X9 2x10 front derailure compatability
Does the X9 front derailure need to be paired with the X9 or similar 2x10 sram crankset? I know I'd need the shifters but was wondering if I could use my current crankset with 2 rings or if I would need to get a new one. Thanks

The cage design and geometry is designed to work best with SRAM 26-39 and 28-42 cranks. Will it work with another 2 crank? Maybe, but not optimally. The ten speed cage is also narrower, so if this is a 2x9 bikes you will probably see the 9 speed (wider) chain rubbing the cage in some gear combinations.
