SHAMAN & SRAM — Must be MID or LONG cage 10sp rear derailleur.  Always use new 10sp chain of your choice, and set the length depending on if you are riding 1X or 2X drivetrain.  Chain length is also a preference for your personal setup.   Adjust the rear derailleur B-Tension screw down so the upper pulley clears the 40T cog.

Our all new Wide Range 10sp cassette is made for the MTB rider that needs just a little deeper climbing gear, but refuses to give up performance. Smooth shifting is sacred so we focused on the integrity of the shift all while extending the gearing in a fully finished comp level cassette. No awkward gearing steps, no unpleasant missed shifts… simply a proper, 10sp Wide Range cassette.  This is a full cassette and NOT an ‘Expander Adaptor.’ The goal was great shifting, no sacrifice, no compromise ‘Wide-Range’ 10sp MTB cassette, that you could use an unmodified 10sp MTB rear derailleur with. The 11-40 gearing allows this.
