Not to hijack this thread but I am having the same issue.
I've got myself a Specialized Rockhopper, maybe 3 hours of use and am having a problem when I put pressure on the pedals when in 5th gear. The chain seems to bunch up and pop when I am climbing a hill or really crank on the pedals. I've adjusted the tension screw but the bike doesn't do it in any other gear.. I did purchase the bike "new" on ebay which could mean that the cassette isn't completely new and the teeth could be worn but they all look identical to the other sprockets. I took it to a bike shop on a few occasions, got a free chain out of it and had the derailleurs and other components adjusted. I also tested it in all three sprockets up front and it only does it in fifth. Any ideas would be much appreciated!
