Alright, i recently put on a 9 speed cassette to work with a 9 speed XTR rear derauilleur however i cant get it to fit right. When the derauilleur arm is in the easiest gear (1) the teeth rub on the teeth of the sprocket. How can I adjust the derauilleur so that it does not rub against the teeth of the easiest sprocket. It baffles me and i think i am missing something.
When you look at the back of the derailleur you will see a point in which a #1 phillips head screw hits the dropout. Pull back on the der., and push the screw in to the point in which the jockey pulley does not hit it anymore.

Did you replace the chain at the same time? Assuming you did, how did you set the chain length for you new setup?
Thread the chain around the big ring and largest cog without going through the r'der pulleys and pull taut. Add 1 1/2 to 2 full links (1 inside and 1 outside section = a link), trim the chain at this point and install it through the deraileur pulleys. This should help keep the pulleys off the cog.

No, i did not replace my chain, i am using the same chain i have been using. I did not think it would matter since the only thing i changed was from XT to XTR...but if i will try that. As for adjusting the jackin screw, well i did that and it still rubs even at its full length. I will try the chain replacement though..that might work
