    What XT Rear Derailur to Get?

    I have a 2006 Gary Fisher Paragon 29er and am going to replace my Sram X9 rear derailur with a Shimano XT and throw some XT shifters on as well. How do I know what XT derailur to get. I was told there is a formula to follow to decide between long cage, med cage, etc.

    If anyone knows which XT derailur to go with please let me know.

    If you want to be on the safe side always go with a long cage. If you have a 34t cassette you should get the long cage.

    Also get long cage if you have a three chainring setup so that the rear derailleur can take up the slack of the longer chain required in such a setup (ie. at extreme gear selections). I've owned both med. and long cage XT rds and the med. cage has better clearance and seems to shift a tad faster (it also requires a shorter chain but you risk locking up the drivechain if you cross chain).
