I installed an x9 der. with x7 shifters and I just can't get it dialed right. I have a new pc69 chain and an older XT cassette. The only thing I can think of is the little piece of housing from the der. to the seatstay is too short, but that shouldn't make too much difference since it's direct pull.

The tension barrel doesn't help, two clicks one way and the chain is skipping down, two the other way it's skipping up. One click either way doesn't do anything. It really only happens with the top three cogs.

I'm pretty sure the hanger is strraight. Any ideas?

Ok well one it could be the old cassette with a new chain. Also is could be your cable housing length. I'd try those to first. Also your b-tension screw should be set just so there is no pulley-chain-cassette interference to have soft crisp shifts.

I've had that problem before

and it was because of gunked up cable housing. You can't get the darn derailleur to shift to smaller cogs without setting the cable too loose. It shifts ok to the smaller cogs, but won't go back up. So then you tighten the cable, and now it shifts up to the bigger cogs, but because of all the friction in the housing, the cable doesn't release properly when you try to shift down the cogset. Is this the problem you're having? Try shooting some tri-flow through the rear housing (or just get a new cable/housing set). Hope this helps.

just resolved two days ago

I had a x.9 setup on a different bike and liked it so much, I bought a X.7 setup (pods and rear d) for my hollowpoint. Had trouble right away, it reminded me of a friends bike where he put an 8 speed chain in a 9 speed setup.
What fixed this was cranking the B adjustment screw far enough in to get the top pulley to come below center on the cassette, not in front. It is back farther than in the instructions, but cured what ailed. I always had some degree of ghost shift on this frame with shimano drivetrains and now have none at all.
Hope this helps!

I'll try that. I know the directions say there should be a 1/4" gap between the pulley and the cog. I thought that seemed awfully close. Another thing is, I am completely dysfunctional when it comes to derailleurs, I can't believe I made it this far.
