worn/bent derailleur pivots, I'd think.

Check Your Der

I am also running an 11-34 cassette. Every 6 months or so I have to clean out the der main pivot and regrease it. Takes about 15 minutes. Otherwise the der starts to ride on the 34 cog. Nothing to do with the Hammerhead as I had the problem on my old bike as well (FSR-XC). I replaced two XTR der's before I figured this out.

I had that problem three years ago with an XTR rear derailler. Shimano replaced the defective derailler because of a faulty b screw. I never had the same problem again.

I have a XTR 952 rear derailleur that does the same thing on my NRS 1. When I switched it out with a new rapid rise XT derailleur I received flawless shifting. Your derailleur is probably the culprit.

If that is the problem, then it's a warranty issue at no cost to you. A kewl LBS will give you a new one and deal with the warranty.
