Compatibility between Shimano 10s/11s/12s shifters and derailleurs

Conclusion:
1. 10s and 11s Shimano mtb shifters and derailleurs can be mixed. You'll need to select the range of the cassette based on your derailleur specification and chainring size (if you are usind a double or triple crankset)
2. 11s and 12s shimano mtb cannot be mixed
Exceptions: all LinkGlide components (including CUES and XT M8130 and Deore M5130) can be mixed. However, they are not compatible with components not labeled as LinkGlide.
