Blah I have a new problem where the chain is popping down to a smaller cog under extreme power. This only seems to happen on the larger half of the cassette and primarily the middle cogs on the larger half.
The der seems to be a in good adjustment as the shifting works well. If I adjust it to try and compensate, then it doesn't shift as good. The hanger and der mounting seems tight. The der seems to be ok (I have 2173 miles on it) I don't think it is bent or anything (plus it is CNC billet der hanger). I replaced the chain back in the fall. I also replaced the housing/cable back then. There might be a little drag now though due to stupid winter so I might replace it again.
The other thing is that I have 1619 hard miles on this XT cassette... could it just be worn out already?
I just recently completed a 29 mile and 21 mile race. I have another on weekend after this weekend so I'd like to get this sorted out quickly.
Any thoughts?
EDIT: This is on a alu HT btw.
