    SRAM X5 9 vs. 10 speed compatibility

    I've got a '13 Specialized RH that has 9x3 SRAM X5 on it (drive train swap w/ my wife's bike... long story). I'm interested in converting it to 10 speed but I'm wondering if the existing derailleurwill work on a 10 speed cassette. Obviously I need a different shifter but hoping the existing derailleurwill work. Not near the bike right now to look and see specifically what model X5 it is.

    Democracy is two wolves and a lamb voting on what to have for lunch. Liberty is a well-armed lamb contesting the vote!

    It probably won't. I'm pretty sure 9spd and 10spd Sram derailleurs have different pull-ratio requirements because of different anchoring points.

    Sorry.

    Yep 9 to 10 speed means a new rear derailleur with Sram or Shimano.
