Hi, I need to replace the pulleys on a 9 speed Shimano XT rear derailleur and had a few questions: 1. Is there a difference between the 9 speed and 10 speed pulleys? Can I buy pulley set for a 10 speed and use it on my 9 speed? 2. Does the pulleys have to match? i.e. can I purchase an XTR version and put it on the XT version? 3. More @Wikipedia
