Hi. No, I don't think so. As I understand it, SRAM & Shimano rear derailleurs are pulled by different amounts of cable, & the indexing of a SRAM shifter would miss some gears if it was pulling a Shimano rear derailleur. I believe they **are** interchangeable for front derailleurs. Also, I think the cassettes are interchangeable, if that's your problem (that is, I think you could have a SRAM shifter & derailleur with a Shimano cassette). Hope that helps.
