I have a M970 crankset. I was hoping to run a Raceface(RF) 9spd 24-36-BG setup (what I use on my other bike with XTs). The 24T RF inner ring does not look spaced out enough to run with the RF combo on the M970 (stupid Sh*tmano). Is it best to run the M970 24T inner ring to get proper spacing or should I use spacers to make the RF 24T inner ring work
