dgaddis, the cassette make perfect sense now! I put the new cassette on my new wheels when I got them and been riding for almost 2 months on them now. They do show minimal wear, but, Im sure its just enough to cause my problems! Didn’t think that in that time the old chain was gonna cause me that kind of problem, cause I knew I was going to be replacing my crankset and chain. Oh, well, cheap enough, and I should have waited! 😀 Thanks bud!
