|All of them except the pre 9 speed DA.The pre 9 speed DA can be used with a Shimano 9 speed shifter, to shift a Shimano 8 speed cassette.|

|I guess I wasn't very clear about what I was trying to accomplish. I would like to use a Shimano XT 8 speed rear derailleur in conjunction with a 9 speed cassette and Ultegra STI 9 speed shifters.
I don't believe I would have any problem adjusting the stops (although I haven't tried). I was just wondering if the 8 speed derailleur moves the same distance as the 9 speed given the same amount of cable travel?

|It should work because the spacing is a function of the shifters and cog spacing. The derailleur has no "stops" to adjust. I recently upgraded a friends bike with 9-speed shifters and cassette, the old "7-speed" derailleur worked with them flawlessly.
|Thanks Much - I'll stick with plan A then (nm)||B2|

|The answer was yes.EXCEPT, don't try using a pre 9 speed DA.the throw ratio of that derailer is different than the others.|| |
