Hi, I have a 2013 RM element 970 RSL BC Ed. It has X9, with a triple crank. I want to ditch the triple for a 1x setup. I am eyeing the shimano XT Deore M1000 group including the crank. I currently have an RF turbine crank. I want to ditch that for a Shimano XT M8000 crank. It is being offered with boost and non-boost.
Do I need the boost or non boost crank?
Also, long cage or medium cage?
ps: Not sure if it matters, but I will be going with 11-46T XT cassette.
